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 Airbus SAS Model A320–211, –212, –214, –216, –231, –232, and –233 airplanes; and Model A321–111, –112, –131, –211, –212, –213, –231, and –232 airplanes. The NPRM was published in the Federal Register on May 4, 2026 (91 FR 23922). The NPRM was prompted by EASA AD 2025–0193, dated September 8, 2025 (EASA AD 2025–0193) (also referred to as the MCAI), issued by EASA, which is the Technical Agent for the Member States of the European Union. The MCAI states that during a fatigue test on a Model A320 airplane in support of the extended service goal (ESG) campaign, cracks were identified in the area of fastener holes at the forward and aft upper corner of the bulk cargo door at section 16 and 17, both left-hand (LH) and right-hand (RH) sides. This condition, if not addressed, could affect the structural integrity of the airplane. In the NPRM, the FAA proposed to require a rototest inspection for cracks and applicable on-condition actions, as specified in EASA AD 2025–0193. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2026–3879. Discussion of Final Airworthiness Directive Comments The FAA received and reviewed a comment that did not include a specific request to change the AD. This comment is outside the scope of this AD. Conclusion These products have been approved by the civil aviation authority of another country and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with this State of Design Authority, that authority has notified the FAA of the unsafe condition described in the MCAI referenced above. 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 VerDate Sep<11>2014 15:52 Aug 26, 2026 Jkt 268001 PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 E:\FR\FM\27AUR1.SGM 27AUR1 lotter on DSK8BHNXB4PROD with RULES1

55251 Federal Register / Vol. 91, No. 165 / Thursday, August 27, 2026 / Rules and Regulations 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 EASA AD 2025–0193 specifies procedures for a rototest inspection for cracks in the area of the fastener holes at the forward and aft upper corner of the bulk cargo door at section 16 and 17, both LH and RH sides, and applicable on-condition actions. On-condition actions include contacting the manufacturer for repair instructions and doing the repair if cracks are detected, or modifying the affected area by cold working the fastener holes if no crack is detected. 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 1,069 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: E STIMATED C OSTS FOR R EQUIRED A CTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 4 work-hours × $85 per hour = $340 .......................................................................................... $0 $340 $363,460 E STIMATED C OSTS OF O N-C ONDITION M ODIFICATION * Labor cost Parts cost Cost per product 4 work-hours × $85 per hour = $340 ...................................................................................................................... $0 $340 * The FAA has received no definitive data on which to base the cost estimates for the on-condition repairs specified in this AD. 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
