What happened
During an active flight, the aircraft experienced a sudden loss of control. The plane entered a steep dive and struck the ground near Kansas City, where the impact triggered a massive explosion. There were five fatalities among the occupants of the aircraft.
Findings
Investigations into the accident identified that the aircraft underwent an uncontrolled descent due to a malfunction in the attitude gyro while in flight. Technical examination revealed that a section of vacuum hose had split, which contributed to the failure. Additionally, investigators discovered that a flow valve had become stuck in the closed position and noted evidence indicating that the gyro speed was insufficient for proper operation.
