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 certain The Boeing Company Model 757–200 and –300 series airplanes. The NPRM was published in the Federal Register on September 8, 2025 (90 FR 43159). The NPRM was prompted by an operator report indicating that during a maintenance H- check inspection, a crack was found at the splice fitting between the original wing and the Aviation Partners Boeing (APB) modified lower wing skin panel, which is spliced at wing station (WS) 711 on a Boeing Company Model 757– 200 airplane with the APB blended winglets installed in accordance with STC ST01518SE. APB reviewed the crack finding and determined the existing airworthiness limitations (AWL) structural significant items (SSI) 57–20–32B (which is required by AD 2020–01–18, Amendment 39–19824 ((85 FR 5304, January 30, 2020); corrected February 26, 2020 (85 FR 10969)) (AD 2020–01–18)) does not provide adequate probability of detection for foreseeable fatigue cracking of SSIs at WS 711. If cracks grow undetected, it may result in the inability of a principal structural element to sustain limit loads. The FAA determined that it is necessary to revise the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations for The Boeing Company Model 757–200 and –300 airplanes that have been modified in accordance with STC ST01518SE, with or without blended or scimitar blended winglets installed. In the NPRM, the FAA stated that incorporating the revision required by the proposed AD would terminate the requirements of paragraphs (g) and (h)(2) of AD 2020–01–18. In the NPRM, the FAA proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address fatigue cracking on the wing and winglet. This condition, if not addressed, could result in the inability of a principal structural element to sustain limit loads, which could adversely affect the structural integrity of the airplane. Discussion of Final Airworthiness Directive Comments The FAA received comments from three commenters, who supported the NPRM without change. The FAA received an additional comment from Aviation Partners Boeing (APB). The following presents the comment received on the NPRM and the FAA’s response to the comment. Request To Remove a Fax Number APB requested that the FAA remove the fax number listed for APB contact information in the Material Incorporated by Reference section and paragraph (l)(3) of the proposed AD. APB stated that it no longer has an active fax machine. The FAA agrees and has removed the fax number in the Material Incorporated by Reference section and paragraph (l)(3) of this AD accordingly. Conclusion The FAA reviewed the relevant data, considered any 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. Except for minor editorial changes, and any other changes described previously, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed Aviation Partners Boeing AP57.2–0604.2 Supplement to D622N001–9 (Sep 2020) 757 Maintenance Planning Data (MPD) Document Section 9 Airworthiness Limitations (AWLs) and Certification Requirements (CMRs) Boeing 757–200 with Winglets FAA STC Number ST01518SE and EASA STC Number 10015659, Revision February 2022; and Aviation Partners Boeing AP57.3– 0604.2 Supplement to D622N001–9 (Sep 2020) 757 Maintenance Planning Data (MPD) Document Section 9 Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs) 757–300 with Blended Winglets FAA STC ST01518SE and EASA STC Number 10015659, Revision August 2022.

This material provides the DTR check forms and the procedure for their use. 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 ADDRESSES section. Costs of Compliance The FAA estimates that this AD affects 156 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 work- hours per operator, although the agency recognizes that this number may vary from operator to operator. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, the FAA estimates the average total cost per operator to be VerDate Sep<11>2014 16:56 Apr 28, 2026 Jkt 268001 PO 00000 Frm 00051 Fmt 4700 Sfmt 4700 E:\FR\FM\29APR1.SGM 29APR1 lotter on DSK8BHNXB4PROD with RULES1

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.
