Background
The airplane had been used for a charter flight and was not refueled upon return to its base. The accident pilot requested that the airplane be refueled, but this did not occur.
Pre-Flight Inspection
During the pilot's pre-flight inspection, he was distracted by activity around the airplane. This distraction may have hindered his ability to verify the fuel state.
The Flight
The subsequent flight was a personal weekend fishing trip. During the return leg, both engines quit. No evidence of fuel was found in the airplane at the crash site.
Fuel Endurance Calculation
The flight's endurance was calculated to be consistent with the fuel remaining in the airplane following the previous charter flight, indicating that fuel exhaustion likely occurred.
Investigation Findings
The investigation found that the airplane had not been refueled after the charter flight, and no visible fuel was present at the crash site.
