Accident Summary
The airplane overran the end of runway 12 and encountered a ravine. The pilot reported that the airplane had lost all electrical power while in cruise flight. During the approach, the pilot observed an airplane taxi onto the runway. He decided to land over that airplane and touched down approximately three-quarters of the way down the runway. The flaps were not available because of the electrical failure. The airplane subsequently overran the end of the runway.
Pilot Report
The pilot stated that the loss of electrical power occurred during cruise flight. While on final approach, another airplane taxied onto the runway. The pilot chose to continue the landing and land over the other aircraft, resulting in a touchdown well beyond the normal touchdown point. The absence of flaps, due to the electrical failure, likely increased the landing distance.
Post-Accident Inspection
Following the accident, the Safety Board investigator-in-charge (IIC) performed a normal start of the engine using an auxiliary power unit. The engine started without hesitation and ran at various power settings with no anomalies. Inspection of the electrical system revealed that the alternator had an open field, which led to the complete discharge of the electrical system.
