A twin-engine aircraft crashed near Jackson, Mississippi, while attempting an emergency diversion following an engine malfunction in icing conditions.

What happened

A demonstration flight traveling from Montgomery, Alabama, to Tulsa, Oklahoma, ended in a fatal accident near Jackson Municipal Airport. The twin-engine aircraft was operating at 14,000 feet when the pilot encountered engine issues while flying through icing conditions. After notifying air traffic control of an engine failure, the crew received clearance to divert to the nearby Jackson airport.

During the descent toward the diversion airfield, the aircraft became uncontrollable and struck the ground a short distance from the airport. The impact resulted in the destruction of the plane and caused eight fatalities, including the pilot and seven passengers.

Findings

Investigations into the accident identified several contributing elements related to the weather and the mechanical failure. The flight was operating within an area containing sleet, freezing rain, and fog. Although the weather briefing had indicated a freezing level between 13,000 and 15,000 feet, the aircraft was cruising at 14,000 feet during the onset of the emergency.

Key factors identified in the crash include:

  • The complete failure of one engine
  • Distraction from flight controls due to the emergency
  • Inappropriate decision-making during the flight
  • Severe weather conditions including icing and low visibility

Probable cause

The aircraft struck the ground in an uncontrolled manner during its final approach following a powerplant failure.
