Airworthiness Directives: Piper Aircraft Corporation; PA28R, PA28RT, and PA44 Series Airplanes

Краткое содержание

This amendment adopts a new airworthiness directive (AD) that applies to certain Piper Aircraft Corporation (Piper) PA28R, PA28RT, and PA44 series airplanes. This action requires installing a certain nose landing gear modification kit. Several service difficulty reports of collapsed nosegear on the affected airplanes prompted this action. In particular, these reports reveal failure of the bolt (AN4-20) connecting the lower drag link of the nosegear to the upper drag link. The actions specified by this AD are intended to prevent nose gear collapse because of AN4-20 bolt failure, which could lead to airplane damage.
