Turbomeca S.A. Arrius Models 2B, 2B1, and 2F Turboshaft Engines
Superseded. A later AD replaced this one: AD 2001-08-14 R1. Comply with the one in force.
This airworthiness directive (AD) is applicable to Turbomeca S.A. Arrius Models 2B, 2B1, and 2F turboshaft engines. These engines are installed on, but not limited to Eurocopter France Model EC120B and Eurocopter Deutschland EC135 T1 rotorcraft.
This amendment adopts a new airworthiness directive (AD), that is applicable to Turbomeca S.A. Arrius Models 2B, 2B1, and 2F turboshaft engines. This amendment requires the replacement of the right injector half manifold, left injector half manifold, and privilege injector pipe. This amendment 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 this 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 air path cracks, due to blockage of the fuel injection manifolds.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
