Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Model A300 B2 and B4 series airplanes. This proposed AD would require an inspection to determine the part number of all angle of attack (AOA) sensors, and repetitive replacement of the AOA sensors with new or overhauled AOA sensors if necessary. This proposed AD would also provide an optional terminating action for the repetitive replacements. This proposed AD is prompted by reports of several false stall warnings associated with stick-shaker activation, occurring during take-off. We are proposing 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.
