The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model EC130B4 and EC130T2 helicopters. This proposed AD was prompted by a report of cracks and geometrical non- conformities of the tail rotor blades (TRBs); all cracks initiated in the drain hole area at the blade root section. This proposed AD would require cleaning affected parts, visual and dye penetrant inspections for cracks of affected parts, a dimensional inspection to verify conformity of affected parts, and corrective actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
The agency’s own summary, as published.
