NTSB narrative
The airplane nosed over during a forced landing in a field following a loss of engine power during the departure climb. The pilot manufactured the airplane, and it was undergoing its first test flight following the issuance of a Special Airworthiness Certificate. Approximately 10 minutes after takeoff the engine lost power. The pilot elected to land in a field. The landing forced debris into the wheel pants, which locked up the wheels. The airplane nosed over coming to rest inverted. Post accident examination of the engine by an FAA inspector revealed a fuel leak around the "B" nut that attached the aluminum fuel line to the throttle body. Removal of the nut and line revealed that the line cracked at the point of the flare. The builder had manufactured and installed this line.
Probable cause
the owner/builder's improperly fabricated and installed fuel line, which cracked at the point of the flare, resulting in a fuel leak and loss of engine power during the takeoff climb. A contributing factor was the soft terrain that jammed the landing gear wheels, nosing over the airplane during the ensuing forced landing.

- 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, coordinates. 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.
