ACTION: Final rule. SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2013-05-13 for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-710 series turbofan engines. AD 2013-05-13 required replacing the affected fuel pump splined couplings. Since the FAA issued AD 2013-05-13, the manufacturer has revised the time limits manual (TLM), introducing new and more restrictive instructions, including the replacement of the fuel pump splined coupling. This AD is prompted by service experience that demonstrated premature wear of the splined coupling on the fuel pump and subsequent manufacturer revision of the TLM to incorporate revised life limits and updated mandatory inspection intervals, including replacement of the fuel pump splined coupling. This AD expands the applicability by adding a model turbofan engine and also requires revisions to the airworthiness limitations section (ALS) of the operator's existing approved aircraft maintenance program (AMP), 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 January 27, 2023. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of January 27, 2023.
