Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Fokker Model F.28 Mark 0070 and 0100 airplanes. This AD requires inspecting the main landing gear (MLG) main fitting for cracks, and repair if necessary. This AD also requires installing a placard and revising the airplane flight manual to include procedures to prohibit the application of brakes during backward movement of the airplane. This AD results from a report that an MLG main fitting failed on an airplane that was braking while moving backward. We are issuing this AD to detect and correct cracks in the MLG main fitting, which could result in reduced structural integrity of the MLG main fitting.
