| Requirement: | 1. Carry out detailed inspections for damage to 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 in accordance with the Accomplishment Instructions of Boeing Service Bulletin (SB) 767-25-0376, Revision 1, dated 9 February 2007 (for Model 767-200, -300 and -300F series aeroplanes) or Boeing SB 767-25-0377, Revision 1, dated 9 February 2007 (for Model 767-400ER series aeroplanes); as applicable. |
| 2. Rectify any damage or deficiencies found during the Requirement 1 inspections. | |
| Actions accomplished before the effective date of this Directive in accordance with Boeing SB 767-25-0376, dated 17 November 2005 (for Model 767-200, -300 and-300F series aeroplanes) or Boeing SB 767-25-0377, dated 17 November 2005 (for Model 767-400ER series aeroplanes); are considered acceptable for compliance with the corresponding actions specified in this Directive. | |
| Later revisions of the above SB(s), approved by the United States Federal Aviation Administration (FAA) as an Alternate Method of Compliance (AMOC) to FAA AD 2007-16-18, are considered acceptable for compliance with the equivalent Requirements of this Directive. | |
| Note: FAA AD 2007-16-18 Amdt 39-15157 refers. | |
| Compliance: | For Requirement 1 - Within 36 months after the effective date of this Directive and thereafter repeat the inspections at intervals not to exceed 24,000 hours time in service or 72 months, whichever occurs first. |

| This Airworthiness Directive becomes effective on 25 October 2007. |
| Background: | This Directive requires repetitive detailed inspections of the wire bundles, PDU wiring and wire attaching hardware, supports and sleeving located in the forward and aft lower lobe cargo compartments, together with corrective actions as necessary. This Directive results from a fire in the forward lower lobe cargo compartment found shortly after aeroplane arrival. The Directive is issued 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. |
