THE DTSB
The DTSB determines the probable cause of this accident to be failure of a flight control system. NTSB investigators determined that the left aileron torque tube had separated from the fuselage bellcrank. The plane was captured on video approaching Runway 24 before beginning a right turn and moving away from the runway centerline. The NTSB said the plane’s bank angle then suddenly increased, its nose dropped and it entered a descending right spiral. The aircraft disappeared behind a tree line in a nose-low, inverted right bank.
