What the agency says
The FAA proposes to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model BR700-725A1-12 engines. This proposed AD was prompted by the manufacturer revising the airworthiness limitations section (ALS) of the existing time limits manual (TLM) to introduce new or more restrictive airworthiness limitations and associated thresholds and intervals for life-limited parts. This proposed AD would require revising the ALS of the operator's existing approved engine maintenance or inspection program, as applicable, to incorporate new or more restrictive instructions and associated thresholds and intervals for life-limited parts. The FAA is proposing this AD to address the unsafe condition on these products.
