What happened
Prior to the flight, the pilot conducted a visual inspection of the main fuel tanks. The fuel gauges indicated that each side was one-quarter full. While en route to the destination, the aircraft experienced a loss of power in one engine. Shortly thereafter, the second engine also lost power. Both engines failed due to fuel exhaustion.
The pilot had sufficient altitude to reach the airport. However, the landing was executed long and fast. The aircraft went off the end of the runway upon touchdown.
The investigation
The investigation confirmed that both engines lost power from fuel exhaustion. The pilot stated that he visually checked the main tanks before the flight. The fuel gauges indicated one-quarter full on each side.
Findings
The primary factor was fuel exhaustion. The pilot had sufficient altitude to reach the airport. The landing was long and fast. The aircraft went off the end of the runway.
