## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 airplanes. This proposed AD would require inspecting the carbon-fiber reinforced plastic (CFRP) main landing gear (MLG) door to determine whether certain part numbers are installed. For airplanes having certain doors, this proposed AD would require inspecting the MLG outboard door for cracks, play, and loose sealant/bolts/nuts, and related investigative and corrective actions if necessary. This proposed AD would also require, for airplanes having certain doors, modifying the rod bracket attachment of the MLG outboard door. This proposed AD results from a report of a rod bracket of the MLG door detaching during flight. We are proposing this AD to detect and correct cracks in the rod bracket attachment bolts, which could result in the rod brackets detaching from the MLG door and blocking the proper functioning of the MLG.
