Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France) Helicopters

摘要

We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS332L2 helicopters with a certain yaw control damper support (support) installed. This AD requires repetitively inspecting the support attachment points for a crack. This AD is prompted by a report that the front attachment points of several supports were found to have cracks. These actions are intended to detect a crack in a support, which could result in failure of the support, separation of the yaw damper unit, blocking of the yaw flight control channel, and reduced control of the helicopter.
