AD 2009-04-13 required revising the airworthiness limitations section (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. AD 2009-04-13 also required removing certain low-pressure compressor (LPC) (fan) disc assemblies from service and completing the Life Limited Part Tracking Sheet. Since the FAA issued AD 2009-04-13, the manufacturer has revised the engine time limits manual (TLM) to introduce new or more restrictive tasks and limitations and associated thresholds and intervals for life-limited parts. This AD requires revising the ALS of the 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. The FAA is issuing this AD to address the unsafe condition on these products.
