The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757 airplanes. This AD requires inspecting certain power feeder wire bundles for damage, inspecting the support clamps for these wire bundles to determine whether the clamps are properly installed, and performing corrective actions if necessary. This AD results from a report that a power feeder wire bundle chafed against the number six auxiliary slat track, causing electrical wires in the bundle to arc, which damaged both the auxiliary slat track and power feeder wires. We are issuing this AD to prevent arcing that could be a possible ignition source for leaked flammable fluids, which could result in a fire. Arcing could also result in a loss of power from the generator connected to the power feeder wire bundle, and consequent loss of systems, which could reduce controllability of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
The term “service bulletin,” as used in this AD, means the Accomplishment Instructions of the following service bulletins, as applicable:
(1) For Model 757-200, -200PF, and -200CB series airplanes: Boeing Special Attention Service Bulletin 757-24-0105, Revision 2, dated April 20, 2006; and
(2) For Model 757-300 series airplanes: Boeing Special Attention Service Bulletin 757-24-0106, Revision 2, dated April 20, 2006.
Within 24 months after the effective date of this AD, perform a general visual inspection for damage (including but not limited to chafing) of power feeder wire bundles W3312 and W3412 at front spar station 148.90 in the left and right wings, and a general visual inspection of the support clamps for those power feeder wire bundles to determine whether the clamps are properly installed, and, before further flight, do all applicable corrective actions. Do these actions by doing all of the applicable actions in the applicable service bulletin.
Inspections and corrective actions done before the effective date of this AD in accordance with the service information listed in Table 2 of this AD are acceptable for compliance with the corresponding actions required by this AD.
