What the agency says
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH (AHD) Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, EC135T3, and EC635T2+ helicopters. This proposed AD was prompted by a report of a loss of the tail rotor controls due to a broken control rod of the yaw actuator. This proposed AD would require a one-time inspection of the ball pivot, yaw actuator assembly, and associated parts, and a repetitive inspection of the ball pivot. Depending on the inspection results, this proposed AD would require replacement of affected parts, further inspections, and application of new sealing compound. This proposed AD would also prohibit the installation of an affected part unless it is a serviceable part and certain requirements are met. The FAA is proposing this AD to address the unsafe condition on these products.
