We propose to adopt a new airworthiness directive (AD) for all Turbomeca S.A. MAKILA 2A and MAKILA 2A1 turboshaft engines. This proposed AD was prompted by two occurrences of crack initiation on a ferrule of the diffuser. This proposed AD would require repetitive diffuser inspections and replacement of those diffusers that fail inspection. We are proposing this AD to prevent rupture of the ferrule of the diffuser, which could result in engine fire and damage to the helicopter.
