Airworthiness Directives; Turbomeca S.A. Turboshaft Engines 

AGENCY: Federal Aviation Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new airworthiness directive (AD) for Turbomeca S.A. 

Arriel2D turboshaft engines. This AD was prompted by a low fuel pressure event caused L.J~ ... :J. -

by deterioration and a loss of the low-pressure drive function within the hydromechanical metering unit (HMU). This AD requires replacing the HMU at a reduced life. L _r '-

We are issuing this AD to prevent an uncommanded in-flight shutdown of the engine, 

and possible loss of the helicopter.
