Airworthiness Directives; Airbus Model A300 B4-600, A300 B4-600R, and A300 F4-600R (Collectively Called A300-600), A310, A319, A320, A321, A330, and A340-200 and -300 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300-600, A310, A319, A320, A321, A330, and A340-200 and -300 series airplanes, that requires a one-time inspection to determine if certain Thales pitot probes are installed, a check for certain part numbers and serial numbers of the affected pitot probes, and cleaning of the drain hole of any affected pitot probes if obstructed. This action is necessary to prevent obstruction of the air intake of the pitot probes, which could result in misleading information being provided to the flightcrew. This action is intended to address the identified unsafe condition.
