Airworthiness Directives; British Aerospace Model ATP Airplanes
This amendment adopts a new airworthiness directive (AD), applicable to certain British Aerospace Model ATP airplanes, that requires modification of the power supply for the communications system. This amendment is prompted by reports of loss of power to the communications system due to an electrical fault in the ground crew jack box or the handset of the public address (PA) system. The actions specified by this AD are intended to prevent the inability of the flight crew to communicate with passengers via the PA system and with air traffic control due to loss of power to the communication system, which may lead to unsafe operation of the airplane.
