Airworthiness Directive · Amendment 39-15157 · Boeing Model 767 Airplanes
Boeing Model 767 Airplanes
This AD applies to all Model 767-200, -300, -300F, and -400ER series airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 767 airplanes. This AD requires repetitive detailed inspections of the wire bundles, power drive 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 AD results from a fire in the forward lower lobe cargo compartment found shortly after airplane arrival. We are issuing 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.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 36 months after the effective date of this AD, do detailed inspections for damage to the wire bundles, power drive unit wiring, and wire attaching hardware, supports, and sleeving located in the forward and aft lower lobe cargo compartments; and do all applicable corrective actions before further flight after the inspections; by accomplishing all of the actions specified in the Accomplishment Instructions of Boeing Service Bulletin 767-25-0376, Revision 1, dated February 9, 2007 (for Model 767-200, -300, and -300F series airplanes); or Boeing Service Bulletin 767-25-0377, Revision 1, dated February 9, 2007 (for Model 767-400ER series airplanes); as applicable. Repeat the inspections thereafter at intervals not to exceed 24,000 flight hours or 72 months, whichever occurs first.
Actions accomplished before the effective date of this AD in accordance with Boeing Service Bulletin 767-25-0376, dated November 17, 2005 (for Model 767-200, -300, and -300F series airplanes); or Boeing Service Bulletin 767-25-0377, dated November 17, 2005 (for Model 767-400ER series airplanes); are considered acceptable for compliance with the corresponding actions specified in paragraph (f) of this AD.
