ACTION: Final rule. SUMMARY: The FAA is superseding four airworthiness directives (ADs) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211-535E4-37, RB211-535E4-B-37, and RB211-535E4-C-37 engines. The superseded ADs required recalculating the cyclic life for certain engine life-limited rotating parts and replacing those parts that have exceeded their cyclic life limit within specified compliance times. Since the FAA issued those ADs, the manufacturer has revised the engine time limits manual (TLM), introducing new and more restrictive instructions. This AD requires revising the airworthiness limitations section (ALS) of the existing approved maintenance or inspection program, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective June 27, 2024. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of June 27, 2024. ADDRESSES: AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA-2023-1652; 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.
