Department of Transportation Federal Aviation Administration • 14 CFR Part 39 • [Docket No. FAA-2024-0037; Project Identifier MCAI-2024-00027-R; Amendment 39-22664; AD 2024-01-52] • RIN 2120-AA64 AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule; request for comments. SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2023-24-51 which applied to all Hélicoptères Guimbal Model Cabri G2 helicopters. AD 2023-24-51 was prompted by reports of a crack in the pilot cyclic stick base and required repetitively inspecting certain part-numbered pilot and co-pilot cyclic stick bases and, depending on the results, corrective action. AD 2023-24-51 also prohibited installing those pilot and co-pilot cyclic stick bases unless certain requirements were met. Since the FAA issued AD 2023-24-51, more cracks in the cyclic stick bases have been reported, including a crack in a cyclic stick base that had accumulated only 700 hours time-in-service (TIS). This AD requires the same actions as AD 2023-24-51 but reduces the compliance time for performing the initial inspection. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA previously sent this AD as an emergency AD to all known U.S. owners and operators of these helicopters. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective February 21, 2024. Emergency AD 2024-01-52, issued on January 9, 2024, which contained the requirements of this amendment, was effective with actual notice. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of February 21, 2024. The FAA must receive comments on this AD by March 22, 2024. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to regulations.gov. Follow the instructions for submitting comments. • Fax: 202-493-2251. • Mail: U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE, Washington, DC 20590. • Hand Delivery: Deliver to Mail address above between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA-2024-0037; 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, any comments received, and other information. The street address for Docket Operations is listed above.
