What happened
The pilot estimated the fuel requirements for the intended flight but made an error in calculation. Despite this assessment, he did not add any fuel to the airplane before departing. Approximately two hours into the flight, the aircraft experienced a complete loss of engine power. The pilot was forced to land off-airport, during which the nose gear struck uphill terrain.
The investigation
Following the accident, investigators examined the aircraft's fuel system. The examination revealed that only unusable fuel remained in the tanks, indicating that the engine had been starved of fuel during operation.
Findings
The primary factor contributing to this incident was the pilot's failure to properly calculate and provide adequate fuel for the flight. This oversight led directly to fuel exhaustion and the subsequent loss of power. The resulting forced landing caused damage to the nose gear due to the uneven terrain.
