B-2 Accident Report Released
Distorted data introduced by a B-2's air data system skewed information entering the bomber's flight control computers ultimately causing the crash of the aircraft on takeoff at Andersen Air Force Base, Guam, Feb. 23, according to an Air Combat Command accident investigation report released yesterday.
Moisture in the aircraft's Port Transducer Units during air data calibration distorted the information in the bomber's air data system, causing the flight control computers to calculate an inaccurate airspeed and a negative angle of attack upon takeoff. According to the report, this caused an, "uncommanded 30 degree nose-high pitch-up on takeoff, causing the aircraft to stall and its subsequent crash."
