Airworthiness Directive · Amendment 39-15766 · Boeing Model 757 Airplanes
Boeing Model 757 Airplanes
This AD applies to the airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category.
(1) Boeing Model 757-200, -200PF, and -200CB series airplanes, as identified in Boeing Special Attention Service Bulletin 757-28-0095, Revision 1, dated June 4, 2008.
(2) Boeing Model 757-300 series airplanes, as identified in Boeing Special Attention Service Bulletin 757-28-0096, Revision 1, dated June 4, 2008.
We are adopting a new airworthiness directive (AD) for certain Boeing Model 757 airplanes. This AD requires changing the wiring of the fuel boost pump and doing other specified actions. This AD results from reports of short circuits in an electrical connector at the wing-to- body electrical disconnect panel. We are issuing this AD to prevent a short circuit of the electrical connector for the fuel boost pump, which could cause the instruments for fuel, flap, slat, and aileron systems to malfunction and create a potential ignition source inside the fuel tanks. A potential ignition source inside the fuel tank in combination with flammable fuel vapors could result in a fuel tank explosion and consequent loss 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.
Within 60 months after the effective date of this AD, change the wiring of the fuel boost pump and do all other specified actions as applicable, by accomplishing all of the applicable actions specified in the Accomplishment Instructions of Boeing Special Attention Service Bulletin 757-28- 0095 (for Model 757-200, -200PF, and -200CB series airplanes) or 757-28-0096 (for Model 757-300 series airplanes), both Revision 1, both dated June 4, 2008; as applicable. The other specified actions must be done before further flight after changing the fuel boost pump wiring. Actions accomplished before the effective date of this AD in accordance with Boeing Special Attention Service Bulletin 757-28-0095 or 757-28-0096, both dated June 18, 2007, are considered acceptable for compliance with the corresponding actions in this paragraph.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
