Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 767 airplanes. This proposed AD would require repetitive detailed inspections of the wire bundles, power display unit (PDU) wiring, and wire attaching hardware, supports, and sleeving located in the forward and aft lower lobe cargo compartments and corrective actions as necessary. This proposed AD results from a fire in the forward lower lobe cargo compartment found shortly after airplane arrival. We are proposing this AD to detect and correct damage to wires in the forward and aft lower lobe cargo compartments, which could result in a potential short circuit and consequent fire in the forward and aft lower lobe cargo compartments.
