NTSB narrative
The pilot of the amateur-built airplane elected to operate the airplane on the accident date with the fuel selector positioned to the right tank, and flew to a nearby airport where he performed an uneventful full-stop taxi-back landing. The pilot initiated takeoff with the fuel selector positioned to the right tank which was nearly empty and contrary to the Before Take Off checklist, and remained in the traffic pattern. While on the downwind leg abeam the approach end of the intended runway with another airplane on the extended downwind leg, the engine experienced a loss of power due to fuel starvation. He regained control of the airplane, which took 15 to 20 seconds, maintained best glide airspeed and then turned towards the runway. Unable to land on the runway, he maneuvered the airplane for a forced landing, but before ground contact he switched the fuel selector to the left tank position. Engine power was not restored and the airplane was substantially damaged during the off-airport forced landing. Postaccident examination revealed, a total of approximately 15 gallons of fuel in the left fuel tank, while the right fuel tank was empty. The fuel tanks were not breached and there was no evidence of fuel leakage at the scene.
Probable cause
A loss of engine power due to fuel starvation as a result of the pilot's incorrect positioning of the fuel selector valve.

- 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.
