AD 2001-13-15 Airworthiness Directives; Boeing Model 757 Series Airplanes Equipped with Rolls Royce Engines

Models named: 757 series. Read the applicability below — it usually turns on serial or part numbers too.

Model 757 series airplanes, certificated in any category, equipped with Rolls Royce engines. Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (c) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

Required as indicated, unless accomplished previously. To prevent a short circuit that could result in either the possible ignition of fuel vapors in a flammable leakage zone or in the inability to stop the flow of fuel in the event of an engine fire, accomplish the following: Inspection/Corrective Action (a) Within 12 months after the effective date of this AD, accomplish paragraphs (a)(1) and (a)(2) of this AD. (1) Do a one-time detailed visual inspection of the wire bundles that pass through the three wire support brackets located at Power Plant Station (PPS) 278 on each engine strut, to find wire chafing. If any chafing is found, before further flight, repair the wire bundle per the Boeing Standard Wiring Practices Manual, Document D6-54446, Revision 23, dated August 1998. (2) Replace all three existing wire support brackets located at PPS 278 on each engine strut with new, improved wire support brackets, per Boeing Service Bulletin 757-54-0013, Revision 3, dated October 23, 1997, as revised by Boeing Information Notice 757-54-0013 IN 02, dated April 8, 1999. Note 2: For the purposes of this AD, a detailed visual inspection is defined as: “An intensive visual examination of a specific structural area, system, installation or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at intensity deemed appropriate by the inspector. Inspection aids such as mirror, magnifying lenses, etc., may be used. Surface cleaning and elaborate access procedures may be required.” Spares Paragraph (b) As of the effective date of this AD, no person shall install a wire support bracket having P/N 287N1112-8, -9, -20, or -21 on any airplane. Alternative Methods of Compliance (c) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Seattle Aircraft Certification Office (ACO), FAA. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Seattle ACO. Note 3: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Seattle ACO. Special Flight Permits (d) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished.
