## Abstract

The FAA is adopting a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, and EC135T3 helicopters. This AD requires inspecting certain part-numbered actuators for corrosion, and removing them from service as necessary. This AD also requires reporting certain information to Airbus Helicopters. This AD is prompted by a hard landing of a helicopter and discovery of a ruptured and displaced tie bar inside the piston of the longitudinal single-axis actuator of the main rotor actuator (MRA). The actions of this AD are intended to address an unsafe condition on these products.
