In January 1963, the CAB released its aircraft accident report stating that the "most likely abnormality" to have caused the crash was a short circuit caused by wires in the automatic piloting system that had been damaged in the manufacturing process. It stated that the probable cause of the accident was "...rudder control system malfunction producing yaw, sideslip, and roll leading to a loss of control from which recovery was not effective" and concluded "that a rudder servo malfunction due to shorted wires is the most likely abnormality to have produced the accident."
