NTSB narrative
The pilot reported that he was departing from a remote, off-airport site in an experimental amateur-built airplane. He stated that just after takeoff, as the airplane reached about 50 feet above ground level, the engine lost all power. The pilot then attempted to land the airplane near the departure end of the site, but, with insufficient airspeed or altitude to transition to a landing attitude, the airplane landed hard and sustained substantial damage to the wings and fuselage. According to the pilot, he had turned the airplane's fuel valves to the "off" position after the previous landing, and he failed to move the fuel valves into the "on" position before departure. He also noted that he did not use the preflight checklist. The pilot stated that there were no preaccident mechanical anomalies with the airplane that would have precluded normal operation.
Probable cause
The pilot’s improper positioning of the fuel selector valves, which resulted in a loss of engine power due to fuel starvation. Contributing to the accident was the pilot’s failure to follow preflight checklists.

- 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.
