What it does

The FAA proposes to supersede Airworthiness Directive (AD) 2023-15-03, which applies to all Safran Helicopter Engines, S.A. (Safran) Model Arrius 2B2 engines. AD 2023-15-03 requires revising the airworthiness limitations section (ALS) of the existing engine maintenance manual (EMM) or instructions for continued airworthiness (ICA) and the existing approved maintenance or inspection program, as applicable, by incorporating the actions and associated thresholds and intervals, including life limits. Since the FAA issued AD 2023-15-03, the manufacturer has revised the ALS of the existing maintenance and overhaul manuals, introducing new and more restrictive instructions and maintenance tasks. This proposed AD would require updating the ALS of the existing EMM or ICA and the existing approved maintenance or inspection program, as applicable, by incorporating the actions and associated thresholds and intervals, including life limits. The FAA is proposing this AD to address the unsafe condition on these products.
