NTSB narrative
The pilot reported that he did not have the airplane configured properly for takeoff. During the takeoff roll from a field, he took his hand off the throttle to extend a notch of flaps. The throttle lever subsequently moved out and power was reduced. The pilot did not recognize the power reduction, or that the elevator trim was set to a nose down attitude before the airplane traveled off the runway, down an embankment, nosed over, and came to rest inverted. The airplane sustained substantial damage to both wings and the rudder. The pilot reported no mechanical failures or malfunctions that would have precluded normal operations.
Probable cause
The pilot's failure to ensure the airplane was configured for takeoff.

- 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.
