What happened
The flight encountered an unexpected loss of engine power while it was on descent to its intended destination. The crew was forced to execute a landing on soft, uneven terrain due to the inability to maintain altitude or reach the airport.
Findings
A post-accident inspection of the aircraft revealed that only one quart of fuel remained in the system. There was no evidence of preexisting leaks from the fuel system, tanks, or fuel caps. The investigation determined that neither pilot had opened the fuel caps and inspected the quantity prior to departure.
The primary contributing factor was fuel exhaustion. The failure to verify fuel levels before takeoff led directly to the power loss and subsequent forced landing.
