Authority and potentials
inter is now on the ho­
rizon here at home.
With the holidays just
around the corner, it
won't be long before
Old Man Winter will be barking at
us yet again. Oh well, my attitude
has always been that "the sooner
it gets here, the sooner it's over." I
clearly remember just a few months
ago reflecting about how long this
past winter seemed to hang around
here in Indiana. It was a long and
brutal one that I sure hope we don't
see repeated.
As I am writing this column, I just
returned from Oshkosh. A bunch
of our Vintage Aircraft Association
(VAA) volunteers always get together
in early October to winterize our
campers that we use throughout the
year when we attend the work parties
and various other EAA events. It's
always a fun and laid-back weekend
lacking the routine hustle and bus­
tle of preparing for EAA AirVenture
Oshkosh. Although we didn't have
the best of weather this past weekend,
we sure made up for it in enthusiasm
and a great deal of camaraderie. Many
thanks to all in attendance, especially
Bob Lumley and Georgia Schneider
for preparing a great meal for us all
on Saturday evening at the Aeroplane
Factory on the EAA grounds.
September was a very busy month
for us here at the VAA Chapter 37
hangar. It all started early in the
month during the Labor Day week­
end when we hosted New Standard
barnstormer rides during the annual
Auburn-Cord-Duesenberg Auto Festi­
W
val held every Labor Day weekend in
Auburn, Indiana. If you haven't had
the opportunity to ride in a New Stan­
dard, you really need to experience
this aircraft. The crew of the New
Standard is a bunch of crazy "wing
nuts," so we had a really good time
hosting them for this event. Many
thanks to "Scooter" and his crazy cast

of aviators for a fun-filled weekend.
Our chapter also hosted the 2009
Stinson fly-in at Auburn in mid­
October. This was also a fun week­
end with good weather and ex­
cellent attendance. We topped off
the month by hosting the EAA
B-17 tour at Auburn. Although the
weather was a bit challenging, we
again enjoyed hosting the aircraft as
well as the crew. A good number of
our local B-17 vets again showed up
to share their experiences with hun­
dreds of local visitors to the tour.
Thanks for coming, guys. We really
enjoyed our time with you.
Mix that all in with a couple of
Young Eagles events, and you can
see why I use the term "busy." Many
thanks also go out to all of the local
chapter volunteers who supported
us in hosting all of these events. We
simply couldn't do it without you!
The world of sport aviation con­
tinues to face unprecedented chal­
lenges to our right to fly. It seems
to me as though nearly every layer
of government regulators seems to
think that they aren't doing th eir
job unless they periodically fire a
shot across our bow to make sure we
haven't forgotten about their "au­
thority." But recently there was a bill
introduced in the House of Repre­
sentatives that will potentially limit
their authority to arbitrarily regulate
those of us who are engaged in this
pleasure we call aviation.
On September 30, a good number
of genera-aviation-minded representa­
tives introduced HR 3678, that would
rein in the Department of Homeland
Security's (DHS) absolute power to is­
sue security directives that severely
impact aviation. It seems as though
the DHS has ruffled some feath ers
inside the beltway with its incessant
practices of issuing what are referred
to as safety bulletins. A number of
which have included unwarranted
impact on our access to free skies. If
this bill passes the House, it would
effectively limit DHS in its ability to
arbitrarily pass security directives un­
less they prove to be in response to an
imminent threat, and then only for a
maximum of 180 days. If such a direc­
tive needs to be in place for a period
longer than 180 days, the DHS would

Sully and Skiles New Young Eagles Co-Chairs Sully Sullenberger (left) and Jeff Skiles, co-chairs of the EAA Young Eagles program.
EAA members expressed surprise and excitement wh en it was announced
September 29 that US Airways Flight 1549 pilots Chesl ey "Sully" Sullenberger
and Jeff Skiles would be the new co-chairs of EANs Young Eagles program.
"Many people have contacted me and said w hat a great choice; it was unex­
pected, but what a great choice fo r the next step to lead the Young Eag les pro­
gram;' said EAA President/Chairman Tom Poberezny. You can read more about
the new co-chairmen on page 81 of fAA Sport Aviation.
Since vintage aircraft make up the majority of the lightplane general-aviation
fleet, it probably comes as no surprise to learn that the majority of the 1.5 million
Young Eagles flown so far were flown in aircraft built priorto 1971, and one of
the new Young Eagles chairmen expects that trend to continue for him in a very
personal way; you can read an interview with Jeff Skiles and see a slide show
of his "new" Waco YOC in issue No. 3 of Vintage Aircraft Online, the VANs newest

EAA Responds Immediately
to Anti-GA Airport Stories
Inaccurateclaims that small airportsreceive
disproportionateamount of federal money
When two national news outlets
recently produced stories critical of
funding for general-aviation (GA)
airports, EAA and other aviation or­
ganizations promptly stood up and
set things straight. USA Today and
NBC ran stories on September 17
that claimed smaller airports receive
a disproportionately large amount of
federal funding to upgrade those fa­
cilities at the expense of the nation's
commercial hubs.
"This is very upsetting but not un­
expected-it's obvious the airlines are
2
NOVEMBER 2009
still trying to fix their broken busi­
ness model by inflaming the public
with one-sided media stories," said
Tom Poberezny, EAA chairman/presi­
dent. "For several years, the airlines
have tried to shift the burden of sup­
porting our nation's airport infra­
structure by tossing it on the back of
general aviation. It was wrong before,
and it still is."
What the news o u tlets failed
to report is that aviation fuel taxes
paid by GA annually exceed grants
distributed for all airport improve­
ments, yet those funds are perenni­
ally raided to ease the FAA's general
budget shortfall. Hub airports also re­
ceive three times more federal funds
than do GA airports, and GA users
pay five times more in fuel taxes
than the airlines to support the air
traffic control system, the primary
users of which are the airlines.
"EAA agrees with one item from
the USA Today story-the nation's
small airports are underutilized," Po­
berezny said. "If major hub airports
are overcrowded but smaller airports
are ready and eager to serve avia­
tion, why would it make any sense
to wage war on small airports? They
are all essential parts of the nation's
transportation system."
EAAer Keys Mexican
ElT Rule Extension
Thanks to coordination efforts
by EAA member Rick Gardner, EAA
791548, of travel service provider Ca­
ribbean Sky Tours, the Mexican gov­
ernment extended its emergency lo­
cator transmitter (ELT) rules through
April 2010 for general-aviation air­
craft flying in Mexico. The extension
provides a procedure that will allow
certain U.S. pilots operating 121.5
MHz ELTs to fly into Mexicothrough
April 2, 2010. After that date, all
general-aviation aircraft flying into
Mexico must be equipped with an
operable 406 MHz ELT.
Gardner and his wife, Pia, own­
ers and operators of Cancun, Mex­
ico-based Caribbean Sky Tours, are
longtime AirVenture and Sun 'n Fun
exhibitors and regularly conduct fo­
rums on flying to Mexico, Central
America, and the Caribbean. Rick
Gardner worked directly with the Di­
reccion General De Aeronautica Civil
(DGAC, the Mexican equivalent of
the FAA) on the 406 MHz ELT regula­
tion for the last two years.
"We have had a very good rela­
tionship with the DGAC for many
years and have worked together on
a number of different issues to facili­
tate the arrival of visiting general avi­
ation aircraft into Mexico," he said.
"We are also on the executive coun­
cil of the Mexican Federation of Pi­
lots (FEMPPA) and are an authorized
distributor for INEGI, the Mexican
charting office, which allows us to
stay abreast of Mexican aeronautical
issues and products."
VAA Volunteer of the Year Awards TSA and DHS Merge Border Flight
Crossing Procedures
Two Department of Homeland Se­
curity (DHS) agencies recently merged
their border security programs to
eliminate redundancy as well as the
paperwork burden of international
travelers. The Transportation Secu­
rity Administration's (TSA) Interna­
tional Waiver program will be folded
into Customs and Border Protection's
(CBP) Advanced Passenger Informa­
tion System (APIS).
This will satisfy a commitment
made at AirVenture 2009 by TSA's new
general-aviation manager, Brian De­
lauter, and CBP's APIS program man­
ager, Eric Rodriguez, to improve the
border-crossing procedure for general­
aviation pilots through collaboration.
The info merger will allow pilots to
complete only the CBP electronic APIS
paperwork to fly across U.S. borders.
EAA, which has advocated for a less
onerous system, has prepared a guide
on how to navigate the current re­
quirements until the new process is fi­
nalized. That is available at www.EAA.

During the fall board meeting, Jim Swol (right) was presented with a commemora­
tive clock and a certificate commemorating his selection as the 2009 Art Morgan VAA
Flightline Volunteer of the Year.
ach year the Vintage Aircraft Association honors two of its own for their service to the VAA
and its members during the annual convention. As it is every year, it's tough to pick just one
person for such an honor, but this year was especially challenging, as we had afantastic group
of volunteers step it up an extra notch during the months prior to this year's amazing event, and
during the convention .
The Art Morgan VAA Flightline Volunteer of the Year comes to us all the way from the state
of Maine. For years we have both marveled and worried at the willingness of the VAA flightline
volunteers to keep going and do whatever was requested of them, and Jim Swol epitomizes that
volunteer work ethic- always on the spot, doing what needs to be done, year after year.
The VAA Behind the Scenes Volunteer of the Year is actually a twosome this year. The way­
beyond-the-call-of-duty work spearheaded by these two volunteers made it possible for us to com­
plete the Vintage Hangar on time and under budget. Thanks to the work by Archie James and Michael
Blombach, this year's honorees for the award, the 40-plus volunteers who helped finish out the proj­
ect were kept busy and focused so that we could all enjoy our new facilities when AirVenture started.
Our sincere admiration and heartfelt thanks to Jim Swol, Archie James, and Michael Blombach
for their hard work. Congratulations, gentlemen!

o what would a former high
school track star, Army Spe­
cial Ops soldier, and para­
chute ace want for a vintage
aircraft? If you're a guy like
Jack Tiffany of Spring Valley, Ohio,
you'd go for the most unusual thing
you could find-an Autogiro.
There was only one problem for
the energetic Tiffany, a Vietnam vet­
eran now in his seventh decade; he
couldn't find one to restore. Other
neat projects came and went for
his laid-back confederation of re­
storers that bill themselves as Lead­
ing Edge Aircraft (liOn the Trailing
Edge of Technology" is its motto). A
Fairchild Kreider-Reisner 21 biplane,
a Fleet 16B, a couple of Davis D­
1Ws, and a smattering of Wacos and
other ancient but lovable aircraft
passed through the hangar doors,
but an Autogiro proved elusive. He
searched for one for 28 years.
Enter the third generation of avia­
tion fanatics in the Tiffany sphere
of influence. Jack's father had been
an Air Force crew chief, and for Jack,
aviation was a major part of his life.
Later, when he married Kate (an
avowed aviation nut herself, she's

served as a volunteer judge at EAA
AirVenture Oshkosh), he got a bo­
nus in the bargain, Kate's son, Nick.
The young boy soon became as en­
amored as his stepfather with avia­
tion, and as a teenager Nick became
quite the aviation sleuth, digging up
tidbits of handy aviation knowledge.
That tenacity would payoff in 1999,
when he came to Jack with the reve­
lation that there was an Autogiro out
there that could be restored. In fact,
there were two!
It didn't take long for Jack and
Nick to track down Al Letcher of Mo­
jave, California. AI, a longtime col­
lector of vintage aircraft, had bought
the remains of a Pitcairn PA-18 from
Ted Sowirka, who had owned it for
43 years. But how it came to be in his
hands is a story that will warm the
Since it is a fixed-spindle system,
the rotor head is relatively simple.
The cables and the bungee cords
attached to them act as limit stops
when the rotor is rotating slowly or
is stopped. To the sides of the rotor­
attach hinges are the squarish rub­
ber pads that, in combination with
the dampers installed farther out on
each blade, act to dampen and limit
the lead/lag movement of each rotor
blade as it flies around the rotor disc.
To the left is the pre-rotator gearbox,
which engages with the helical spur
gear bolted to the bottom of the ro­
tor head. The pre-rotator is used to
spin up the rotor blades to a stable
rpm before the takeoff roll is started.
Having a spun-up rotor allows the
rotor to be started and brought up to
speed without the hazard of taxiing
with a low-speed, unstable rotor sys­
tem, and it significantly reduces the
takeoff run.
heart of many a potential restorer
who still has hopes of finding his
own aeronautical Holy Grail.
History
The Pitcairn PA-18 Autogiro was
created by the company after the
firm had created quite a name for it­
self with the PCA-2 Autogiro, a large,
expensive craft that was bought by a
few firms for its novel appearance,
which, since it attracted a lot of at­
tention, made it a suitable platform
for advertising. But the PCA-2 with
a 300-hp Wright Whirlwind on the
nose and a 4S-foot rotor span was
a big rotorcraft. It could carry three
with ease, and its hulking presence
on the ground made it hard to miss.
(" Autogiro" with a capital A is the
spelling coined by the Cierva Auto-
By necessity, the rotor blades are quite flexible, which require the trailing edge
of each blade to be segmented. This leather patch on the trailing edge covers
one of the slip joints on the trailing edge.
When running, the short stacks on the 160-hp, five-cylinder Kinner-R-55 give
the Pitcairn a distinctive bark in flight.

After arriving in Jim Hammond's shop, the Pitcairn's pieces
were assembled as much as possible so the restorers
could get a better idea of just what they had.
After 60-plus years, it's not surprising that the blade rub­
ber dampers were not usable, so a new set were cast us­
ing new urethane rubber material with the correct 90
durometer hardness.

aircraft with unpowered rotors; the
FAA simply avoids the entire issue
by calling them "gyroplanes.")
What was also needed was a
smaller, more compact version,
something that a well-heeled owner
could purchase and fly. Harold Pit­
cairn, the founder of the aviation
manufacturing concern that bore
his family name, had started his firm
in the 1920s building mail-hauling
aircraft renowned for their struc­
tural strength and safety with regard
to their ability to protect the pilot in
the event of a crash. Harold's long­
time pursuit of the safe operation

NOVEMBER 2009
A restorable PA-18 rotor head and pre-rotator gearbox
was obtained from Steve Pitcairn, and thanks to his inter­
est in his father's company history, Steve was also able to
supply a set of drawings so Phil Riter could build a new
rotor mast.
The rotors were complete, with steel spars that were
inspected and deemed airworthy. All-new wood com­
ponents were used to restore the blades. With the expe­
rience of building the first set, the Leading Edge gang
continued to build blades as spares.
of aircraft led him to a collaborative
agreement between his company
and Juan de la Cierva, the inventor
of the Autogiro. Assigned the exclu­
sive rights to license and produce
the Autogiro in the United Sates, the
Pitcairn-Cierva Autogiro Company
of America pursued the vision of a
safe aircraft that could be landed
just about anywhere.
Harold Pitcairn wanted that ca­
pability to be within reach of any­
one who could fly, and a personal
aircraft was just the next logical step
in the progression of the Autogiro.
The first version, the PAA-l, was ba­
sicallya scaled-down PCA-2, with
a fixed-spindle rotor system atop a
fuselage powered by a 125-hp Kin­
nero One version was built with the
Chevrolair engine and an odd tail
wheel/nose wheel configuration.
The PAA-1 was well-received but
it was considered significantly un­
derpowered (25 were built and de­
livered in the darkest period of
the Great Depression of the early
1930s), but it wasn't exactly what
Harold wanted. The factory came
up with the next version, a slightly
larger aircraft that was destined to
be just what Harold Pitcairn wanted.
In fact, he liked it so well that in
1932 when he rented a beach house
on the Jersey shore, he used his per­
sonal PA-18 as his weekend "com­
muter car" to cover the 80-mile drive
in half an hour, rather than battling

It seemed the little PA-18 had
once again cast its magic spell on yet
another aviator. Anne Strawbridge
came to name the autogiro Isobella.
In 1936 and 1937, she sent similarly
complimentary letters to Harold Pit­
cairn expressing her admiration for
Isobella, and for the instruction be­
ing provided by Mr. Lukens, one of
Pitcairn's instructor pilots. She flew
the blue 'giro more than 90 hours
by mid-1937, enjoying the opera­
tional peace of mind that the Auto­
giro gave her. She wrote later:
"I have been amazed at Mr.
Luken's ability as an instructor.
When he took me on, I could not
have been a more unpromising stu­
dent. Now I get into the ship as tran­
quilly as into my Ford car-and with
a lot less feeling of risk in the air than
on the highway."3
A couple of explanations are in or­
der. The color, as described to me by
Carl Gunther, the archivist of the Pit­
cairn Aircraft Association, was dark
blue with a light blue stripe with a
white keyline around the stripe.
The Mr. Ray she refers to in the
letter is Jim Ray, Pitcairn-Cierva Au­
togiro Company's vice president
and one of the most accomplished
Autogiro pilots in history.
While there is fascinating mate­
rial to learn more about in Auto­
giro history, we need to skip a few
years ahead to complete the his ­
tory of NC12678. It's 1939, and
thanks to the German U-boat men­
ace, the British are having a devil of
a time getting their war effort and
nation supplied via convoy across
the North Atlantic. Looking at any
means at their disposal to gain an
advantage in knowing where the
U-boats were lurking, the British
contracted with the Pitcairn-Larsen
Autogiro Company, a successor to
the original company set up by Har­
old Pitcairn, to remanufacture the
remaining PA-18s into sub-spotting
Autogiros that could operate from
small decks on ships within the con­
voys. Using the PA-18 as a base gave
them a quick start on the creation of
an Autogiro suitable for the purpose.
Technological advances in rotor
and flight control systems, includ­
ing the now perfected direct-control
rotor head, gave the remanufactured
aircraft, now called the PA-39, im­
proved performance, and the in­
stallation of a 16S-hp Warner Super
Scarab gave it added reliability. All
the company had to do was buy back
the remaining PA-18 Autogiros from
the owners, run them through the
remanufacturing process, and then
load them on ships for delivery to
the United Kingdom. That's just
what they did with all of them. All of
them except one. Anne West Straw­
bridge's Autogiro wasn't on the list.
There's no record of what conver­
sation or letter transpired between
the company and Anne Strawbridge,
but based on her lovely letters to Har­
old Pitcairn, I can't imagine it was
anything but a very polite "0h my
goodness, no, I could never sell it"
type of refusal to sell little Isabella so
that it go off to war. In any event, it
was not part of the group to be con­
verted to the PA-39 configuration.
Her strong attachment to the little
blue Autogiro is what saved it for res­
toration many years later; only two
of the PA-39 Autogiros ever made it

to England. Three were lost at sea in
a torpedoing of the cargo ship carry­
ing them, with at least one remain­
ing in the States, where it was used
for research and development work.
There is one PA-39 remaining, re­
stored and on display in EAA's Pit­
cairn Hangar on Pioneer Airport, a
gift of Harold Pitcairn's son, Stephen.
After civilian flying was banned
for the duration of the war along the
East Coast, Anne never again flew her
beloved 'giro. She died in 1941 at the
age of 58, willing the little rotorcraft
to her brother, John Strawbridge.
A few years later, just after the end
of World War II, the ownership of
the Autogiro flipped back and forth
a few times before being sold to G&A
Aircraft. It was Wind-damaged, and
later, Firestone Aircraft (the successor
to G&A Aircraft) repaired it.
They didn't keep it long (G&A also
operated the remaining PA-39), sell­
ing it to Sky Voice Inc. of East Or­
ange, New Jersey, on March IS, 1947.
A shoreline advertising company,
Sky Voice planed to pull banners and
eve n put a big speaker in the 'giro
to generate advertising publicity.
There's no record it actually did that
with the Autogiro, but it's fun, if not
12 NOVEMBER 2009
a bit unnerving, to imagine a voice
from the sky exhorting those on the
shore to "Eat at Joes!"
Four years later, the Wyoming
Valley School of Aviation at Wilkes­
Barre, Pennsylvania, acquired the
Autogiro after Joseph Budjinski of
the school determined, by query­
ing the Civil Aviation Authority,
the most recent registered owner.
Within the next two years the
school folded, and on July 3, 1954,
a flight school on the same field,
Morlin Air Service, sold NC12678 to
Ted Sowirka, who brought the still
mostly complete 'giro to Old Star
Airport near Langhorne, Pennsyl­
vania. Most likely it was sold by the
flight school as part of a settlement
for payment, and while such things
happen, if they're not executed
properly, it can cause a big headache
for those who follow, as we'll see
later in this article.
While the rotor blades were
stored in a hangar, the partially re­
worked fuselage sat outside. While it
was there, Warren D. Shipp, a transit
policeman from New York City who
had an interest in aviation, and Au­
togiros in particular, spotted it sit­
ting out in the grass. Shipp, one of
the earliest American Aviation His­
tory Association members (No. 14)
sent a couple of photos and a letter
that were published in the first issue
of American Airman magazine (Sep­
tember 1957), imploring someone
to save the Autogiro before it was
lost to history. That story helped
Nick Hurm track down the where­
abouts of the PA-18. (See the photo
in this article.)
Sometime later, after those pho­
tos were taken, a rogue pilfered the
main rotor mast, supporting struc­
ture, and the all-important rotor
head and pre-rotator mechanism,
forcing the Autogiro's storage inside
a hangar. Ted still intended to re­
store the aircraft to flying condition,
but without the heart of the aircraft,
it proved to be a long-term stor­
age situation. While he never got a
chance to restore it, Ted Sowirka's
dedication to keeping the project
as intact as possible saved it for the
next generation of restorers.
By 1996, the registration of the
aircraft has been allowed to lapse,
and the N number has been assigned
to a Cessna 172 made in 1973. Ted
had attempted to get the aircraft re­
registered, noting in a letter to the
agency dated July 1996 that

The other obviously critical items
were the main rotor blades. Each
of the blades, as can be seen in the
photos accompanying this article,
are built like a very high-aspect ra­
tio wing, with a steel tube spar, over
which are fitted tightly spaced wood
ribs, with plywood leading edges and
stainless steel trailing edges. One un-
usual aspect to their construction is
the requirement for slip joints in the
trailing edge of each blade, neces­
sary since the blades flex significantly
in flight. This flexing is important,
soaking up both flight and structural
loads spanwise along the blades as
each blade Circumnavigates the ro­
tor arc 140 times per minute, just a
little faster than twice each second.
The rotor blades that had been re­
tained with the project were in rough
shape, but the spars were usable, al­
lowing the restorers to build up not
only the ribs (all 216 for a set of four
blades, thank goodness for CNC mill­
ing machines!), but they had enough
information and parts to create a new
replacement set of rotor blades, and
are confident that their "rotor shop"
can handle their maintenance needs
for years to come.
The rest of the rotorcraft's restora­
tion was pretty straightforward, with
the standard repairs being made to a
70-plus-year-old airframe. While the
stub wings were intact, they were re­
built almost completely, built up en­
tirely of wood. The fuselage needed a
bit of steel tubing replaced, and while
we' ll get a bit ahead of the story a bit
here, one little bit of clever engineer­
ing deserves to be highlighted. During
the flight-testing phase of the restored
Pitcairn, a series of mistakes resulted
in a main rotor blade or two, or three,
contacting the top of the vertical fin. It
promptly folded over to the side, with
no damage done to the tail post or the
rest of the fuselage. (You'll get a chance
to read more about the incident in the
upcoming January 2010 issue of EAA
Sport Aviation, in the feature article on
the PA-18 written by Andrew King.)
Once repairs were started, the rea­
son why the fin folded so neatly be­
came apparent. Pitcairn's engineers,
realizing that it was likely that a com­
bination of surface winds, low-rotor
rpm, and taxiing on the ground could
result in a rotor strike in the fin, sim­
ply had a set of holes drilled in the tail
post, creating a weaker spot on the
tube just above the top of the fuse­
lage. Whack it with a rotor blade, and
voila, the fin flips to the side, damage
is minimal to the fuselage, and if you
were a lucky owner back then, you
could call up the factory and order up
a new fin. If you're a restorer, you get
to break out your jig and torch and
build up a new one yourself!

who had flown his own PCA-2 across
the United States a full two weeks
before Amelia Earhart's flight in the
Beech-Nut gum-sponsored PCA-2, had
been regularly consulted about flying
the Autogiro by Andrew King, who
was slated to be the Pitcairn's pilot.
Johnny died on June 24, 2008, within

Steve Pitcairn wipes down Miss Champion
after arrival at Oshkosh '86.
But few aircraft caught and held
the public attention as did the Au­
togiro. Called "flying windmills"
by news reporters who had little
understanding of the principles of
autorotational flight, these strange­
looking aircraft, invented by a
Spanish engineer named Juan de
la Cierva, captured the hearts and
minds of the air-minded public be­
cause of their remarkable perfor­
mance coupled with a high degree
of safety. These facts made Auto­
giros an ideal means to carry out
nationwide advertising campaigns
by a number of American manufac­
turers. The Champion Spark Plug
Company was one of these.
Champion executives were not
slow to see the large amount of
publicity Autogiros drew wherever
they performed across the country.
Nor was the fact that many of the
leaders of American aviation, such
as Charles Lindbergh, Jimmy Doo­
little, Frank Hawks, Amelia Earhart,
Clarence Chamberlin, David In­
galls, and many others, were beat­
ing a steady path to Pitcairn Field
near Willow Grove, Pennsylvania,
where Harold Pitcairn was design­
ing and building these phenome­
nal aircraft.
It wasn't long before Champion
Vice President M.e. Dewitt showed
up at the Pitcairn Aircraft Com­
pany office prepared to do busi­
ness. Pitcairn Vice President Edwin
Asplundh promptly led Dewitt out
to the ramp in front of the main
hangar doors where stood an Au­
togiro with its engine idling. In the
rear cockpit sat Jim Ray, Pitcairn's
chief test pilot, who motioned De­
witt to climb into the front seat.
As soon as Dewitt's safety belt was
fastened, Jim engaged the clutch,
bringing the rotor up to flight
speed, and executed a short, steep
takeoff within the confines of the
fenced-in ramp area.
The demonstration of the Au­
togiro's characteristics to which
Jim treated Dewitt included the
usual aerial maneuvers and then
a throttled-back pass at the field
a mere 15 feet above the grass at
a speed of less than 30 miles per
hour, yet under complete control,
and finally a vertical dead-stick
landing from 500 feet on the exact
spot from where they had departed
10 minutes earlier, with a roll of
only 2 or 3 feet. Dewitt, who was
no stranger to flying, climbed out
on the wing as soon as the engine
stopped, and with a big grin on his
face said, "I'm impressed, but can
our pilot do that?" "Who is your
pilot?" Jim asked. "Capt. Lewis A.
Yancey, if he can handle it," re­
plied Dewitt. "I know Yancey,"
said Jim. "He'll do fine."
As a matter of fact, "Lon" Yancey,
famed for his trans-Atlantic flight
in a Bellanca in 1929 to Rome, it­
aly, had already been receiving Au­
togiro flight instruction from Jim
and "Skipper" Lukens, another Pit­
cairn pilot, for several days. His
handling of the Autogiro was quite
acceptable. With more experience
he became an accomplished Au­
togiro pilot with the capability of
handling the routines Autogiro
demonstrations called for.
Satisfied, Dewitt signed the sales

Tour. Two days after the Autogi­

ro's delivery at Toledo, Ohio, Capt.
Yancey took off from Ford Airport
with the 1931 National Air Tour.
The Champion Autogiro was the
official tour ship . During the tour,
Miss Champion visited 21 states and
38 cities and towns from London,
Ontario, Canada, to New Orleans,
Louisiana, and from Fort Worth,
Texas, to Kalamazoo, Michigan.
Total mileage was well in excess of
6,500 with her flight log showing
more than 120 hours aloft. Every­
where the Autogiro landed it at­
tracted wide attention, and easily
won the major share of newspaper
and radio coverage, a fact that visi­
bly annoyed a number of the other
pilots on the tour.
After the air tour, the Champion
company put Miss Champion to
work getting publicity for Cham­
pion dealers from Maine to Florida.
Her demonstrations of controlled
slow flight, unusual maneuverabil­
ity, and near vertical landings at the
annual National Air Races brought
national recognition to this new
and safer form of flight.
In January of 1932, Miss Cham­
pion made a flight considered
"risky" for any aircraft, let alone
an Autogiro. Until then no Auto­
giro had ever flown more than 25
miles over water. On January 24,
Capt. Yancey flew the Autogiro
from Miami to Havana, Cuba, a
distance of more than 300 miles.
His arrival in Havana was greeted
by enthusiastic crowds, and he was
invited to the presidential palace
by President Machado.
But Yancey had even greater am­
bitions. A wire to the Pitcairn Auto­
giro Company brought him a week
later a specially designed auxiliary
fuel tank that he mounted in the
front cockpit of his PCA-2, thus
doubling his fuel supply. He then
successfully began his most miracu­
lous flight of all from Havana, over
the Cuban wilderness, across the
wide and treacherous waters of the
Yucatan Channel (part of the Gulf
of Mexico), and over the trackless
expanse of the Yucatan jungles to
its capital of Merida, a nonstop trip
of nearly 500 miles, where he was
welcomed by the governor.
It was from the ancient city of
Merida that Capt. Yancey made a
number of flights to the capital of
the Mayan Empire at Chichen Itza,
even landing in front of the famed
Temple of the Serpents-the great
Mayan pyramid. The ability of Miss
Champion to fly slowly and even
"hover" over certain spots helped
the archeologists make new discov­
eries that could have taken years
on the ground. Back in the United
States, subsequent flights into the
Yosemite Valley in California and
the crater of Crater Lake, Oregon,
were a piece of cake by comparison.
Miss Champion was not just a
curiosity of her era. Wherever she
flew she engendered confidence in

An interested audience poses with Miss Champion at the Temple ofTigers, Yu­

the method of flight as a truly safe
form of aerial navigation. She was
a hard worker, too, often towing
advertising banners over the cities
she visited, attracting valuable at­
tention to the products her banner
proclaimed. The Champion com­
pany declared in a letter to Pitcairn
Aircraft, the builder of its Autogiro,
that the value of the aircraft in in­
creasing sales and goodwill toward
its products was beyond estimate.
Miss Champion was one of the
first of her type to appear in the
United States and was retired from
active service, after setting a new
altitude record on September 25 ,
1932, of 21,500 feet, the highest a
rotary-wing aircraft had ever flown .
In her way, Miss Champion had
been a missionary, her clumsy ap­
pearance appealing to the imagi­
nation of the public and winning
its confidence through her ability
to deliver the goods with complete
safety. She was retired with honor
as a permanent exhibit of Chicago's
Rosenwald Museum of Science and
Industry in the spring of 1935.
After World War II, the museum
had to give up Miss Champion in fa­
vor of more timely exhibits from
the recent world conflict, and this
vintage lady was released into the
knowledgeable care of A.K. Miller
of Montclair, New Jersey, who kept
her in his own museum for many
years until he was forced to close it
down and move to other quarters.
Miller couldn't bear the thought of
giving up this magnificent relic of
the pioneering era in American avi­
ation, so he disassembled her and
moved her into a barn on his farm
in Vermont, where she gathered
dust for many years.
Meanwhile, Stephen Pitcairn,
(EAA 109260, VAA 4080), son of
Harold Pitcairn, the aviation pi­
oneer and winner of the Collier
Trophy for his development of
the Autogiro in this country, had
begun the formidable task of col­
lecting and restoring examples of
his father's aircraft . The first to be
completed by Steve was the PA-5
Mailwing, originally built for his
VINTAGE AIRPLANE
19
father in 1928. Next was a PA-7
Sport Mailwing, which won for
Steve the Silver Age Champion
Award at the 1983 EAA convention
at Oshkosh, Wisconsin.
Somewhere along the line Steve
heard about the autogiro owned by
A.K. Miller. After several attempts
to communicate by mail, Steve
went to Vermont to visit Miller,
who was then in his 70s, and fi­
nally succeeded in negotiating for
the PCA-2 Autogiro, NCl1609,
some five years later. Steve had it
trucked to his hangar at the Tren­
ton-Robbinsville Airport, New Jer­
sey, where the restoration process
began in October 1982.
Fortunately, at this time, George
Townson (EAA 251901, VAA 9519)
of Delran, New Jersey, a former
Autogiro pilot and mechanic, was
available for a full-time commit­
ment. George's impressive cre­
dentials include airframe and
powerplant certificate with an in­
spection authorization and ground
instructor certificate with most rat­
ings . He holds a commercial fixed­
wing ticket and helicopter and
Autogiro ratings along with flight
instruction ratings for these types.
He is an accomplished "practical
20
NOVEMBER 2009
engineer." He is a member of the
Society of Experimental Test Pilots,
making "first flights in several ex­
perimental rotorcraft in the 1940s,
including the 'world's largest'" (Pi­
asecki XHRP-1, tandem rotor) he­
licopter. He built, from scratch, a
small racing plane and a light, tan­
dem rotor helicopter.
Before joining Stephen Pitcairn
he had been chief inspector and
director of engineering for a re­
gional air carrier. Under his super­
vision, Miss Champion was stripped
of her original cover (the logos and
numerals were saved to be cop­
ied) , and the painstaking process
of inspection began. Careful nota­
tion of items to be worked on were
listed in order of priority. Eighty­
five percent of the original parts
were refurbished and reinstalled,
but a few items had to be remanu­
factured, since replacement parts
did not exist. Fortunately the origi­
nal Pitcairn factory drawings were
in Steve's possession.
One of the most important tasks
in the restoration process was the
rebuilding of the rotor blades. Each
main spar had to undergo rigid X­
ray inspection to make sure there
was no corrosion or cracks in the
steel tubes that served as the back­
bone of these rotating wings. Then
each rib with its spar-attachment
collar had to be inspected and very
often replaced because of damage,
cracks, or other defects.
It was during this tedious but
crucial part of the job that George
noticed that the airfoil ·curve of
the ribs actually used in the rotor
blades was slightly different from
the curve called for by the Pitcairn
engineering specifications. Accord­
ing to this official document, the
airfoil used was the Goettingen
429. But when George placed one
of the ribs he had removed over
the official drawing, he saw im­
mediately that the curve was just
slightly different.
Methodically he checked each
rib throughout the length of the
spar but found the same small but
definite difference. Had someone
made them all wrong, or was this a
planned departure from the origi­
nal specs? Knowing the care with
which the Pitcairn people did their
jobs, he reasoned that it was more
likely that this was a deliberate de­
sign modification. He reached for
the phone and called Carl Gun­
ther, the Pitcairn archivist, and af­
ter briefly outlining the problem,
asked him if he knew of anything
in the old Autogiro company re­
cords that would confirm or deny
his suspicions.
Requests of this kind were not
new to Gunther, who had presided
over the records for more than 15
years. As a matter of fact he had just
recently set aside several engineer­
ing reports that he thought might
be helpful to Steve Pitcairn and his
able restoration chief, and in one of
them he recalled seeing some state­
ments made by Paul Stanley, one of
the Autogiro company's key engi­
neers, about the design of the rotor
blades used in the PCA-2 Autogiros.
Within a few days, George was
holding in his hands the docu­
ments that confirmed his belief
that this was a deliberate design
modification. The new airfoil
proved on testing to be smoother
and more efficient under flight
conditions, but the changes, com­
ing on top of so many others as the
Pitcairn team pioneered its way to
new horizons of knowledge, rated
only a single sentence reference
in the official engineering report.
That sentence, however, enabled
George to properly rebuild the four
rotor blades that allowed this un­
usual old bird to fly.
Airfoils, critical as they were,
proved to be only one of the fac­
tors necessary to the solution of
the rotor problem. Each blade
had to be accurately weighed and
their weights brought to within 2
ounces of each other, and at the
same time the spanwise center of
gravity of all blades had to be kept
within 1/8 inch of each other. In­
attention to these details could
cause, at least, an uncomfortable
ride from vibrations.
Finally, in the spring of 1985,
Miss Champion was rolled out of
the hangar to check her engine
and rotor system. As Steve Pit­
cairn climbed into the cockpit
to begin this initial testing pro­
cedure, George Townson looked
on somewhat apprehensively.
Steve activated the starter for the
nine-cylinder J-6 Wright engine.
The ground-adjustable Hamilton
Standard propeller swung jerk­
ily a couple of times and, as the
engine rumbled into a throaty
roar, spun into a full shiny disc
of whirling blades, blowing swirls
of dust behind the Autogiro's up­
turned elevators.
Satisfied that all was well so far,
Steve looked over at George, who
gave a little shrug of his shoulders
and made a whirling sign with his
forefinger. Steve reached for the
rotor clutch knob and pulled it
firmly toward him to its lock posi­
tion. Slowly the four large overhead
blades began their counterclock­
wise spin. Gradually Steve eased
open the throttle, and the rotor in­
creased the speed of its rotation.
Soon the blades were standing
straight out at right angles to the
hub. Both men were looking for
signs of increasing vibration that
would indicate some problem with
the rotor. George noticed that one
of the blades seemed to be track­
ing a bit lower than the others,
so he gave Steve the sign to cut
power to the engine. As it slowed to
idling speed and the rotor gradually
slowed down, George walked over
and told Steve to shut her down so
he could check the blade settings.
It was while this checking was
going on that a small wrench be­
ing used to adjust one of the blades
near its root fell and punctured a
hole in the fabric on the wing be­
low. Now a small wrench is not
a heavy object, and both men
thought it strange that a puncture
would result from this trivial event.
George went to his toolbox and
brought back a Maule fabric tester.
Testing the area near the puncture,
he found it below allowable toler­
ance. He then tested other areas
on the fabric-covered aircraft. With
only slight variations the result was
the same. The brand new fabric
covering was definitely weak and
would have to be replaced! What a
disappointment, because it meant,
among other things, that the Au­
togiro would miss EAA Oshkosh
1985, just one month away.
Although the fabric tested low,
Steve and George decided to make
three short test flights to 700 feet
to check the systems, rotor rpm in
flight, and control response, etc.
These short flights, the first in 51
years for Miss Champion, proved the
excellence of the original design
and the painstaking care George
gave to the restoration. All systems
worked above expectations.
To determine the cause of the
fabric deterioration, samples were
sent to a testing laboratory, along
with a description of what had
happened. When the report came
VINTAGE AIRPLANE

back it indicated the particular ni­
trate dope formulation had an ex­
cess acid condition that resulted in
the serious weakening of the Grade
A cotton fabric. The process of re­
covering and painting Miss Cham­
pion with a new covering system
was started in September 1985.
Off to Oshkosh '86
Steve would not be denied fly­
ing his rare Pitcairn Autogiro to
Oshkosh '86; however, the trip
wasn't certain until the last min­
ute. Having only a total of four
hours on the plane, he departed
on Thursday, July 31, hoping to ar­
rive at Oshkosh August I, opening
day of the EAA convention.
He battled inclement weather
associated with a warm front until
crossing the Allegheny Mountains
when things began to clear up.
The first leg of his flight was one
hour 45 minutes to a refueling stop
at Carlisle, Pennsylvania, where he
would also check his calculated fuel
consumption. There he landed into
the wind across the runway utiliz­
ing the short takeoff and landing
characteristics of the Autogiro. Al­
though the plane carries 52 gallons
of fuel, Steve planned his cross­
22 NOVEMBER 2009
country legs at a conservative max­
imum of 2 hours 15 minutes.
His next stop was Beaver County
Airport, northwest of Pittsburgh,
and from there he flew to Bluffton,
Ohio (between Lima and Findlay).
Unbeknownst to Steve at the time,
a nut had loosened, allowing the
oleo strut on the left landing gear
to separate. The wheel and its "vee"
axle were dangling from the N­
strut, and although Steve was talk­
ing on UNICOM with the folks at
Bluffton, they didn't recognize the
problem, as they had never seen an
Autogiro before.
The touchdown on the run­
way was on the side of the er­
rant left wheel at an estimated 8
mph groundspeed. The plane piv­
oted to the left, going down on
the left wing, but fortunately not
far enough to ding the ground­
adjustable Hamilton Standard
propeller. Due to centrifugal
force holding them out, the rotor
blades didn't contact the runway
until they slowed and were sus­
pended by their respective droop
cables. Only the rotor blade tips
touched very lightly, doing mini­
mal damage.
The airport owner and manager,
Harold Carey came out on his golf
cart, sized up the situation, and said
he'd call the wrecker from town to
hoist the plane and move it off the
runway. This was accomplished, and
it was moved into a hangar where
it rested on some barrels while the
landing gear was repaired.
Steve contacted George Town­
son back home, and he came to
Bluffton to supervise the repair job.
Thanks to the assistance of some
local folks and the availability of a
machine shop and welding facili­
ties, the repairs were completed. In
the meantime, Steve's good friends
Wayne Hays and his wife of Rob­
binsville, New Jersey, left three days
early on their vacation and brought
to Bluffton the needed materials
from Steve's hangar, including cov­
ering material, paint, and an extra
set of streamline wires that had to
be replaced between the two land­
ing gear N-struts.
Wayne worked all the next day
(Saturday) patching and painting
the wing and rotor blades, and
by that evening, Miss Champion
was ready for a test flight . Every­
thing checked out okay, and Steve

n the last issue we looked in detail at structural
and nonstructural metallic components of older
aircraft. Now, let's look at other materials and pro­
cesses that will be helpful in restoring and main­
taining our vintage aircraft.
I
Control Cable: Aircraft quality control cable is
available in sizes from 1/16 to 3/8 inch in diameter. For
most vintage airplanes, the maxi­
mum diameter used is 5/32 inch.
Two types of material are used
to manufacture cable-stainless
steel and carbon steel (which is
coated with pure tin or zinc for
corrosion protection). Either flex­
ible or nonflexible type cable may
have been used on th e original
airplane. I suggest you use the
type of cable originally installed;
however, I have substituted cor­
rosion-resistant cable for carbon
steel, especially where cables are
subjected to the elements and
corrosion is a problem.
Incidentally, researching the
history of cable invention and
production is very interesting.
On this subject one person's
name comes to the forefrontJohn Roebling, one of the pioneers of the wire rope industry. Interesting reading can
be found at the following websites:
www.InventionFactory.com/history/RHAgen/rstory/
rswar.html
www.globalspec.com/FeaturedProducts/Detail/Loo­

Roebling/40136/0
Flexible cables may have been used by the factory
when the cable is not required to change direction
drastically. Flexible cable is designated as 7x7. It is
composed of wire rope of six strands of seven wires
each, twisted and laid around a strand center or core
consisting of seven wires.
Extra-flexible cables are designated as 7x19. That is
wire rope of six strands laid around the central core
strand in a clockwise direction. Each strand consists
of 19 wires each. Cable strength data can be found
in FAA AC 43.13-1B, Section 8.
Cable strength data will not be
presented here. After fabrication,
control cables are tested to a proof
load, which is a pull test to 60
percent of rated cable strength for
three minutes.
Cable assemblies are me­
chanically fabricated, the most
common being swage-type ter­
minals and the Nicopress pro­
cess. The Nicopress-type cable
ends may be used as a substitu­
tion for the Navy five-tuck wo­
ven ends used on most vintage
aircraft. The Nicopress process
is most easily adapted for "field"
manufacture of cables. Swage
cable end fittings require elabo­
rate squeezing tooling, which is
hard to find and very expensive.
It's interesting to note that the
newly revised AC 43.13-1B manual has deleted both
the wrapped and soldered and five-tuck woven cable
ends. However, both these deleted methods appear
in the terminated AC 43.13-1A. When I attended
Northrop Institute of Technology back in 1960-1961
to train for my airframe and powerplant (A&P) certifi­
cate, we were required to fabricate a five-tuck cable to
length. We made a cable clamp and marlin spike from
scratch out of raw stock, learning how to use hand

tools and read blueprints. I still have those tools to
this day, although they are a little rusted.
Inspection of control cables should be made at the
100-hour and annual inspections. Most cable wear takes
place where the cables pass over a pulley or through a
fair-lead. To locate broken wire(s) in a strand, run a rag
along the cable. In many cases the cable should be loos­
ened so a close inspection can be made of the area that
touches a pulley through full travel. Bending the cable
so that the portion that rubs on a pulley is on the out­
side of the bend will help reveal damage.
Corrosion is another common type of damage. It
will show up on carbon steel cables as rust. Replace any
cable that shows signs of damage. Again, A C43.13-1B
is a good guide for cable inspection. Figure 1 shows the
method of detecting broken cable strands, particularly
where cable lays contact a pulley.
Figure 1
Inspect pulleys for wear and ensure that pulleys ro­
tate when cable is moved.
Always lube pulleys with a good lubricating oil. Re­
place any pulleys that show signs of wear or seizing of
the bearing or bushing. Sudden loss of cable tension
can usually be traced to the cable wearing into a pulley.
Inspect cable ends for wear or slippage. Swage-type
cable ends are painted red at the junction of the termi­
nal end and cable so slippage can be detected. Again,
a sudden loss of cable tension should be investigated
immediately. Don't just retension the cable.
Finally, turnbuckles are used in a cable system to
provide a means of tensioning. They actually adjust
the length of the cable. Cable tension on vintage air­
craft is relatively small, from 10 to 25 pounds. The rea­
son is the pulleys did not have a bearing in the center,
just a bronze bushing. The more tension on a cable,
the "heavier" the control movement. Adjust tension to
give good control response and safety the turnbuckles.
I have found that 10-20 pounds of tension is good for
these type systems.
When installing turnbuckles it is necessary to screw
both threaded terminals into the turnbuckle barrel an
equal amount. It is essential that cable terminals be
screwed into the barrel so that not more than three
threads on the terminal are exposed. Be sure to secure
both cable terminal ends when screwing a turnbuckle;
don't allow cable to twist during this operation.
There are two methods of safety wiring turnbuck­
les-single and double wrap. The correct method
for wrapping turnbuckles is shown in AC 43.13-1B,
Figure 7-24. Pay close attention that the correct size
safety wire be used when safetying cable terminals.
This is a most common area where mistakes are made.
AC 43.13-1B gives appropriate wire type and diam­
eter for this process. Either copper, brass, stainless
steel, monel, or K monel may be used. NOTE: One­
sixteenth-inch and 3/32-inch cables may be single
wrapped only with copper, brass, or stainless steel
safety wire at least 0.040 inch in diameter. For cables
of lI8-inch diameter, single-wrap safeties are made
with 0.040-inch stainless steel safety wire . If a single­
wrap safety using copper/brass wire is desired, the
diameter must be 0.057 inch. I've never used or seen
0.057-inch brass wire! However, lI8-inch cables may
be double wrapped and safetied with copper/brass or
stainless steel wire. UNDER NO CIRCUMSTANCES
SHOULD 0.032-INCH DIAMETER WIRE BE
USED TO SAFETY ANY TURNBUCKLE. It might
be wise to do a turnbuckle safety wire check of your
airplane. Figure 2 shows both single- and double­
wrap safety of turnbuckle.
Only cable terminal ends and fittings that meet
AN standards should be used in aircraft applications .
AC 43.13-1B gives directions on how to properly
safety a turnbuckle.
And lastly, cables tend to stretch after fabrication,
and it may be necessary to retension the cables after a
few hours of flight. When retensioning cables, always
make the same adjustment to cables that pull against
each other. In other words, if the aileron system has
three turnbuckles, adjust all three the same amount of
turns, and the travel will not be affected; only the ten­
sion will increase.
Tubing: Aluminum tubing is commonly used
to fabricate fuel, oil, hydraulic, and instrument sys­
tem installations. Alloy 3003 is most easily bent and
flared, followed by 5052, and finally 6061. Since most
vintage restorations require hand-forming and flar­
ing, only these alloys should be considered. In the
softest state the code will be an "0," indicating the
annealed condition. An example would be 5052-0.
Alloy 6061 would show a hardness code of -T6 (6061­
T6), indicating the tube has been heat-treated and ar­
tifiCially aged. It is difficult to bend and flare this tube
type, but not impossible.
VINTAGE AIRPLANE
25
(D) SINGLE WRAP (B) DOUBLE WRAP
Figure 2
Tube Bending: Alloy 3003-0 tube can be hand­
bent, even small radius bends. This tubing should be
used for instrument installations where the pressure is
low and tubing is protected. Alloy 5052-0 tubing can
be hand -bent, but the bend radius must be large to
prevent flattening or kinking of the tube in the bend
radius. Use of hand-bending tools is recommended.
Alloy 6061-T6 can only be bent with a hand-bending
tool using a substantial bend radius. Always check tube
flattening in the bend radius; for fuel lines the maxi­
mum flattening is 5 percent of tube diameter.
Tube Flaring: Aircraft tubing is flared to an angle
of 37 degrees. Do not use automotive flaring equip­
ment, as the flare angle is 45 degrees. The older aircraft
used AC fittings. While the flare angle is the same, AC
fittings are not interchangeable with AN fittings. Most
modern restorations will convert fittings to AN due
to ease of procurement. Tubing should be flared so as
much of the flared area of the tube as possible seats on
the AN fitting. Always check flared area for cracks, par­
ticularly alloy 6061-T6 tubes.
Alignment of tube to fitting is also critical. Misalign­
ment will eventually cause leaks at the fitting.
Tube Installations: For instrument installa­
tions, use 3003-0 tubing, 1I8-inch (-2) or 3/16­
inch (-3) diameter. Some restorers may want to use
5052-0 tube for oil the pressure gauge. For fuel in­
stallations, use 5052-0 tubing, most often Vz-inch
(-8) diameter. AC 43 .13-1B gives much information
on fuel systems, particularly the location of support
clamps and fuel line bonding information. Consult
Chapter 8, Section 2.
I don't like using copper tube in aircraft applications
because it will work-harden with vibration . I know all
early aircraft used it for fuel and instrument installa­
tions, so if authenticity is the goal, use it. However,
copper tubing may need annealing from time to time.

building the Spirit of St. Louis; he required the interruption
of the fuel lines with sections offlexible nlbber hose to soak
up vibration and prevent breaks due to work-hardening of
the tubing material.-H.G. Frautschy)
Tube Fittings: The most common tube fittings
are the AN818 nut and AN819 sleeve. Most aviation
supply company catalogs give a list with description
of all AN fittings needed to complete the project. I
keep a copy of the Standard Aircraft Handbook in my
toolbox for quick reference of the AN code. Since I'm
writing this in Florida, a nearby source for this handy
book is www.Great-Atlanticl.com. Look for part number
TS157642-8. Most suppliers carry this book; you'll find
it very useful.
Low-Pressure Oil System: Dry sump oil systems
use tubing of 1 inch in diameter. The tube can be 5052­
0, and special tools are required to bend it to the de­
sired shape. After bending, the tube is beaded on both
ends using a beading tool. Be sure to remove all burrs
after beading, and clean the tube before installation.
Tube Installation: After fabrication of necessary
tubing, be sure to clean thoroughly and blow-dry with
compressed air. Assemble with proper hose and clamp
using stainless steel hose clamps. The tube ends should
never touch, as this would allow fragments of alumi­
num to enter the oil system. Maximum distance be­
tween tube ends is one tube diameter.
Hose: For fuel and oil systems use only Mil-H-6000
hose. It will come in inside diameter sizes, -4 (1/4 inch)
through -112 (lVz inches). The burst pressure for this
type hose is 1,000 psi, and it is resistant to fuel, oil,
and coolants. For pitot/static instrument systems I
have used rubber heater hose or Tygon B-44 type flex­
ible plastic tube, but not in antique restorations. For
fuel and oil systems I use stainless steel hose clamps.
Tighten clamps to torque of just 20 inch-pounds and
don't over-tighten.
That's it from here. Let's keep those antiques safe
and flying!

THE MUMMERT COOTIE McRAE EAA 93 BY JACK
mmediately after World War I,
Harvey Mummert was one
of the earliest designers and
builders of homebuilt air­
planes. His several original­
design lightplanes were built in
his spare time with the help of
friends, while he was employed as
an engineer for the Curtiss com­
pany at its Garden City, Long Is­
land, plant. All his airplanes in­
corporated advanced features and
showed skillful application of ex­
cellent design, both aerodynamic
and structural.
Mummert's first lightplane ap­
peared in 1921, after two years
I
of work, and was a very attrac­
tive miniature biplane called the
Baby Vamp, which soon came to
be known as the Cootie. The first
flight of the Cootie was made on
July 8, 1921, by the well-known
pilot Bert Acosta. Some diffi­
culty was encountered before the
flight when it was discovered that
Acosta had to remove his shoes in
order to get his feet through small
holes in a bulkhead to operate the
rudder bar.
On the first flight the pilot
reportedly held the ship on the
ground for 200 feet before taking
off. When it got off the ground it
was seen to be flying very steadily
and at a speed estimated to be
nearly 100 mph. Acosta, who was
noted for his fondness for aero­
batics, proceeded to put the little
biplane through an Immelmann
and many other maneuvers,
reaching 1,500 feet altitude with­
out any difficulty. After 15 min­
utes of flying he landed smoothly
and reported that liThe machine
has absolutely no tricks and needs
very few minor adjustments."
The engine used in the Cootie
was reported to be a 25-hp Law­
rance, which would imply that it
was a surplus Type A engine, as

of the Cootie photographs indicate
that this was not the case, and that
the engine was the relatively rare
Lawrance N model, of which only
a few were built for the U.S. Navy.
The Type N engine had the in­

valve pushrods at the rear, the op­
posite of that for the Type A used
in the Penguin s. The N engine
also had advanced features, such
as dual ignition supplied by a bat­
tery, dua l carburetors, and a gear
drive to the propeller. Its weight
was only 79 pounds and its width
was much smaller than the Type A.
Its displacement was 120.58 cubic

inches, and it developed 40 hp at
1900 rpm, although it was stated
that the engine speed was limited
to 1500 rpm during the flight test.
The N engine had one bad feature
of the Type A, however, in that it
still had the single-throw crank­
shaft, which caused severe vibra­
tion and, in one case, reportedly
shook a carburetor off in flight. It
is assumed that Mummert's posi­
tion in the Curtiss engineering de­
partment gave him access to this
unusual engine.
At that time, Curtiss had just
started building its famous series
of racers using wooden mono­
coque fuselage construction with
plywood-covered wings. The Coo­
tie u sed these same features, the
fuselage being built of three lay­
ers of veneer strips at 45 degrees
to each other, wrapped around
a wooden form and glued, after
which the form was removed and
bulkheads installed where neces­
sary. The tail surfaces were also all
wood, including the covering.
The wings, which used th e
R.A.F. 15 airfoil , were each built
as a single unit with no dihedral.
Each wing used nine spars between
the leading and trailing edges. The
spars were of rectangular section,
l,4 -inch wide, and varied in depth
according to their chord wise lo­
cation. The maximum thickness
of the wing was only 2 inches.
The upper rear main spar and the
lower front main spar were of the
box type, since they made up part
of the wing truss and had to re­
sist axial loads due to the flying
and landing wires. Mahogany ply­
wood 1/16-inch thick was used to
cover the wings. This type of con­
struction gave a smooth, stream­
line shape of great rigidity. The in­
terplane struts were of streamline
steel tubing, and the upper wing
was supported by two cantilever
struts at the center of the wing.
The flying wires consisted of a
pair of streamline wires on each
side, running from the fuselage at
the lower front spar to the upper
rear spar at the interplane strut
fitting. The landing wires were a
single wire on each side of the air­
plane running from th e lower end
of the front interplane strut to the
top of the rear cabane strut.
Appa rently, afte r flight testing,
two add itional wires were added
on each side, extendin g from the
rear upper and lower interplane
stru t fi ttings to the fi rewa ll bulk­
h ead, ju st aft of th e en gine. The
reason for these additi onal wires
is n ot kn own, but they m ay have
been added in an att em pt to ab­
sorb some of the engine vi bration,
or possi bl y to re d uce th e effect
of defl ection of the cantilever ca­
ban e struts under unsym metrica l
wing loads.
Ailerons we re ins tall ed on the
lower wi n gs only, and ex t ended
for t he full wing span. Th e aile­
rons were controlled by a horn at
the airplane centerli n e inside t h e
fuselage with no external fittings.
Th e fin , of u p p e r and lower
sect ion s, was built integral with
th e fu sela ge, an d th e t a il skid
was attached to its lower section.

Harvey C. Mummert: Pilot, Designer, and Manufacturer
Harvey C. Mummert was born in Alliance, Ohio,
on April 4, 1892. He graduated from Mount Union
College, Alliance, and the Case School of Applied
Science in Cleveland.
In 1916 he started work for the Curtiss company
in Buffalo as an engineer, and his signature appears
on some 1916 IN-4 drawings. He apparently made
good as an engineer, and in 1918 he was transferred
to the Curtiss Experimental Engineering plant in Gar­
den City, Long Island. Here he had responsible posi­
tions in the design and development of the MF Fly­
ing Boat and the Eagle eight-passenger tri-motored
biplane in 1919, the twin-engined CJ. NavalTorpedo
monoplane, the PW-8 fighter, and asmall all-metal
seaplane glider designed for the use of Glenn Curtiss.
Harvey Mummert
One of his co-workers describes Mummert as "Avery
mild mannered man with an unusually keen mind and asense of sound practical design:'
Since his days in high school he had been interested in small airplanes, and in the 1921-24 period he
designed and built, in his spare time, three successfullightplanes. These were the 1921 (ootie biplane
with aLawrance engine, the 1923 midwing monoplane of wood monocoque construction using a
Harley-Davidson motorcycle engine, and in 1924 an all-wood low-wing cantilever monoplane, also
Harley-powered, which competed in the 1924 and 1925 National Air Races.Mummert was amember of
the Curtiss Flying Club atthis time, and in 1924 he received Federation Aeronautique Internationale (FAil
"Aviation Pilot's"License No. 6169. In 1927 he received Transport Pilot License No. 550.
In 1924 Mummert left Curtiss and became chief engineer for the newly reorganized Mercury Aircraft
Inc. of Hammondsport, New York. During the next 15 years at the Mercury company, Mummert was
responsible for anumber of interesting deSigns, as follows:
1924 - Mercury St. Liberty-powered biplane, awinner of Mail Plane competition held by the Post
Office Department.
1925 - Redesigned Standard J-1to five-seater, C-6A-powered, and as atwo-place trainer. Five sold
to Argentine government.
1925 - Mercury Jr.two-place utility biplane, C-6A engine. Flown by Mummert in 1925 National Air
Races and in the 1925, 1926, and 1927 Ford Airplane Reliability Tours, placing third in 1927.
1926 - TC-11 nonrigid training blimp delivered to Army in 1928.
1927 - Mercury Kitten two-place cabin monoplane of all-steel tube construction. Originally powered
by Mummert-designed two-cycle, four-cylinder opposed-piston engine, later with Warner Scarab.
1929 - Schroeder Wentworth Safety Plane for Guggenheim Safety Competition. Crashed during
qualifying flights.
1929 - Mercury Chic T-2 primary trainer. Approximately 20 built. Flown by Mummert in Ford Na­
tional Air Tours, 1930 and 1931 .
1930 - Mercury S. Racer. Flown by Mummert in 1930 All-American Flying Derby, a5,540-mile race.
1931 - Mercury S-1 Racer. Steel tube geodetic construction. Flown by Mummert in National Air
Races and other local air shows.
1938 - Mercury Chic modified and entered in Air Corps Primary Trainer competition at Wright Field.
In 1939, after ashort illness, Mummert died at the age of 47. He had been aprolific, innovative
designer with astrong competitive spirit as demonstrated by his many entries in air races and air tours
flying airplanes of his own design.

VINTAGE AIRP L ANE
31
BY DOUG STEWART
All available info
s I was departing the pat­
tern of my home base
airport a few days ago,
heading out to the prac­
tice area to do some air work with
a client in my PA-12, I overheard
a pilot announce that he was 10
miles out to the southwest and in­
bound for landing. Hearing that, I
knew that I would have to be es­
pecially diligent in my "see and
avoid" collision avoidance scan, as
I was headed to the south myself.
But the next thing the pilot said
increased my concern. He asked:
"Uh ... which runway you using
at Columbia County?" Since I
had just announced not only the
runway I was departing on, but
further, the direction of my depar­
ture, and since there were several
other planes in the pattern, all
making proper announcements of
what they were doing, I couldn't
help but wonder if this inbound
pilot was using his ears as well as
his mouth.
As the communications con­
tinued, my concern increased.
His next communication asked
which way the wind was blowing.
As there is an automated weather
observing system (AWOS) at the
airport, it was obvious that this
inbound pilot had not spent the
time listening to it to find out all
the pertinent information relative
to the ceiling, visibility, wind, and
barometric pressure. At this point
I decided to alter my course to the
southeast and increase my vigi­
lance out the window.
A
32
NOVEMBER 2009
Within a minute or two the in­
bound pilot now asked: "Uh . . .
Columbia County ... Uh ... do
you have right- or left-hand traf­
fic?" At this point the hackles went
up on the back of my neck. What
was up with this inbound pilot?
Had he done
no planning
whatsoever for
evant parts of FAR 91.103 just for
a moment. lt states: "Each pilot in
command shall, before beginning
a flight, become familiar with all
available information concerning
that flight. This information must
include: (a) For a flight ... not in the
vicinity of an airport, weather re­
ports and forecasts, fuel require­
ments, alternatives available if the
planned flight cannot be com­
pleted ... (b) For any flight, run­
way lengths at airports of intended
use ...."
Let's take a look at where we
might go to obtain all that avail­
able information, and as well,
how to document that we have
indeed gotten all that informa­
tion. Let us also be aware that the
terms "all available information
and "in the vicinity of an airport"
are not defined in FAR Part 1. Thus
there is the potential to incur a vi­
olation of these regulations predi­
cated upon the interpretation of a
local FAA inspector. Whether their
interpretation stands up, would
remain to be determined by the
National Transportation Safety
Board, but in the meantime, if a
pilot is charged with a violation,
that pilot would have to spend
significant time and expense in
his or her own defense.
Certainly one of the best places
to start is either with a briefer or
by obtaining a direct user access
terminal system (DUATS) brief­
ing. Regardless of which source
we use, there is a record kept of
our having gotten that briefing. I
II
his flight?
Had he done no planning whatso­
ever for his fl ight? Was he totally
reliant upon others to give him the
information that he needed? Did
he not have a sectional chart or an
Airport/Facility Directory (A/FD) with
him in the airplane that provided
at least some of the information for
which he seemed ignorant? I'm sur­
prised he didn't ask the traffic pat­
tern altitude as his next question.
And lastly, was he unaware of FAR
91.103, Preflight Action?
Let's review some important rel­
can't help but wonder it the pilot
described above had bothered to
get a briefing. Had he come to the
airport yesterday at the same time
of day as he had in the described
scenario, he would have had a
chance to observe some military
aircraft up close and personal, as
our airport was closed for a presi­
dential temporary flight restric­
tion (TFR) until late afternoon.
Nowhere in 91.103 do we see TFRs
included in "all available informa­
tion, /I but I can assure you that
this regulation would be referred
to in the document charging a pi­
lot with a violation.
There are certainly many other
resources for obtaining weather
information in addition to flight
service and the DUATS prOViders,
and many of us, myself included,
do indeed use those resources. In
fact I typically look at several dif­
ferent Internet websites to obtain
some fantastic weather informa­
tion, AviationWeather.gov head­
ing the list. For me a picture is
worth a thousand words, and the
graphical information available
on these websites makes my self­
briefing much more valuable. But
the question remains, how do we
document that we have been to
those websites? The simplest way
I know is to print out the relative
web pages we have viewed.
It might be difficult to prove that
we have ensured sufficient fuel for
the trip, and I can assure you that
many pilots have been successfully
charged with violation of 91.103
in fuel exhaustion accidents and
incidents. Quite often these viola­
tions come about as a result of the
pilot's own admission of negligence
in one way or another. Forewarned
should be forearmed.
Okay, you say that your flight
will be in the vicinity of the airport,
and therefore you might not have
gotten a briefing. But let us all be
aware that the FAA chief counsel
said that "The FAA has no specific,
fixed definition of 'vicinity,' but
instead, interprets its meaning on
a case-by-case basis./I (1-28-92) In

some situations, anything away
from the traffic pattern might be
interpreted as not in the vicinity of
the airport. All I will say here is that
a word to the wise should suffice.
Let 's go back to that pilot in­
bound to my home base. On that
particular day, the wind had been
lightly blowing out of the south
all day long. Had our errant pilot
gotten a briefing he should have
been aware of that fact, even if
he was oblivious to the tail wind
pushing him northward. With the
runway at my home base aligned
03-21, it should have been self-ev­
ident that landings that day would
be to the south.
But even if he hadn't been aware
of the southerly winds, a check of
the AWOS prior to reaching "10
miles out" would have informed
him of the winds. Certainly if he
had a current sectional on board,
that frequency would have been
available to him. And the ques­
tion about right- or left-hand traf­
fic would have been answered on
that sectional as well. If there were
right-hand traffic for either or all
runways, it would be denoted in
the airport data information on
the sectional chart with the nota­
tion "RP" and for which runway(s).
Another source for this infor­
mation is the Airport/Facility Direc­
tory, also known as the little green
book. Perhaps you live in an area
where it is difficult to get a cur­
rent copy of the A/FD. And it will
be getting even harder as the gov­
ernment cuts back on the number
of fixed base operators and flight
schools that can sell these, as the
government increases the volume
requirements to qualify as a dealer.
If that is your situation, please be
aware that the A/FD is now avail­
able in a digital format on the FAA
website. Go to www.NACO.FAA.
gov/index.asp?xml=nac%nline/d_
afd where you can download the
information for the airports of
your intended landings.
There are some pilots who would
consider the term "all available in­
formation" as somewhat ambigu­
ous and therefore disregard the
need to get as much info as they
can prior to a flight. Failing to do
so might get a pilot in trouble with
the FAA, but more importantly,
not having as much information
as one can possibly have could put
one in an unsafe situation. A pilot
who just "kicks the tires and lights
the fires" without finding out as
much as possible about everything
relative to the flight is being negli­
gent in the duties of being a pilot
in command.
So the next time you are beck­
oned aloft by blue skies and tail
winds, be sure that you launch
with as much" available informa­
tion" as you can get.

Aviation (Lane, D.R . The Thaden
Argonaut: All Metal, Six Passen­
ger, High Wing Cabin Monoplane
Is Powered With a Pratt & Whitney
Wasp Engine. February 13, 1928,
pp 386-388), the T-1 was the
brainchild of ex-U.S. Army Signal
Corps pilot (1), and aeronautical
engineer, Herbert von Thaden.
While Thaden's wife, Louise,
is much better-known in avia­
tion circles due to her extensive
record-setting flying skills and
contributions to numerous avia­
tion organizations, Herbert von
Thaden designed at least three
aircraft between 1928 and 1930.
Constructed at San Francisco
by the Thaden Metal Aircraft Co.,
the T-1 (NX3902) was test-flown at
Crissy Field. The steel framework
was covered with corrugated du­
ralumin, which is alleged to have
given the airplane better-than­
expected performance. Patented
removable panels (Thaden held
four U.S. aeronautical patents)
on the underside of the wings al­
lowed relatively easy, and thor­
ough, inspection of the underly­
ing structure and fuel tanks. The
box wing spars were covered with
the same corrugated duralumin
as the skin and were permanently
riveted to the upper surface. The
fuselage utilized Thaden's unique
monocoque construction that
employed transverse members
combined with stressed corru­
gated skin in place of longerons .
Bulkheads in the cabin and tubu­
lar duralumin frames were used
aft of the cabin, but no longitu­
dinal members were used aft of
the engine mount. The fuel tanks
(120 gallons, enough for a six­
hour duration) were mounted in
the wings above the access pan­
els, and the fuel was fed directly
into the carburetor, with no fuel
line entering the cabin. A fire­
proof bulkhead separated the en­
gine from the cabin for extra pro­
tection against fire.
The undercarriage was of a split
oleo-pneumatic type with hinged
tripod strut-work. Each half of
the main gear also incorporated
a Gruss shock absorber, and the
stout-looking tailskid incorpo­
rated a pneumatic shock absorber.
Sauzedde wheels and brakes were
fitted to the main gear.
The strut-braced wings had a
span of 53 feet 8 inches, the fuse­
lage a length of 35 feet 3 inches,
and the height was 11 feet, which
gave the Argonaut an imposing
physical appearance. The cabin
normally seated six passengers,
but could be arranged to accom­
mod ate up to eight persons. The
control surfaces and stabilizers
were of the same construction as
the rest of the airframe. The con­
trols were operated by pushrods,
and a control yoke suspended
from the engine mount was used
for longitudinal and lateral con­
trol. Conventional rudder ped­
als operated the rudder. A wheel,
located to the right of the pilot's
seat, was used to operate the el­
evator trim, and the horizontal
stabilizer was ground-adjustable.

was insulated and soundproofed
for passenger comfort, and a heat­
ing and ventilation system was in­
corporated. The seats were made
of wicker, and ample legroom was
provided. An oval entrance door,
located on the left side of the
cabin, allowed ingress into and
egress from the cabin. A unique
aspect of the door was that the
corrugations did not run perpen­
dicular to the frame, being angled
instead. A baggage compartment
was located just aft of the cabin,
and windows made of shatter­
proof glass gave the passengers a
good view of the outside.
Empty weight of the aircraft
was 2,900 pounds, and a use­
ful load of 2,200 pounds could
be carried. The 415-hp Pratt &
Whitney Wasp was originally de­
signed as the competitor to the
Wright Simoon. The first engine
was ready by Christmas of 1925,
and after testing in the Wright
F3W-l Apache, it was placed
into production in late 1926. By
early 1927, 12 were being deliv­
ered per month. The engine actu­
ally displaced 1,344 cubic inches
(rounded off to 1,340 cubic inches
for statistical purposes) and had
a bore and stroke of 5.75 inches.
The T-1 used a Wasp A, of 400-420
hp, and a ground-adjustable Stan­
dard propeller. First flown on 15
January 1929, the T-l was found
to have a maximum speed of 135
mph, a cruise of 105 mph, and a
minimum speed of 52 mph.
Thaden drew his engineering
force from Handley-Page in Eng­
land, from Ford in Detroit, and
from top American technical
schools. E.T. Todd, associate engi­
neer at the Thaden Metal Aircraft
Corp., was, like his peers, required
to have actual aviation experience
as a pilot, a unique aspect of the
company. Organized at San Fran­
cisco, R.E. Fisher was company
preSident, with Donald McKee,
as secretary; W.D. Dickey, as trea­
surer; W.A. Bechtel, as chairman
of the executive committee; and
E.H. Heller and C.A.A. McGee, as
counsel. Thaden served as vice
president and manager.
Following the 1928 T-l, the T-2
(7074, cln 2) was also constructed
in 1928. Described in Flight (The
Thaden T-2: An American All Metal
Commercial Monoplane. January
10, 1929, P 26), it was broadly
similar to the Argonaut, but was
smaller. Powered by a 150-hp
Comet, it had a span of 39 feet
and an overall length of 26 feet.
Unlike the T-l , the four-place T-2
had a fully cantilevered wing with
trailing edge flaps. The T-2 had
a VMAX of 121 mph, aVe of 90
mph, and a VM1N of 46 mph. The
useful load was 1,180 pounds.
The T-3 was apparently never
built but may have been modified
to become Thaden's last airplane,
the T-4. Constructed in 1930 as
a Group 2 certificated aircraft (2­
247), the T-4 was powered by a

We need to get behind HR 3678 and contact our represen­
tatives to let them know this bill is supported by general
aviation. Locating and communicating with your repre­
sentatives can easily be accomplished at www.House.gov/
houseiMemberWWW_by_State.shtm/.
Your EAA Industry and Regulatory Affairs department
has done a good job of getting this information out to
our membership, but the further we spread this type of
news, the better. Please take the time to communicate
with your congressional representatives about this im­
portant issue.
Remember, it's time to set your aircraft up for winter
operations. It's time to get that manual out and review
the section on cold-weather operations. Winter flying
can be a lot of fun, but you have to be prepared for it. Be
safe out there.
As always, please do us all the favor of inviting a
friend to join the VAA, and help keep us the strong asso­
ciation we have all enjoyed for so many years.

and you 're busy flying and showing it off? If so, we 'd like to
hear from you. Send us a 4-by-6-inch print from a commercial
source (no home printers, please-those prints just don't
scan well) or a 4-by-6-inch , 300-dpi digital photo. A JPG from
your 2.5-megapixel (or higher) digital camera is fine. You can
