Airworthiness Directives; Boeing Model 767 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that requires installation of sleeving on the 90-minute auxiliary power unit (APU) standby power feeder cable at body station 1351. This amendment is prompted by a report of damage to the 90-minute APU standby power feeder cable caused by shifting of unrestrained cargo containers during flight. The actions specified by this AD are intended to prevent damage to the 90-minute APU standby power feeder cable, which could result in arcing between the standby power feeder cable and the shroud of the APU fuel line, penetration of the fuel line shroud, and a consequent fire in the main deck floor above the aft cargo compartment.
