Cunningham, ASS #3228, 9000 Sovereign Row, Dallas, TX 75247, represents the degree of sophistication found in some Bonanzas being flown today. Mr. Cunningham uses his plane for all his traveling connected with business throughout the Texas and Oklahoma areas. He writes: "We submit this 'bird' for your Bonanza of the Month! The electronics are a complete King Gold Crown package together with Bonzer radar altimeter and Mitchell Century III autopilot with glideslope coupler.

Bth, attended by a substantial number of ABS pilots, it was agreed that there was considerable interest in the formation of a Southeast Chapter of the ASS. Paul R. Morton, temporary chairman o f the organizational c~tee, reports the first fly-in and aeeting viII be held at Jekyll Island. Georgia . Nov . 17-19 , 1972. Here's the details--everyone interested s hould t r y to attend. Dear Ralph : Several ABS members met in the Seminar 2 room at the Diplomat Ho tel on Oct. B. 197 2, during the AOPA Plantation Party with the express purpose of discussing formation o f a Southeaat Chapter of the ABS. It waa unanimously agreed t o aove in this direction . The group aaked me to act as t emporary chairman to make arrangements for the organizational meeting. I have bee~ ably a.sisted by Don Nickell. Bob Diamond, John St..Dns, Pred Meyers and Joe Cosentino. There will be an organizationsl meeting and fly-in on the weekend of Hov. 17th, 18th, and 19th, at Jeky ll I sland, Georgia. to fora the Southeast Chapter o f the ABS. ~ member interested In attending this meeting to help get i t off to a good atart ia cordially welcoae . Bring the wife and kids too. The business meeting will be at 2 p.m. at the Wanderer Motel, Nov. 18th . All ABS members who wish to at tend may make res ervations by writlaa or phoning Mrs. MBdeline Simpson, Wanderer Motel, Jekyll Island, Georlia 31520, phone (912) 635- 2211. We have arranged for double room flat rate of $16 for ABS aeabera attending. Mrs . Siapaon said she would give ua her niceat rooms on a first come. firat served basis. The sirport has a paved north/south runway 3000' lQng. 80/87 and 100/130 octane fuel, Unicom on l22.B, Avis and Hertz rental cars; motel furnishes transportation t o it's facility. Swimming 8uits and golf clubs may be useful-weather permitting. The aim of this group is for good fellowship. avia tion conversation and trading of ideas relating to "six-cylinder" Bonanzas. Also, we are hoping to provide for a couple of interesting week-end fly-ins each year to achieve this goal. Paul R. Horton. ABS '749 2704 Northwest 51 Place Ft. Lauderdale.

Thes. coils are placed with .... at 90- to each other and 45- either slde of vertical . The field atrengths produced by the co i la are deter.toed by the current flow through th~1 which 18 in turn d.te~laed by the voltage difference acro •• thea. The voltale d~fferences sre in tUrD deterained by the voltage level of the fra.e of the laule, which 1. connected between the colis, which voltage level is deterained by the resistaDce of the tank tran.. itter potentio.eter, which is deterained by the poSition of the tank float. For example, when the tank is ~pty, the resiatance of the transmitter is low. This ca~es the voltaae level of the gauge fraae to be near zero, wbdch ca~es a large current flow throuah the coil connected betveea A+ (l4v . ) and the gaule fraae (I will can it the ".-pty poSition coil"). and a ...11 current flow throuch the coil connected between the gauge freae and around (I will call this the "full position coil"). When the taak 1s full, tbe reaistance of the tank trana.ttter 1s hilh, and the voltaae level of the gauge fr ... ia Dear 14 volts. This causes a larae current flow in the full poeition coil and a ...11 current flow in the eapty position coil. A chanae 1a A+ volta,e affects both coils approximately proportionately, . .king the gaule insenaitive to such voltale chanaes. Each coil is attached to the gauge fraae by a small bolt which passes through a slot in the frame bracket . This bolt i8 ordiDarily aafetied with red paint. which I interpret to ..an "do not break aeal unless you know what you are doiac." Once the paint seal ia broken and the bolt loosened. the coil can be slid the length of the slot so as to vary its distance fro. the armature. lefore calibrating the gauge. one should, of course. deteraine that all parts of the syatea are working properly. In particular, check to aee that the trana.itter ara works freely aad that the float can move all the way from top to botta. of tank.

You can imagine my chagrin wben the plane came to a screeching baIt with the noae aD the ground. Anyway. the plane was returned to service in cwo .outh_, the holdup being due to Beech not being able to supply the noae akins despite the fact that in the last Hevsletter the Beech people claim to bave such good delivery on their parts. On March 20. I got the plane back, aDd on the 21st. I v •• flying it into Denver, with my wife a • • pa•• enger. with approxfmately 1 1/2 hours' flying time aince the accident. Everything seemed to be beautiful until there vaa a loud bang and a staccato-like aound. stmilar to vhen a machine gun livea a ahort burat, and then total lack of engine reaponae to any of the controla. Ve vere about eleven a11ea aouth of Akron, Colorado, and I hoped to get partial paver from the engine and limp back to the Akron Airport. I had read where people ~ith aia1lar probleaa had some power left even though they bad a aevere failure, but aa I eay. I bad no power so the engine v.a ahut off and a prayer v.a eaid for the engine to atop Vibrating, which did slow down a8 the enaine began to vindaill dover . Ve planned. to land in a pa.ture that appeared below ua, but aa I got cloaer to the ground, I realized there vaa a gravel road riaht next to the paature so it va. elected to .verve onto tbe road. After the fencea were cleared. and ve vere over the road, I put the gear down. At thia time ve vere still at 120. I held the plane off long enough for the gear to come down and there vas no daaage to the airframe. The engine va. taken out and a new one installed by eo.b. Aircraft in Denver, and I flev the plane out one veek later. NOv as to the cause of the failure, Continental'. repreaectative, Mel Br1dg.... ter. came and looked the engine over.• alona vith the people .t Combs Aircraft in Denver. It vaa found that the hanger on the crank.haft that supports one of the counterweights had cracked, even though the engine had been shut down to a total idle when the prop struck the ground suddenly. As a reault. aoon after ve began to uae the enaine, thia banaer faUed and the counterweight broke into pieces, broke the connect ina rod of the #2 cylinder and ezploded the caae riaht underneath the aa81letos. Thia explain. vby there va. 00 power after the incident becau.e the aaaneto. vere both totally loo.e from their .aunting.. Continental MOtor. bas a bulletin out concernina .udden .toppage of this engine. It 8aya that the only aafe way i. to totally diaaantle the engine and eza.1ne theae hanaera on the crankabaft because of the po.aibility of thia occurrence. Uaually, the Inaurance Co.panies do DOt VADt to 'Pay for tearina: down an engine-but still, it's your life-and i ' this ahould happen to you, I would nronaly advise baving the enaine torn down--hav1.na a total faUure and. a forced. land1na is Very nerve-racking.

SRAlC-7 AP unit ina taIled in lUlsaSe I eoapar~ent of Bonanza October 29, 1972 Page 275 COMMENTS AND CORRESPONDENCE ANOTHER INTERESTING INSTALLATION OF AN ELT Dear Ralph: Possibly the following information can save other Bonanza owners the time that I spent searching out the most desirable ELT for my 35833. By the way. I am not promoting Larago Electronics but do believe they do have a good product and the best for the application. My purpose was to find a high output unit with a Gswitch that would operate automatically in any directio n except vertically. The unit had to have a positive connec tion battery pack and be installed with a top fuselage external antenna. The Larago model l005-AP satisfied the above requirements and in addition, I received the following benefits: 1. The unit as installed is completely automatic on impact; however, I can reach down and change the selector from automatic to the ON position for any emergency while still at altitude (most effective range). 2. The unit is mounted on the fiberglas over the fuel valve (we reinforced the fiberglas with a thin sheet of aluminum) and immediately aft of the fuel selector valve (the light for the fuel selector valve was moved to the right approximately 3 in.). The height of this unit is such that, when moun t ed in this position, the pilot's seat can be moved full forward with no interference. 3. The antenna lead supplied is long enough such that the antenna is mounted in top center of the fuselage (behind the air scoop) with the lead brought down inside the side post (between the two large side windows) and thru the side upholstery (beside the antenna post on the ELT). 4. On a downed aircraft the ELT is automatic, and if the pilot can crawl out, it takes 3 seconds to disconnect the fixed antenna and release the mounting bracket. He then has a portable unit with self contained batteries and telescoping antenna to carry with him. We have already installed this unit in a "K," an "s" and another "833." Donald H.

BARON BRAKES INSTALLED ON F-35. P- 35 BONANZAS If you've been unhappy about the operation and maintenance of your present Braking system, Herbert A. Hiller, ABS 82494, suggests changing to the Baron-type Cleveland brakes. This was mentioned briefly in an earlier Newsletter (page 141, Dec. 1970). Dear Ralph: I just arrived from Puerto Rico and I am also too late to make the Milwaukee Convention to which I hoped to bring the information with me on the Baron brakes that I have on the F-35 and P-35 Bonanzas which I own . I have enclosed a copy of the parts list and a Form 337 , which can help. Not all aircraft models will have to have the spacers; the P-35 did not require any.

Off and on I had been sme l ling raw fuel occasionally in the cockpit during and after a flight. Inspection did not reveal any source of leaking fuel. Following an annual inspection, the plane was flown to Newark, Ohio, during a rain, and again, the odor of fuel was strong. The following evening the plane was returned to Ohio State University where it is based. Again . the odor of fuel quite strong which I attributed to t he moderate chop in the rain (Agnes' backside). Examinat ion showed some green dye stains on the bottom of the left cowling . This was called to the attention of the A & P who did the annual. He looked the plane over and could find no reason for the stains or for the odor which, of course, had dissipated. The plane was not flown until the 4th of July which was almost 2 weeks later . Again, a very strong odor of raw gasoline in the cabin so I headed for Port Columbus as I did not want to contribute to the aerial fireworks display over the usual parade in in Upper Arlington. Luckily I found Pete Esselburne who did the annual at Columbus Flying Ser vice. Upon getting out of the plane I could see fuel dripping from the bottom of the cowling. By operating the wobble pump we discovered a leak in the vapor return line to t he left main. This line (which returns excess fuel at the rate of 3 gallons per hour in the 0- 470G-- even higher in o t her engines like the IO- 47OC and 10-520) was, and had been , apparently chafing against the main fuel line to the carburetor . Replacement of this vapor return line corrected the problem and there is a noticeable improvement in fuel consumption. Perhaps everyone should have an inspection made of this line to ensure freedom from chafing . William B. Gest. ABS #539 3900 Bramford Road Columbus, OH 43221 Dear Sirs : I thought that the following incident might be of some help to my fe l low Bonanza owners. As yo u know the K-35 with aux. tanks has a four pOSit ion fuel tank selector which reads counter clockwise--off, left main , aux . , right main. After having the Beech 'fuel tank conversion to eliminat e fuel starvation during fast t axi t urns and prolonged slips, the new tank selector decal showing the selector positions reads--off, left main, right main. This decal leaves out the true left main position and shows the left main in the aux. position with no aux. pOS it ion shown. I discovered this after having an engine failure due to fuel starvation on take-off, on the following day after the conversion, with the fuel selector showing left main which in fact was the aux. position. Thankfully, no damage was done due to having a long runway. Upon exami ning the decal kit having been supplied by Beech, Hawthorne Aviation, Charleston, SC , found that there was no correct decal for the K- 35 with built - in wing aux. tanks . They have notified Beech of this and FAA, Columbia, SC, also. I hope that this report will help before someone has this problem on a short field . E. C. Stalvey, Jr., ABS U4393 P. O. Drawer V Georgetown , SC 29440 SINGLE-ENGINE IFR IS LEGAL IN MEXICO ~ Last month the question of flying a Single-engine plane IFR in Mexico was raised. Checking with our local FSS, they reported back information received from the El Paso FSS to the effect that single-engine IFR was lega l prOViding you had a copilot and dual instrumentation. This is not accurate and we apologize for the misinformation. A number of our members brought this to our attention including Howard Q. Chilton, Jr., ABS #4561, whose letter below clari~ the situation. The International Flight Information Manual, found in U. S. Flight Service Stations , reports the personal and air craft entry requirements of foreign countries. The report of Mexican requirements states that night flights ~ be IFR . Radio Aeronautica Mexicana, S. A. ' s (RAMSA) charges for air navigation services are also listed in this publication as well as aerodromes of entry. Dear Mr. Haesloop, As a new ABS member I would like to compliment you on your fine organization and monthly publication . Through the current and back issues, I have found a wealth of information about my P- 35 Bonanza. Unfortunately my first letter to you is to take exception with the comments of Mr . C. E. Bartels of HOUSton, Texas, regarding single-engine IFR in Mexico. After seven years of residence in Mexico and hearing or reading of numerous misconceptions on this matter, I would like to set the record straight. There are no restrictions to single - engine IFR flights in Mexico at all, provided the aircraft is properly equipped for the naVigational facilities to be used, and the pilot is properly rated. Perhaps Mr. Bartels' misunderstanding of the regulations in Mexico stems from either or both of the following rules: 1. There is no night VFR in Mexico and/or 2 . The local "commandante" must sign the flight plan, and before doing so, must be convinced the flight may be safely undertaken. If you have met the requirements (generally the same as FAA), there is no reason why your ,flight plan should be refused. The "command ante " still has the final authority, but you can spend an additional day enjoying the lovely advantages of oar country. content with the knowledge you are right and he is wrong. I hope to Soon have a copy of the regulations and the translation so ABS members may carry it with them on their trips to Mexico in caSe of misunderstanding. I hold a FAA commercial SMEL instrument and Mexican private SMEL instrument with time f r om Luscombes to F-I04's. Even so, I don ' t fly single-engine night, or IFR with minimums of less than 1000 feet enroute, because of the mountains. We like to have visitors to our wonderful Mexico, but because of the language problems we often sympathize with the poor "turista" who doesn't have all of the conveniences he is used to. Mexico is constantly improving its navigational and airport facilities, and many of our flight service personnel are now completely bilingual. If I can be of any help to pilots coming to Mexico, please feel free to calIon me. Howard G. Chilton , Jr., ABS #4561 Dos de Abril 821 Mexico 19, OF
