ACTION : Final rule. SUMMARY : The FAA is superseding Airworthiness Directive (AD) 2019–09– 03 and AD 2021–05–15 for certain Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. AD 2019–09–03 required a one-time inspection of the jettisoning mechanism of the cabin lateral sliding plug doors. AD 2021–05–15 required repetitive inspections, modifying the release system of each cabin lateral sliding plug door, or modifying the design of the jettison system of each cabin lateral sliding plug door. Since the FAA issued AD 2021–05–15, the manufacturer developed a prerequisite modification for certain helicopters, determined improved modification instructions were necessary for installation of the release system of the cabin lateral sliding plug door, and determined the compliance time could be extended. This AD requires modifying the release system of each cabin lateral sliding plug door or modifying the design of the jettison system of each cabin lateral sliding plug door as a terminating action for the repetitive inspections. The FAA is issuing this AD to address the unsafe condition on these products. DATES : This AD is effective August 3, 2026. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of August 3, 2026.

SUPPLEMENTARY INFORMATION : Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2019–09–03, Amendment 39–19637 (84 FR 22693, May 20, 2019) (AD 2019–09–03), and AD 2021–05–15, Amendment 39–21458 (86 FR 17290, April 2, 2021) (AD 2021– 05–15). AD 2019–09–03 and AD 2021– 05–15 applied to certain Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. AD 2019–09–03 required a one-time inspection of the jettisoning mechanism of the cabin lateral sliding plug doors. AD 2021–05–15 required repetitive inspections, modifying the release system of each cabin lateral sliding plug door, or modifying the design of the jettison system of each cabin lateral sliding plug door. The NPRM was published in the Federal Register on March 23, 2026 (91 FR 13794). The NPRM was prompted by EASA AD 2021–0139R1, May 10, 2023 (EASA AD 2021–0139R1) (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 the manufacturer received additional reports regarding the difficulty of installing the MOD 0725366 on certain helicopters, and the manufacturer developed MOD 0729230 as a prerequisite to installing MOD 0725366 for certain helicopter configurations. In addition, the manufacturer determined that the compliance time to incorporate the VerDate Sep<11>2014 16:37 Jun 26, 2026 Jkt 268001 PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 E:\FR\FM\29JNR1.SGM 29JNR1 lotter on DSK8BHNXB4PROD with RULES1

39006 Federal Register / Vol. 91, No. 123 / Monday, June 29, 2026 / Rules and Regulations modifications could be extended from within 1,100 flight hours or 27 months to within 1,325 flight hours or 40 months. In the NPRM, the FAA proposed to require modifying the release system of each cabin lateral sliding plug door or modifying the design of the jettison system of each cabin lateral sliding plug door as a terminating action for the repetitive inspections. The FAA is issuing this AD to prevent the jettison handle cable from interfering with the cable clamps, which could lead to jamming of the door jettisoning mechanism, preventing the jettisoning of the affected door in an emergency situation with possible obstruction of occupant evacuation. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2026–2720. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs. 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 issuing this AD to address the unsafe condition on these products. Except for minor editorial changes, 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 EASA AD 2021– 0139R1, which specifies procedures for inspecting the jettisoning mechanism of the left-hand (LH) and right-hand (RH) side of the cabin lateral sliding plug doors, and ensuring the cables are not contacting the cable clamps and accomplishing the applicable corrective actions. EASA AD 2021–0139R1 also specifies procedures for modifying the release system of each cabin lateral sliding plug door or modifying the design of the jettison system of each cabin lateral sliding plug door. EASA AD 2021–0139R1 specifies that the modification is a terminating action for the repetitive inspections and gives credit for the modification if it was accomplished using certain previously issued service material. 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 12 helicopters of U.S. registry. The FAA estimates the following costs to comply with this AD: E STIMATED C OSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Inspect cable clamps ............... 1 work hour × $85 per hour = $85 .................... $0 ......................... $85 ....................... $1,020. Modify the release .................... 214 work-hours × $85 per hour = $18,190 ....... Up to $122,500 .... Up to $140,690 .... Up to $1,688,280. Modify the jettison system ....... 214 work-hours × $85 per hour = $18,190 ....... Up to $122,500 .... Up to $140,690 .... Up to $1,688,280. 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 The FAA has determined that 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.
