2008-22-06 Boeing: Amendment 39-15701. Docket No. FAA-2007-0344; Directorate Identifier 2007-NM-149-AD. \n\nEffective Date \n\n\t(a) This airworthiness directive (AD) is effective December 17, 2008. \n\nAffected ADs \n\n\t(b) None. \n\nApplicability \n\n\t(c) This AD applies to Boeing Model 767-200 and -300 series airplanes, certificated in any category; as identified in Boeing Alert Service Bulletin 767-28A0064, Revision 2, dated October 27, 2005. \n\nUnsafe Condition \n\n\t(d) This AD results from operator inspections of the Fuel Quantity Indicating System (FQIS) wire bundles that revealed corrosion at the connections between the ground wire and shield of each of the four FQIS wire bundles. We are issuing this AD to prevent this corrosion, which could reduce system protection of the lightning shield and result in loss of the electrical grounding between the lightning shield and the airplane structure. This condition, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. \n\nCompliance \n\n\t(e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. \n\nReplacement \n\n\t(f) Within 36 months after the effective date of this AD: Replace the wire segments of the four FQIS wire bundles with new, improved wire segments, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 767-28A0064, Revision 2, dated October 27, 2005. \n\nCredit for Actions Done Using Previous Service Information \n\n\t(g) Actions accomplished before the effective date of this AD in accordance with Boeing Alert Service Bulletin 767-28A0064, Revision 1, dated February 21, 2002, are considered acceptable for compliance with the corresponding actions specified in this AD. \n\nAlternative Methods of Compliance (AMOCs) \n\n\t(h)(1) The Manager, Seattle Aircraft Certification Office (ACO), FAA, ATTN: Philip Sheridan, Aerospace Engineer, Systems and Equipment Branch, ANM-130S, FAA, Seattle ACO, 1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone (425) 917-6441; fax (425) 917-6590; has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. \n\t(2) To request a different method of compliance or a different compliance time for this AD, follow the procedures in 14 CFR 39.19.
