NTSB narrative
The pilot did not visually check the fuel level prior to departure, but his fuel gauges indicated the left tank was 3/4-full and the right fuel tank was 1/4-full. He departed with the fuel selector on the left tank and flew for an hour before he picked up a friend and continued with the flight. The pilot and his passenger flew to another airport and landed. They then taxied back to the runway and departed. During takeoff, the pilot made a left hand turn and the engine began to sputter and then stopped producing power. The pilot was unable to return to the airport, and made a forced landing to a field. Examination of the airplane revealed the left fuel tank was empty and the right tank had only residual fuel inside.
Probable cause
The pilot's improper fuel management, which resulted in a loss of engine power due to fuel exhaustion.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
