Airworthiness Directives; Boeing Model 767-200, -300, and -300F Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767-200, -300, and -300F series airplanes, that requires a one-time inspection for discrepancies of all wire bundles, including certain power feeder cables, of the electrical system in the forward cargo compartment ceiling at certain stations; and corrective actions if necessary. This action is necessary to prevent damage to wire bundles, particularly those of the fuel quantity indication system (FQIS), which are located in the subject area. Damage of FQIS wires could cause arcing between those wires and power wires in the damaged wire bundle, and may lead to transmission of electrical energy into the fuel tank, which would result in a potential source of ignition in the fuel tank. This action is intended to address the identified unsafe condition.
