RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Final rule.
 SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767-300 series airplanes. This AD was prompted by report that some Model 767-300 series airplanes that had been converted into a freighter configuration are missing an electrical bracket for a wire bundle in the main equipment center. This AD requires installing an electrical support bracket and re-installing wire bundles. The FAA is issuing this AD to address the unsafe condition on these products.
 DATES: This AD is effective October 15, 2024. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of October 15, 2024.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to The Boeing Company Model 767-300 airplanes with certain line numbers. The NPRM published in the 
                    **Federal Register**
                     on April 23, 2024 (89 FR 30284). The NPRM was prompted by a report that some Model 767-300 series airplanes that had been modified to operate in a freighter configuration by the manufacturer are missing an electrical support bracket for a wire bundle in the main equipment center. The missing electrical support bracket affects wire separation configuration requirements for fuel quantity indicating system wiring and could result in an electrical fault condition. In addition, the missing electrical support bracket is needed for some Model 767-300 cargo airplanes to accomplish the service bulletin required by the alternative actions in paragraph (h)(2)(ii) of AD 2020-18-16, Amendment 39-21237 (85 FR 62993, October 6, 2020). In the NPRM, the FAA proposed to require installing an electrical support bracket and re-installing wire bundles. The FAA is issuing this AD to prevent possible ignition sources in the fuel tank due to an electrical fault, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. Discussion of Final Airworthiness Directive Comments The FAA received comments from two commenters. The Air Line Pilots Association, International, supported the NPRM without change. Aviation Partners Boeing stated that installing winglets under Supplemental Type Certificate ST01920SE does not affect compliance with the proposed actions. The FAA agrees. The FAA has not changed this AD in this regard. Conclusion The FAA reviewed the relevant data, considered the comments received, and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. This AD is adopted as proposed in the NPRM. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed Boeing Alert Service Bulletin 767-24A0261, Revision 1, dated August 17, 2022. This material specifies procedures for installing an electrical support bracket in the main equipment center and re-installing wire bundles. This material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the

 Authority for This Rulemaking Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency's authority. The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: General requirements. Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify that this AD: (1) Is not a “significant regulatory action” under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and (3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

(e) Unsafe Condition This AD was prompted by a report that some Model 767-300 series airplanes that have been modified to operate in a freighter configuration are missing an electrical bracket for a wire bundle in the main equipment center, which affects wire separation configuration requirements for fuel quantity indicating system wiring and could result in an electrical fault condition. The FAA is issuing this AD to prevent possible ignition sources in the fuel tank due to an electrical fault, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions Except as specified in paragraph (h) of this AD: At the applicable times specified in the “Compliance” paragraph of Boeing Alert Service Bulletin 767-24A0261, Revision 1, dated August 17, 2022, do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of Boeing Alert Service Bulletin 767-24A0261, Revision 1, dated August 17, 2022.

                            *AMOC@faa.gov.* (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, AIR-520, Continued Operational Safety 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 material that contains steps that are labeled as Required for Compliance (RC), the provisions of paragraphs (j)(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.
