Summary

The FAA is adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS355E, AS355F, AS355F1, and AS355F2 helicopters. This AD was prompted by multiple fatigue cracks in power turbine (PT) 3rd stage wheels. This AD requires revising the existing Rotorcraft Flight Manual (RFM) for your helicopter and installing a placard. The FAA is issuing this AD to address the unsafe condition on these products.
