EASA
AIRWORTHINESS DIRECTIVE
AD No.: 2009-0072
Date: 31 March 2009
Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with
Regulation (EC) No 216/2008 on behalf of the European Community, its Member States and
of the European third countries that participate in the activities of EASA under Article 66 of
that Regulation.
This AD is issued in accordance with EC 1702/2003, Part 21A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the
continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may operate
an aircraft to which an Airworthiness Directive applies, except in accordance with the requirements of that Airworthiness Directive
unless otherwise specified by the Agency [EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry
[EC 216/2008, Article 14(4) exemption].
Type Approval Holder’s Name :

TCDS Number :
EASA A.061
Foreign AD :

ATA 53
Fuselage - Maintenance Programme and Fuselage Front Posts Inspection / Repair
Manufacturer(s):
EADS PZL “Warszawa-Okęcie” S.A.
Applicability:
Model PZL-104 Wilga 35, 35A and 80 aeroplanes, all serial numbers.
Reason:
An inspection of a PZL-104 aeroplane that had a relatively long operational
background revealed a severe corrosion of the steel front fuselage structural
elements.
It is likely that such corrosion can also be present on other aeroplanes of similar
design and operational history.
If left uncorrected, this condition could lead to loss of strength of the structural
front posts elements and consequent reduction of the structural strength of the
aeroplane.
For the reason stated above, this Airworthiness Directive (AD) mandates
inspecting the fuselage front posts, repairing any corrosion found and replacing
pads made of foam rubber by pads made of Neoprene to prevent water
ingression.
Effective Date:
EASA Form 110
14 April 2009
