Summary
This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain Fokker Model F.28 Mark 0070 series airplanes, that currently requires a one-time inspection to detect loose bolts attaching the gustlock counter-bracket to the pulley on the elevator tension regulator (control) assembly, and corrective action if necessary. This action would instead require a modification of the elevator tension control mechanism. This action would also revise the applicability to include additional airplanes. The actions specified by the proposed AD are intended to prevent restricted elevator movement and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
