What happened
During the takeoff phase from Lexington-Blue Grass Airport, a left engine on the aircraft ignited. As the pilot attempted to execute a turn to return to the airport for an emergency landing, the flight crew lost control of the plane. The aircraft entered a steep dive and struck a field, where a large explosion occurred.
There were nine fatalities in the accident, including all occupants on board. The passengers included several medical professionals and scientists.
Findings
Investigations concluded that the aircraft experienced an uncontrolled descent following a fire within the left engine nacelle, though the specific origin of the fire remained undetermined. A significant contributing factor identified during the investigation was that the aircraft was improperly loaded at the time of the incident.
