Airworthiness Directive · Amendment 39-14418 · Boeing Model 767-200, -300, and -300F Series Airplanes
Boeing Model 767-200, -300, and -300F Series Airplanes
This AD applies to Boeing Model 767-200, -300, and -300F series airplanes, certificated in any category, L/Ns 837 through 918 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, and -300F series airplanes. This AD requires replacing the aileron control override quadrant with a modified unit. This AD results from 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.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 18 months after the effective date of this AD, replace the aileron control override quadrant with a modified unit, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 767-27A0175, Revision 1, dated June 3, 2004; or Boeing Service Bulletin 767-27A0175, Revision 2, dated August 5, 2004.
Note 1: This AD does not require accomplishing the actions specified by Step 5 of Figure 2 of Boeing Alert Service Bulletin 767-27A0175, Revision 1, or Boeing Service Bulletin 767-27A0175, Revision 2.
As of the effective date of this AD, no person may install, on any airplane, an aileron control quadrant override assembly that has not been modified in accordance with the requirements of this AD.
