Airworthiness Directive · Amendment 39-9654 · Piper Aircraft, Inc. Airplanes
Piper Aircraft, Inc. Airplanes
Superseded. A later AD replaced this one: AD 2016-05-01. Comply with the one in force.
This AD applies to Piper Aircraft, Inc. PA-31, PA-31-300, PA-31-325, PA-31-350.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment supersedes Airworthiness Directive (AD) 80-22-04, which currently requires the following on The New Piper Aircraft, Inc. (Piper) Models PA31, PA31-300, PA31-325, and PA31-350 airplanes: repetitively inspecting the upper section of Fuselage Station (FS) 317.75 bulkhead for cracks, and incorporating a certain reinforcement kit if any crack is found. This action requires inspecting (one-time) the upper section of the FS 317.75 bulkhead for cracks, and incorporating one of two reinforcement kits depending on whether cracks are found in the FS 317.75 bulkhead area. Cracks found on airplanes in compliance with the inspection requirements of AD 80-22-04 and the Federal Aviation Administration's policy on aging commuter-class aircraft prompted this action. The actions specified in this AD are intended to prevent structural failure of the vertical fin forward spar caused by cracks in the FS 317.75 bulkhead, which, if not detected and corrected, could result in lossof control of the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
