What happened
While operating at a cruise altitude of 25,000 feet, the pilot experienced a failure of the right engine. Roughly one minute after the initial failure, the left engine also ceased operation. In response to the loss of power, the pilot began a steep descent with the intention of descending below 18,000 feet. Despite efforts to restart the left engine, the crew was unable to restore power.
The pilot proceeded to land the aircraft on a runway measuring 1,900 feet in length. The aircraft came to a stop 500 feet down the runway, but the momentum caused the plane to run off the departure end of the pavement. The aircraft ultimately came to rest 300 feet beyond the runway threshold in a wooded area.
Findings
Post-accident inspections revealed that 130 gallons of fuel remained in the main tanks at the time of the incident. Laboratory testing confirmed that the fuel contained no water, and investigators found that the fuel lines were unobstructed and the fuel pumps were functional. While the right engine performed satisfactorily during subsequent test runs, investigators identified a failed torque sensor on the left engine. This specific component failure was capable of disconnecting the fuel pump driven by the left engine.
