Department of Transportation Federal Aviation Administration • 14 CFR Part 39 • [Docket No. FAA-2026-7209; Project Identifier MCAI-2025-00629-E] • RIN 2120-AA64 ( printed page 40900) AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 2009-04-13, which applies to certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 engines. AD 2009-04-13 requires 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 requires 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 proposed AD would require 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 proposing this AD to address the unsafe condition on these products. DATES: The FAA must receive comments on this NPRM by August 20, 2026.
