Turbomeca S.A. Arriel -1B, -1D, and -1D1 Series Turboshaft Engines
This airworthiness directive (AD) is applicable to Turbomeca S.A. Arriel -1B, -1D, and -1D1 series turboshaft engines. These engines are installed on, but not limited to Eurocopter AS-350B "Astar" helicopters.
This amendment adopts a new airworthiness directive (AD) that is applicable to Turbomeca S.A. Arriel -1B, -1D, and -1D1 series turboshaft engines. This amendment requires replacement of modules M03 modified to TU 204 standard with modules M03 not modified to TU 204 standard. This amendment is prompted by several reports of 2nd stage gas generator turbine blade failures. The actions specified by this AD are intended to prevent 2nd stage gas generator turbine blade failure resulting in uncommanded engine in-flight shutdown.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
