Incident Overview
The pilot reported that the aircraft experienced fuel exhaustion after being in flight for slightly more than three hours following a refueling. During the flight, the engine had reportedly been leaned. Post-accident examination of the aircraft revealed no evidence of any leaks in the fuel system. The aircraft has an endurance of approximately 4.8 hours, according to specifications, but the exact reason for the fuel exhaustion could not be determined.
Forced Landing and Ground Loop
A forced landing was executed in a field at night. To avoid striking a dirt bank, the pilot intentionally ground looped the aircraft. Ground looping involves a sharp turn on the ground, often to prevent a collision or to minimize damage. The maneuver was successful in avoiding the dirt bank.
Investigation Findings
Investigators noted that the aircraft was fueled before the flight and that the pilot's statement indicated the flight duration was just over three hours until fuel exhaustion. Despite the aircraft's advertised endurance of roughly 4.8 hours, the fuel was exhausted prematurely. No mechanical issues with the fuel system were identified, leaving the cause undetermined.
