Abstract
We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This AD requires repetitive on-ground power cycles (resets) of the Transponder, Terrain and Traffic Collision Avoidance System (T3CAS). This AD was prompted by reports of spurious terrain ahead warning system (TAWS) alerts during approach and takeoff. We are issuing this AD to prevent spurious TAWS alerts, which could increase flightcrew workload during critical landing or takeoff phases, and result in reduced control of the airplane.
