## Abstract

We are adopting a new airworthiness directive (AD) for all Safran Helicopter Engines, S.A., Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, and 1S1 turboshaft engines. Emergency AD 2017-04-51 was sent previously to all known U.S. owners and operators of these engines. This AD requires inspecting, wrapping, and replacing the affected drain valve assembly (DV) installed on these Arriel 1 engines. This AD was prompted by reports of fuel leaks originating from the DV on certain Arriel engines. We are issuing this AD to correct the unsafe condition on these products.
