What happened
The pilot was conducting a flight operation when the engine ceased functioning while the aircraft was established on final approach to the runway. In response to the power loss, the pilot executed a forced landing procedure. During the rollout or impact sequence, the empennage of the airplane contacted the airport boundary fence. The aircraft subsequently collided with the terrain and came to rest in a nose-over attitude.
The investigation
Following the incident, an inspection of the fuel system was conducted to determine the cause of the power loss. Examination of the fuel tanks revealed that one tank was completely empty, while the other tank contained 25 gallons of fuel. It was noted that the pilot had just switched the fuel selector to the tank containing the remaining fuel immediately before the engine quit.
Findings
The sequence of events indicates a loss of engine power due to fuel starvation or exhaustion. Despite having fuel available in one tank, the engine failed to continue running after the selector was moved to that source, suggesting a potential issue with fuel flow or system integrity at that moment. The collision with the boundary fence and subsequent terrain impact were direct consequences of the forced landing maneuver necessitated by the engine failure.
