The FAA proposes to supersede Airworthiness Directive (AD) 2020-11-05, which applies to all Airbus Helicopters Model EC120B helicopters. AD 2020-11-05 requires repetitive inspections of the tail rotor (TR) hub body for cracks and applicable corrective actions if necessary, and repetitive replacement of the attachment bolts, washers, and nuts of the TR hub body. This proposed AD would retain certain requirements of AD 2020-11-05, add repetitive inspections, require additional corrective actions, and update applicable service information. The FAA is proposing this AD to address the unsafe condition on these products.
