What happened
During a night-time cargo operation, an aircraft was performing its final approach toward the runway at Kansas City Airport when the pilot encountered significant mechanical difficulties. As the flight progressed through the approach phase, the aircraft experienced engine-related complications which led to a loss of control. The plane subsequently impacted the ground several miles before reaching the runway. The impact resulted in the total destruction of the aircraft and one fatality involving the pilot.
Findings
Investigations into the accident identified several contributing elements that led to an uncontrolled collision with the terrain. The flight was operating in hazardous weather characterized by sleet, freezing rain, and icing conditions that were more severe than what had been previously forecasted. These environmental factors resulted in ice accumulation on both the airframe and the windshield.
Mechanical failures played a critical role in the loss of control. Specifically, the failure of the left vacuum pump occurred during the flight, which restricted the crew's ability to utilize de-icing equipment effectively. Additionally, the pilot failed to sustain the necessary flying speed during the approach. The combination of engine power issues caused by vacuum pump failure and the presence of heavy icing created a situation where the aircraft could no longer be safely operated.
