NTSB narrative
The pilot reported that he was performing a test flight in the experimental airplane after completing a modification to the pitch control system. While on downwind to land at the private airstrip, the engine lost partial power. During the base to final turn, about 300 ft above ground level, the airplane exceeded its critical angle of attack, which resulted in an aerodynamic stall and loss of airplane control at an altitude too low to allow for recovery. The airplane impacted a cornfield short of the private airstrip and sustained substantial damage to the fuselage and both wings. The pilot reported that there were no preimpact mechanical malfunctions or failures that would have precluded normal operation. The pilot stated that the partial loss of engine power was due to an excessive fuel pressure to the carburetor because he forgot to open a valve that bypassed fuel around the fuel pump that is used for engine priming and starting.
Probable cause
The pilot’s exceedance of the airplane’s critical angle of attack in the traffic pattern, which resulted in an aerodynamic stall and loss of airplane control at too low of an altitude to recover. Contributing to the accident was the partial loss of engine power due to improper management of the fuel system.

- 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, cause areas. 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.
