The FAA proposes to supersede Airworthiness Directive (AD) 2023-15-03, which applies to all Safran Helicopter Engines, S.A. Model Arrius 2B2 engines. The proposed AD requires updating the airworthiness limitations section (ALS) of the existing engine maintenance manual or instructions for continued airworthiness and the existing approved maintenance or inspection program by incorporating new and more restrictive actions, thresholds, intervals, and life limits. This action addresses an unsafe condition to prevent failure of life-limited parts that could result in engine failure, loss of thrust control, and loss of the helicopter. Comments on the proposal are due by August 24, 2026.
