This AD was prompted by a report of the seizing of the input override mechanism bearings of the lateral central control actuator on affected airplanes. We are issuing this AD 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.
