Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Fokker Model F.28 Mark 0070 and 0100 airplanes. This proposed AD would require an inspection of the main landing gear (MLG) main fitting for cracks, and repair if necessary. This proposed AD would also require 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 proposed AD results from a report that an MLG main fitting failed on an airplane that was braking while moving backward. We are proposing this AD to detect and correct cracks in the MLG main fitting, which could result in reduced structural integrity of the MLG main fitting.
