## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to Turbomeca S.A. Arrius 1A turboshaft engines. This action requires replacement of the 10 main fuel injectors in Arrius 1A engines with new or overhauled injectors. This amendment is prompted by routine inspections conducted in the repair workshop demonstrating that some main fuel injectors were partially or totally blocked. The actions specified in this AD are intended to prevent blocked main fuel injectors that could lead to engine flameout during engine deceleration or that could prevent the engine from obtaining the 2\1/2\ minute one engine inoperative (OEI) power.
