AD NUMBER: 2015-10-07

PRODUCT: All Turbomeca S.A. Arrius 2F turboshaft engines.

ACTION: Final Rule; request for comments

SUMMARY: The FAA is superseding airworthiness directive (AD) 2014-01-01 for the product listed above. AD 2014-01-01 required a one-time inspection of the ejector assembly nozzle of certain serial number (S/N) lubricating devices and, if a discrepancy was found, removal and replacement of the affected ejector assembly nozzle with a part eligible for installation.

This AD requires the same action as AD 2014-01-01 and expands the list of affected S/N lubricating devices. This AD was prompted by the determination that additional lubricating devices, identifiable by S/N, may have an incorrect bonding of the nozzle on the ejector assembly.

The FAA is issuing this AD to prevent failure of the ejector assembly nozzle, which could lead to an in-flight shutdown (IFSD) of the engine, damage to the engine, and damage to the helicopter.

DATES: This AD is effective June 12, 2015. Comments must be received by July 13, 2015.
