Airworthiness Directives: Piper Aircraft Corporation PA24, PA30, and PA39 Series Airplanes

Краткое содержание

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.
