Airworthiness Directives; Airbus Model A300 B2 and B4 Series Airplanes

The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A300 B2 and B4 series airplanes. This AD requires repetitive replacement of the angle of attack (AOA) sensors with new or overhauled AOA sensors. This AD also provides an optional terminating action for the repetitive replacements. This AD results from reports of several false stall warnings associated with stick-shaker activation, occurring during take-off. We are issuing this AD to prevent false stall warnings associated with stick-shaker activation, which could result in increased pilot workload as the pilot tries to determine the cause of the stall warning and possible reduction in the pilot's ability to control the airplane.
