What happened
During a flight from Washington-Dulles Airport toward Dallas, the crew experienced mechanical issues involving the right engine. In response to the technical failure, the crew performed procedures to shut down the engine and feather the propeller. Following this incident, the flight was authorized to divert to Charleston-Kanawha Airport for an emergency landing.
As the aircraft approached runway 23, verbal interference from a pilot supervisor occurred during the landing sequence. The aircraft touched down 3,000 feet into the 5,600-foot runway. Due to insufficient remaining runway length, the plane could not stop in time and overran the pavement, eventually coming to a halt on a dirt bank where it caught fire. Although the aircraft was destroyed, all seven occupants managed to evacuate without injury.
Findings
While investigators were unable to identify the specific reason for the initial powerplant failure, the accident was attributed to the fact that the pilot-in-command misjudged the aircraft's speed and distance during the final landing phase.
