Airworthiness Directive · Amendment 39-8951 · Piper Aircraft Inc. Airplanes
Piper Aircraft Inc. Airplanes
This AD applies to Piper Aircraft Inc. PA-24, PA-24-250, PA-24-260, PA-24-400, PA-30, PA-39.
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) 74-13-01, which currently requires inspecting (one-time) the stabilator torque tube bearing support fittings for looseness on certain Piper Aircraft Corporation (Piper) PA24, PA30, and PA39 series airplanes, and, if looseness is found, incorporating Piper Part No. 760 835 (Hi-Shear Rivet Replacement Kit). This action retains the initial inspection of the stabilator torque tube bearing support fittings, and makes these inspections repetitive unless the above referenced service kit is incorporated. Incidents of looseness of the stabilator torque tube bearing support fittings on several of the affected airplanes in compliance with the current AD prompted this action. The actions specified by this AD are intended to prevent loss of pitch control because of looseness of the stabilator torque tube bearing support fittings, which could result in loss of 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.
