Airworthiness Directives: Piper Aircraft Corporation Models PA34- 200, PA34-200T, PA34-220T, PA44-180, and PA44-180T Airplanes

Краткое содержание

This amendment adopts a new airworthiness directive (AD) that applies to certain Piper Aircraft Corporation (Piper) Models PA34-200, PA34-200T, PA34-220T, PA44-180, and PA44-180T airplanes. This action requires repetitively inspecting the main landing gear trunnions for cracks, replacing any trunnions found cracked, and eventually replacing these trunnions with improved parts as terminating action for the repetitive inspection requirement. Several reports of the main landing gear trunnions cracking on the affected airplanes prompted this action. The actions specified by this AD are intended to prevent collapse of the main landing gear caused by cracked trunnions, which could result in airplane damage.
