ACTION: Final rule. SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by reports of the passenger door failing to dampen during opening at regularly scheduled maintenance checks, causing the door to open more rapidly than normal. An investigation found that a contributing factor was erroneous aircraft maintenance manual (AMM) procedures. This AD prohibits using certain versions of certain AMM tasks for the passenger door. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective January 13, 2023. ADDRESSES: AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA-2022-0995; 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 Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published in the Federal Register on August 12, 2022 (87 FR 49799). The NPRM was prompted by AD CF-2021-41, dated November 24, 2021, issued by Transport Canada, which is the aviation authority for Canada (referred to after this as the MCAI). The MCAI states that there have been reports of the passenger door failing to dampen during opening at regularly scheduled maintenance checks, causing the door to open more rapidly than normal. An investigation found that a contributing factor was erroneous AMM procedures. In the NPRM, the FAA proposed to prohibit using certain versions of certain AMM tasks for the passenger door. The FAA is issuing this AD to prevent rapid opening of the passenger door, which can result in damage to the door and consequent injury to maintenance personnel. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA-2022-0995.
