ACTION: Final rule. SUMMARY: The FAA is adopting a new airworthiness directive (AD) certain Airbus Helicopters Model AS332C, AS332C1, AS332L, AS332L1, AS332L2, AS355E, AS355F, AS355F1, AS355F2, AS355N, AS355NP, AS-365N2, AS 365 N3, EC 155B, EC155B1, EC225LP, SA-365N, and SA-365N1 helicopters. This AD was prompted by a report of an unintentional activation of the hoist shear-button (shear-button) on the collective pitch handle during a night flight. This AD requires checking the operation of the shear-button safety-cap on each applicable collective pitch handle and prohibits installing certain part-numbered collective pitch handles or collective sticks with those part-numbered collective pitch handles installed unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective March 7, 2025. ADDRESSES: AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA-2024-2332; 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 Airbus Helicopters AS332C, AS332C1, AS332L, AS332L1, AS332L2, AS355E, AS355F, AS355F1, AS355F2, AS355N, AS355NP, AS-365N2, AS 365 N3, EC 155B, EC155B1, EC225LP, SA-365N, and SA-365N1 helicopters, with a collective pitch handle installed on a pilot or co-pilot collective stick having part number 704A41-1100-42, 704A41-1100-50, 704A41-1100-56, 704A41-1100-57, 704A41-1100-60, 704A41-1100-67, 704A41-1100-68, 704A41-1100-97, 704A41-1100-98, 704A41-1100-99, 704A41-1101-14, 704A41-1101-30, or 704A41-1101-32, as applicable to the model helicopter. The NPRM published in the Federal Register on October 16, 2024 (89 FR 83437). The NPRM was prompted by European Union Aviation Safety Agency (EASA) AD 2022-0220, dated November 16, 2022 (EASA AD 2022-0220) (also referred to as the MCAI), issued by EASA, which is the Technical Agent for the Member States of the European Union. The MCAI advises of a report of an inadvertent activation of the shear-button on a collective pitch handle occurring during a night flight when the pilot was turning on the headlight adjacent to the shear-button, which is protected by a safety-cap that is fitted with a spring. Additionally, the MCAI states that further investigation determined aging of the spring may have led to improper functioning of the safety-cap. In the NPRM, the FA…
