2008-17-10 Boeing: Amendment 39-15648. Docket No. FAA-2008-0523; Directorate Identifier 2008-NM-049-AD. \n\nEffective Date \n\n\t(a) This airworthiness directive (AD) is effective October 2, 2008. \n\nAffected ADs \n\n\t(b) None. \n\nApplicability \n\n\t(c) This AD applies to Model 707-100 long body, -200, -100B long body, and -100B short body series airplanes; Model 707-300, -300B, - 300C, and -400 series airplanes; and Model 720 and 720B series airplanes, certificated in any category; as identified in Boeing 707 Special Attention Service Bulletin 3524, dated July 18, 2007. \n\nUnsafe Condition \n\n\t(d) This AD results from reports of cracks found in the wing to body terminal fittings during routine inspections. We are issuing this AD to prevent cracks and corrosion in the body terminal fittings, which could cause loss of support for the wing and could adversely affect the structural integrity of the airplane. \n\nCompliance \n\n\t(e) Comply with this AD within the compliance times specified, unless already done. \n\nInspections and Corrective Actions \n\n\t(f) Within 24 months after the effective date of this AD, do detailed inspections and applicable related investigative and corrective actions, by accomplishing all the actions specified in the Accomplishment Instructions of Boeing 707 Special Attention Service Bulletin 3524, dated July 18, 2007, except as provided by paragraph (g) of this AD. Repeat the detailed inspections thereafter at intervals not to exceed 24 months. Do all applicable related investigative and corrective actions before further flight. \n\t(g) If any crack or corrosion is found during any inspection required by paragraph (f) of this AD, and Boeing 707 Special Attention Service Bulletin 3524, dated July 18, 2007, specifies to contact Boeing for appropriate action: Before further flight, repair the terminal fittings using a method approved in accordance with the procedures specified in paragraph (i) of this AD. \n\nNo Information Submission\n\n\t(h) Although Boeing 707 Special Attention Service Bulletin 3524, dated July 18, 2007, specifies to submit information to the manufacturer, this AD does not include that requirement. \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, 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. \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. 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 707 Special Attention Service Bulletin 3524, dated July 18, 2007, 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, P.O.
