AD 2021-25-03 required operators to revise the airworthiness limitation section (ALS) of their existing approved continuous airworthiness maintenance program by incorporating the revised tasks of the applicable time limits manual (TLM) for each affected engine model. Since the FAA issued AD 2021-25-03, the manufacturer again revised the TLM to introduce new or more restrictive tasks and limitations and associated thresholds and intervals for life-limited parts, which prompted this AD. This AD requires revising the ALS of the operator's existing approved engine maintenance or inspection program, as applicable, to incorporate new or more restrictive tasks and limitations and associated thresholds and intervals for life-limited parts, 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. </SUM> <EFFDATE> <HD SOURCE="HED">DATES:</HD> This AD is effective May 21, 2024. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of May 21, 2024. </EFFDATE> <HD SOURCE="HED">ADDRESSES:</HD> <E T="03">AD Docket:</E> You may examine the AD docket at <E T="03">regulations.gov</E> under Docket No. FAA- [...
