NTSB narrative
The commercial pilot reported that, after he climbed the non-certificated, experimental airplane to 300 to 400 ft above ground level after takeoff, there was a partial loss of engine power. The engine continued to operate but was unable to produce adequate power to sustain flight. The pilot attempted to land in a field near a residential area and the airplane impacted a fence, which resulted in substantial damage to the wings and fuselage. The fuel in the airplane had not been changed for about 12 months before the accident; however, a limited examination of the wreckage determined that the fuel onboard the airplane tested negative for water. The airplane was manufactured in 2001 and never received an airworthiness certificate. The postaccident examination was limited and the reason for the loss of power was not determined.
Probable cause
A partial loss of engine power for reasons that could not be determined based on the available information.

- 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.
