## Abstract

We are adopting a new airworthiness directive (AD) for all Turbomeca S.A. Arrius 2F turboshaft engines. This AD requires a one- time inspection of the ejector assembly nozzle of an affected lubricating device and, if a discrepancy is found, removal and replacement with a part eligible for installation. This AD was prompted by an in-flight shutdown (IFSD) of an Arriel 1 engine. We are issuing this AD to prevent failure of the ejector assembly nozzle, which could lead to an IFSD of the engine, damage to the engine, and damage to the helicopter.
