EASA 2019-0195

AD partially retains the requirements of EASA AD 2018-0248, which is superseded, and requires repetitive inspections of the tail rotor transmission assembly spindle bolts until the replacement of flapping hinge components starts and reduces the replacement compliance time for helicopters involved in high torque cycles per flight hour operations. It also requires operators to send back to Airbus Helicopters the removed flapping hinge components to support investigation of deterioration mechanism and scenario of those components.
