SummaryThe cargo aircraft's entry into an unusual attitude and the inability of the flight crew to analyze the flight condition before there was a complete loss of control. Although the precise reason for the loss of control was not identified, an undetermined failure of a component in the No.2 vertical gyro system, perhaps involving the amplifier and associated circuitry, probably contributed to the cause of the accident by incorrectly processing data to the co-pilot's approach horizon. The inflight structural failure of the aircraft was due to overload.
