Adoption of the Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR Part 39 as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n\n\nSec. 39.13 (Amended) \n\n\n\n0 2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD) 2007-11-08, Amendment 39-15065 (72 FR 28594, May 22, 2007), and adding the following new AD: \n\n2013-24-15 The Boeing Company: Amendment 39-17692; Docket No. FAA- 2012-1069; Directorate Identifier 2012-NM-044-AD. \n\n(a) Effective Date \n\n\n\tThis AD is effective January 8, 2014. \n\n(b) Affected ADs \n\n\n\tThis AD supersedes AD 2007-11-08, Amendment 39-15065 (72 FR 28594, May 22, 2007). \n\n(c) Applicability \n\n\n\t(1) This AD applies to all The Boeing Company Model 727, 727C, 727-100, 727-100C, 727-200, and 727-200F series airplanes, certificated in any category. \n\t(2)This AD requires revisions to certain operator maintenance documents to include new actions (e.g., inspections) and/or Critical Design Configuration Control Limitations (CDCCLs). Compliance with these actions and/or CDCCLs is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (p) of this AD. The request should include a description of changes to the required actions that will ensure the continued operational safety of the airplane. \n\n(d) Subject \n\n\n\tAir Transport Association (ATA) of America Code 28, Fuel. \n\n(e) Unsafe Condition \n\n\n\tThis AD was prompted by a report of damage found to the sleeve, jacket, and insulation on an electrical wire during a repetitive inspection. We are issuing this AD to prevent chafing of the fuel boost pump electrical wiring and leakage of fuel into the conduit, and to prevent electrical arcing between the wiring and the surrounding conduit, which could result in arc-through of the conduit, and consequent fire or explosion of the fuel tank. \n\n(f) Compliance \n\n\n\tComply with this AD within the compliance times specified, unless already done. \n\n((Page 72793)) \n\n(g) Retained Compliance Times \n\n\n\tThis paragraph restates the requirements of paragraphs (f), (g), and (h) of AD 2007-11-08, Amendment 39-15065 (72 FR 28594, May 22, 2007). \n\t(1) For airplanes with 50,000 or more total flight hours as of June 28, 1999 (the effective date of AD 99-12-52, Amendment 39-11199 (64 FR 33394, June 23, 1999)): Within 20 days after June 28, 1999, accomplish the requirements of paragraph (h) of this AD. \n\t(2) For airplanes with less than 50,000 total flight hours, but more than 30,000 total flight hours, as of June 28, 1999 (the effective date of AD 99-12-52, Amendment 39-11199 (64 FR 33394, June 23, 1999)): Within 30 days after June 28, 1999, accomplish the requirements of paragraph (h) of this AD. \n\t(3) For airplanes with 30,000 total flight hours or less as of June 28, 1999 (the effective date of AD 99-12-52, Amendment 39-11199 (64 FR 33394, June 23, 1999)): Within 90 days after June 28, 1999, accomplish the requirements of paragraph (h) of this AD. \n\n(h) Retained Detailed Inspection, Corrective Action, and Installation \n\n\n\tThis paragraph restates the requirements of paragraph (i) of AD 2007-11-08, Amendment 39-15065 (72 FR 28594, May 22, 2007). \n\t(1) Perform a detailed inspection of the in-tank fuel boost pump wire bundles, and applicable corrective actions; and, except as provided by paragraph (i) of this AD, install sleeving over the wire bundles; in accordance with Boeing Alert Service Bulletin 727- 28A0126, dated May 24, 1999; Boeing Service Bulletin 727-28A0126, Revision 1, dated May 18, 2000; or Boeing Alert Service Bulletin 727-28A0132, dated February 22, 2007. \n\t(2) For the purposes of this AD, a detailed inspection is: An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity.
