AD FAA-2018-0184

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

Summary

We are adopting a new airworthiness directive (AD) for certain Safran Helicopter Engines, S.A., Arrius 2B1, 2B1A, 2B2, and 2K1 turboshaft engines. This AD requires inspecting the power turbine wheel (PTW) assembly and replacing the PTW if the turbine blade dampers are found missing. This AD was prompted by the manufacturer reporting a number of PTW assemblies may have been assembled without the blade dampers. We are issuing this AD to address the unsafe condition on these products.
