FAA Grounds Safran Helicopter Blades Over Tiny Flaws
Published Date: 3/13/2025
Proposed Rule
Summary
If you own a Safran ARRIUS 2F or 2R helicopter engine, listen up! The FAA wants you to swap out some high-pressure turbine blades because they might have tiny flaws from a recent manufacturing change. This fix needs to happen soon to keep your engine safe and flying smoothly, and it could cost some money but is super important for safety.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
Required HP turbine blade replacements
The FAA proposes an airworthiness directive that would require replacement of affected high‑pressure (HP) turbine blades on all Safran Model ARRIUS 2F and ARRIUS 2R engines. The replacements must be done as specified in a European Union Aviation Safety Agency (EASA) AD that the FAA is incorporating by reference, which will impose maintenance actions and related costs on engine owners or operators.
Fix for unsafe turbine blade porosity
The FAA says certain HP turbine blades may have non-compliant porosity rates due to a manufacturing change, creating an unsafe condition. The proposed AD is intended to address that unsafe condition on Safran ARRIUS 2F and 2R engines by requiring specified corrective action.
