Airworthiness Directives; Safran Helicopter Engines, S.A. Engines

官方摘要

The FAA is superseding Airworthiness Directive (AD) 2023-15-03 for all Safran Helicopter Engines, S.A. (Safran) Model Arrius 2B2 engines. AD 2023-15-03 required 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 AD requires 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 issuing this AD to address the unsafe condition on these products.
