NTSB narrative
While maneuvering, the engine and propeller stopped completely and a forced landing was executed into a bean field. On landing the airplane flipped over completely, coming to rest upright again, and was substantially damaged. The pilot reported entering a departure stall with full power which resulted in a relatively high pitch attitude. Immediately prior to the stall, the power was reduced to idle and the nose dropped rapidly as the aircraft stalled. The pilot reported that the aircraft may have experienced some rearward motion due to the high pitch attitude and abruptness of the stall. During the stall, the pilot stated that the engine and propeller both stopped completely. Attempts to start the propeller windmilling were not successful. The aerobatic engine had been modified to exhibit an "enhanced compression ratio", which increased propeller resistance to windmilling during the restart attempt. The amateur-built airplane did not have an engine starter installed. A post-accident engine examination revealed no anomolies determined to have existed prior the accident and/or attribuitable to the loss of power.
Probable cause
A loss of engine power for undetermined reasons.

- 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.
