Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2023-21-08, which applies to certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 1000 engines. AD 2023-21-08 requires revisions to the airworthiness limitation section (ALS) of the operator's existing approved aircraft maintenance program (AMP). Since the FAA issued AD 2023-21-08, the manufacturer revised the time limits manual (TLM) to introduce new or more restrictive tasks and limitations and associated thresholds and intervals for life-limited parts, which prompted this AD. This proposed AD would require revisions to the ALS of the operator's existing approved AMP, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
