Airworthiness Directives; Boeing Model 767-200, -300, and -300F Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that requires replacement of the aileron control override quadrant with a modified unit. The actions specified by this 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.
