Aircraft Parts and Development Corporation, FS2000/FS2001/FS2002/FS2003 Corp., Lavia Argentina S.A. (Laviasa), Piper, Maule and Taylorcraft aircraft with sealed wing lift struts (see below for more detail) Reason for Airworthiness Concern:
Unsealing of Sealed Wing Lift Struts, especially by venting during powder coating process FAA Description of Airworthiness Concern The FAA has issued the Airworthiness Directives (ADs) in Table 1 requiring actions on the wing lift struts to reduce the potential for fatigue or corrosion leading to in-flight separation of the wing. Each AD requires installation of sealed struts or permanent sealing of vented struts as terminating action for their respective inspection requirements.
Table 1 AD Type Certificate Holder 73-22-02 Aircraft Parts and Development Corporation 98-15-18 Maule Aerospace Technology Corp.
99-01-05 The New Piper Aircraft, Inc.
FS2000/FS2001/FS2002/FS2003 Corp Lavia Argentina S.A. (Laviasa) 99-26-12 The New Piper Aircraft, Inc. (Piper) 2008-04-09 Taylorcraft, Inc.
Taylorcraft 2000, LLC Powder coating processes are used on certain aircraft parts to provide a protective coating. Sealed struts must be vented as part of the powder coat application, effectively violating the intent of the listed ADs to require either repetitive inspections or permanently sealed strut assemblies. The FAA has issued Safety Alert for Operators (SAFO) 10018 discussing the topic.
If undetected, venting of sealed lift struts could eventually lead to corrosion and / or cracking of the lift struts, and result in a potential safety of flight hazard such as wing separation.
The following is a reference-only list of affected aircraft models. See the ADs in Table 1 for further details on applicability.

Request for Information (Proposed Alternate Inspection/Repair Procedures, Cost Impact, etc.):
The FAA is soliciting additional information from Associations and Type Clubs in accordance with the Small Airplane Directorate AD Manual Supplement. We are particularly interested in all powder coating processes or other actions that might be used on lift struts and cause them to be unsealed. We are also especially interested in documentation where the process has actually been used. This and any additional information such as service problems, proposed alternate inspection/repair procedures, cost impact, etc. should be returned in writing to the FAA (address listed above). All comments or replies need to be as detailed as possible and include specific examples to illustrate the comments/concerns.
This Airworthiness Concern Sheet (ACS) is intended as a means for FAA Aviation Safety Engineers to coordinate airworthiness concerns with aircraft owner/operators through associations and type clubs. At this time, the FAA has not made a determination on what type of corrective action (if any) should be taken. The resolution of this airworthiness concern could involve an AD action or an SAIB, or the FAA could determine that no action is needed at this time. The initial Risk Assessment for this concern does not indicate that an Airworthiness Directive would be considered, however, the existing AD could require revision or supersedure to ensure safety and proper compliance. The FAA's final determination will depend in part on the information received in response to this Airworthiness Concern Sheet.
The FAA endorses dissemination of this technical information to all manufacturers and requests association and type club comments.
