## Summary

This document revises an earlier proposed airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that would have required replacement of the aileron control override quadrant with a modified unit. This new action revises the applicability of the proposed rule. The actions specified by this new proposed AD are intended to prevent corrosion of the input override mechanism bearings of the lateral central control actuator, which, in the event of a subsequent jam in the pilot's aileron control system, could result in failure of the aileron override system and consequent reduced lateral controllability of the airplane. This action is intended to address the identified unsafe condition.
