ACTION: Final rule. SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A320-251N, -252N, -253N, -271N, -272N, and -273N airplanes. This AD was prompted by a detected deviation to the manufacturing process of the angle fitting connection to side panel skin between certain frames (FR) at a certain stringer on both left hand (LH) and right hand (RH) sides. This AD requires inspecting the fastener holes to ensure they are the nominal diameter and applicable corrective actions. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective July 1, 2026. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of July 1, 2026. ADDRESSES: AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA-2025-5028; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this final rule, the mandatory continuing airworthiness information (MCAI), any comments received, and other information. The address for Docket Operations is U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE, Washington, DC 20590.

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 A320-251N, -252N, -253N, -271N, -272N, and -273N airplanes. The NPRM was published in the Federal Register on November 21, 2025 (90 FR 52570). The NPRM was prompted by EASA AD 2025-0065, dated March 27, 2025 (EASA AD 2025-0065) (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 a deviation to the manufacturing process was detected during a review of the cold working process in the assembly line. This deviation could adversely affect the fatigue life of the angle fitting connection to side panel skin between FR 35 and FR 36 at stringer 30 on both LH and RH sides. This could lead to crack initiatio…
