2009-20-09: Upper link fuse pins

2009-20-09 Boeing: Amendment 39-16032. Docket No. FAA-2008-1363; Directorate Identifier 2008-NM-104-AD. \n\nEffective Date \n\n\t(a) This airworthiness directive (AD) is effective November 5, 2009. \n\nAffected ADs \n\n\t(b) None. \n\nApplicability \n\n\t(c) This AD applies to Boeing Model 767-200, -300, and -300F series airplanes, certificated in any category; as identified in Boeing Alert Service Bulletin 767-54A0074, Revision 1, dated April 24, 2008. \n\nUnsafe Condition \n\n\t(d) This AD results from two reports of cracked upper link fuse pins. We are issuing this AD to prevent fatigue cracking or corrosion of the upper link fuse pin, which could result in failure of the fuse pin and consequent reduced structural integrity of the nacelle strut and possible separation of the strut and engine from the airplane during flight. \n\nCompliance \n\n\t(e) Comply with this AD within the compliance times specified, unless already done. \n\nInitial and Repetitive Inspections/Investigative and Corrective Actions \n\n\t(f) Inspect the upper link fuse pin of the nacelle struts for fatigue cracking and corrosion at the applicable time specified in Table 1 of this AD. Do the applicable inspection by doing all the applicable actions specified in the Accomplishment Instructions of Boeing Alert Service Bulletin 767-54A0074, Revision 1, dated April 24, 2008; and do all applicable related investigative and corrective actions before further flight. Repeat the applicable inspection at intervals not to exceed 3,000 flight cycles or 24 months, whichever is first, until the requirements of paragraph (g) of this AD have been done. \n\n\tTable 1--Compliance Times\n\n\n\nEngine Type\nAt the later of: initial inspection threshold\nGrace period\nJT9D\n14,000 total flight cycles\nWithin 3,000 flight cycles or 18 months after the effective date of this AD, whichever is first\nCF6-80A\n24,000 total flight cycles\nWithin 3,000 flight cycles or 18 months after the effective date of this AD, whichever is first\nPW4000\n8,000 total flight cycles\nWithin 3,000 flight cycles or 18 months after the effective date of this AD, whichever is first\nCF6-80C2\n10,000 total flight cycles\nWithin 3,000 flight cycles or 18 months after the effective date of this AD, whichever is first\nRB211\n24,000 total flight cycles\nWithin 3,000 flight cycles or 18 months after the effective date of this AD, whichever is first\n\n\tNote 1: The upper link inspections can be done with the pylon and/or engine in any position. \n\n\tNote 2: In paragraph 3.B, Steps 4.b.(1)(a) and 4.b.(2)(b)2){a{time} of the Accomplishment Instructions of Boeing Alert Service Bulletin 767-54A0074, Revision 1, dated April 24, 2008, the procedures specify to apply two layers of Boeing Material Specification (BMS) 10-11 primer to the inside surface of the fuse pin if no crack indication is found. However, two layers of primer are only necessary to touch up bare areas on the fuse pin if no crack indication is found. \n\nTerminating Action in AD 2000-19-09, Amendment 39-11910, and AD 2004- 16-12, Amendment 39-13768 \n\n\t(g) Accomplishment of the modification specified in paragraph (g)(1) or (g)(2) of this AD, as applicable, terminates the inspections required by paragraph (f) of this AD. \n\t(1) For Model 767 series airplanes powered by Rolls-Royce RB211 series engines, as identified in AD 2000-19-09: Modification of the nacelle strut and wing structure, as required by paragraphs (a) and (b) of AD 2000-19-09. \n\t(2) For Model 767-200, -300, and -300F series airplanes powered by Pratt & Whitney and General Electric engines, as identified in AD 2004-16-12: Modification of the nacelle strut and wing structure, as required by paragraphs (a), (b), (d), and (e) of AD 2004-16-12. \n\nCredit for Actions Done Using Previous Service Information \n\n\t(h) Inspection of the fuse pins before the effective date of this AD in accordance with Boeing Service Bulletin 767-54-0074, dated March 27, 1997, is acceptable for compliance with the inspections required by paragraph (f) of this AD if the inspections are accomplished without using an operator's equivalent procedure. Replacement of the fuse pins with new fuse pins before the effective date of this AD in accordance with Boeing Service Bulletin 767-54- 0074, dated March 27, 1997, is acceptable for compliance with the modification required by paragraph (g) of this AD. \n\nAlternative Methods of Compliance (AMOCs) \n\n\t(i)(1) The Manager, Seattle Aircraft Certification Office (ACO), FAA, ATTN: Berhane Alazar, Aerospace Engineer, Airframe Branch, ANM- 120S, FAA, Seattle ACO, 1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone (425) 917-6577; fax (425) 917-6590; has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. \n\t(3) An AMOC that provides an acceptable level of safety may be used for any repair required by this AD, if it is approved by an Authorized Representative for the Boeing Commercial Airplanes Delegation Option Authorization Organization who has been authorized by the Manager, Seattle ACO, to make those findings. For a repair method to be approved, the repair must meet the certification basis of the airplane, and the approval must specifically refer to this AD. \n\nMaterial Incorporated by Reference \n\n\t(j) You must use Boeing Alert Service Bulletin 767-54A0074, Revision 1, dated April 24, 2008; to do the actions required by this AD, unless the AD specifies otherwise. \n\t(1) The Director of the Federal Register approved the incorporation by reference of this service information under 5 U.S.C. 552(a) and 1 CFR part 51. \n\t(2) For service information identified in this AD, contact Boeing Commercial Airplanes, Attention: Data & Services Management, P.O.
