1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by: a. Removing Airworthiness Directive (AD) 2017-18-05; Amendment 39-19014 (82 FR 41331, August 31, 2017); and b. Adding the following new AD: 2022-24-15 The Boeing Company: Amendment 39-22255; Docket No. FAA-2022-1054; Project Identifier AD-2022-00278-T. (a) Effective Date This airworthiness directive (AD) is effective January 26, 2023. (b) Affected ADs This AD replaces AD 2017-18-05; Amendment 39-19014 (82 FR 41331, August 31, 2017) (AD 2017-18-05). (c) Applicability This AD applies to all The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, 747SP, 747-8F, and 747-8 series airplanes, certificated in any category. (d) Subject Air Transport Association (ATA) of America Code 57, Wings. (e) Unsafe Condition This AD was prompted by a report of damage found at the lower trailing edge panels of the left wing and a broken fuse pin of the landing gear beam end fitting, and the determination that repetitive ultrasonic testing inspections of the fuse pin for cracking and optional repetitive replacement of certain corrosion-resistant (stainless) steel (CRES) and steel alloy fuse pins are necessary to address the unsafe condition. The FAA is issuing this AD to detect and correct cracking in the fuse pin of the wing landing gear beam end fitting. A broken fuse pin will not support the wing landing gear beam, causing damage to the surrounding structure, including flight control cables and hydraulic systems, which could result in loss of controllability of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions Except as specified by paragraph (h) of this AD: At the applicable times specified in paragraph 1.E., "Compliance," of Boeing Alert Service Bulletin 747-57A2360, Revision 1, dated February 9, 2022, do all applicable actions identified as "RC" (required for compliance) in, and in accordance with, the Accomplishment Instructions of Boeing Alert Service Bulletin 747-57A2360, Revision 1, dated February 9, 2022. (h) Exceptions to Service Information Specifications (1) Where the Compliance Time columns of the tables in the "Compliance" paragraph of Boeing Alert Service Bulletin 747-57A2360, Revision 1, dated February 9, 2022, use the phrase "the original issue date of this service bulletin," this AD requires using the date of October 5, 2017 (the effective date of AD 2017-18-05). (2) Where the Compliance Time columns of the tables in the "Compliance" paragraph of Boeing Alert Service Bulletin 747-57A2360, Revision 1, dated February 9, 2022, use the phrase "the Revision 1 date of this service bulletin," this AD requires using "the effective date of this AD." (i) Alternative Methods of Compliance (AMOCs) (1) The Manager, Seattle ACO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or responsible Flight Standards Office, as appropriate. If sending information directly to the manager of the certification office, send it to the attention of the person identified in paragraph (j) of this AD. Information may be emailed to: [email protected]. (2) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office. (3) An AMOC that provides an acceptable level of safety may be used for any repair, modification, or alteration required by this AD if it is approved by The Boeing Company Organization Designation Authorization (ODA) that has been authorized by the Manager, Seattle ACO Branch, FAA, to make those findings. To be approved, the repair method, modification deviation, or alteration deviation must meet the certification basis of the airplane, and the approval must specifically refer to this AD. (4) Except as specified by paragraph (h) of this AD: For service information that contains steps that are labeled as Required for Compliance (RC), the provisions of paragraphs (i)(4)(i) and (ii) of this AD apply. (i) The steps labeled as RC, including substeps under an RC step and any figures identified in an RC step, must be done to comply with the AD. If a step or substep is labeled "RC Exempt," then the RC requirement is removed from that step or substep. An AMOC is required for any deviations to RC steps, including substeps and identified figures. (ii) Steps not labeled as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program without obtaining approval of an AMOC, provided the RC steps, including substeps and identified figures, can still be done as specified, and the airplane can be put back in an airworthy condition.
