Airworthiness Directives; Turbomeca Artouste III Series Turboshaft Engines

Zusammenfassung

The FAA is adopting a new airworthiness directive (AD) for Turbomeca Artouste III series turboshaft engines. This AD requires modification of the engine air intake assembly. This AD results from a report of an in-flight shutdown and subsequent loss of control of the helicopter due to ice ingestion into the engine. We are issuing this AD to prevent ice ingestion into the engine, which could lead to an in- flight shutdown and subsequent loss of control of the helicopter.
