Airworthiness Directive · Amendment 39-10433 · Boeing Model 767-200 and -300 Series Airplanes
Boeing Model 767-200 and -300 Series Airplanes
Model 767-200 and -300 series airplanes; as listed in Boeing Service Bulletin 767-33-0052, Revision 1, dated December 8, 1994, as revised by Notice of Status Change 767-33-0052 NSC 01, dated May 9, 1996; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767-200 and -300 series airplanes, that requires a one-time inspection for worn or broken wire bundles in the ceiling above the main passenger door and repair, if necessary; and relocation of the wire bundles to prevent chafing. This amendment is prompted by a report indicating that the opening of the main passenger door caused the door liner and a ceiling panel to chafe and ultimately break wires installed in this area. The actions specified by this AD are intended to prevent these wires from becoming worn or breaking, which could lead to the failure of several systems, such as the fuel shutoff valves, and may contribute to the inability of the flight crew to stop the flow of fuel to the engines in the event of an engine fire.
