Airworthiness Directives; Airbus Model A330-200 and A330-300 Series Airplanes; and Model A340-200 and A340-300 Series Airplanes

摘要

The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A330-200 and A330-300 series airplanes; and Model A340-200 and A340-300 series airplanes. This AD requires an accelerated schedule of repetitive testing of the elevator servo control loops, and corrective actions if necessary. This AD results from reports of failed elevator servo controls due to broken guides. We are issuing this AD to ensure proper functioning of the elevator servo controls. Failure of the elevator servo controls during certain phases of takeoff could result in an unannounced loss of elevator control and consequent reduced controllability of the airplane.
