Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 767-200 and - 300 series airplanes. This proposal would require 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 proposal 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 a wire installed in this area. The actions specified by the proposed 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 that allow the flight crew to stop the flow of fuel in the event of an engine fire.
