Airworthiness Directives; Fokker Model F27 Mark 050 Series Airplanes

요약

This amendment adopts a new airworthiness directive (AD), applicable to certain Fokker Model F27 Mark 050 series airplanes. This action requires the removal of tapered nylon shims from under the seat rails from fuselage station 14025 to the aft end of the seat rails, and installation of shorter bolts. This action also requires the installation of shims under galleys and partition walls for certain configurations. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent failure of the seat rail attachments due to shim material aging, which could result in detachment of the seats and consequent injury to the airplane occupants.
