Airworthiness Directives; Fokker Model F.28 Mark 1000, 2000, 3000, and 4000 Series Airplanes

요약

This amendment adopts a new airworthiness directive (AD), applicable to all Fokker Model F.28 Mark 1000, 2000, 3000, and 4000 series airplanes, that requires repetitive inspections of the center joint of the main landing gear (MLG) torque link and the MLG assembly for excessive free-play; and correction, if necessary. This AD also requires installation of new MLG torque link dampers, which constitutes terminating action for the repetitive inspections; and revision of the FAA-approved maintenance program to incorporate inspections and overhaul of the new torque link dampers. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent the failure of MLG torque links, which could result in reduced controllability of the airplane on the ground during takeoff or landing.
