Department of Transportation Federal Aviation Administration • 14 CFR Part 39 • [Docket No. FAA-2026-7227; Project Identifier MCAI-2025-01754-R] • RIN 2120-AA64 AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 2022-20-11, which applies to certain Bell Textron Canada Limited Model 429 helicopters. AD 2022-20-11 requires visually inspecting the external surface of the tail rotor (TR) gearbox support assembly, borescope inspecting or visually inspecting the inside of the tail boom, and performing a tactile inspection. Depending on the results of the inspections, AD 2022-20-11 requires removing certain rivets from service or repairing gaps in accordance with an approved method. Since the FAA issued AD 2022-20-11, the manufacturer determined the repetitive inspection interval needs to be reduced. This proposed AD would require the same actions as AD 2022-20-11 and would reduce the inspection interval. The FAA is proposing this AD to address the unsafe condition on these products. DATES: The FAA must receive comments on this NPRM by September 8, 2026. 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.
