NTSB narrative
The pilot reported that the engine stopped producing power shortly after takeoff. He initially tried to land on a road, but the engine momentarily re-started before it stopped completely. The pilot then made a forced landing to a corn field, which resulted in substantial damage to the right wing and airframe. Examination of the engine found water in the carburetor. The pilot stated that when he placed auto gas in the airplane's fuel tanks earlier that day, he used gas cans from his shop, which most likely contained water. He also did not sump the wing tanks prior to the flight.
Probable cause
The pilot's inadvertent addition of water into the fuel system and his improper preflight inspection, which resulted in a loss of engine power due to fuel contamination.

- 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.
