Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Turbomeca Arriel 1 series turboshaft engines. This action requires the installation of a chip detector with electronic warning on the rear bearing oil return system. This amendment is prompted by reports of gas generator rear bearing failures. The actions specified in this AD are intended to prevent gas generator rear bearing failure, which could lead to an uncommanded engine shutdown.
