Airworthiness Directives; Turbomeca S.A. Arrius Models 2B, 2B1, 2F Turboshaft Engines

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to Turbomeca S.A. Arrius Models 2B, 2B1, and 2F turboshaft engines. This proposal would require the replacement of the right injector half manifold, left injector half manifold, and privilege injector pipe with the engine installed on the helicopter. This proposal is prompted by reports from the Direction Generale de L'Aviation Civile (DGAC), which is the airworthiness authority for France, of partially or totally blocked fuel injection manifolds, which were found during inspections at a repair workshop. The actions specified by the proposed AD are intended to prevent engine flameout during rapid deceleration, or the inability to maintain the 2.5 minutes one engine inoperative (OEI) rating. The actions are also intended to prevent injector air path cracks, due to blockage of the fuel injection manifolds.
