NTSB narrative
According to the pilot, while en route to his destination airport he decided to land on a sandbar in a nearby river. After touching down on the sandbar, the pilot realized that the available stopping distance was less than he had thought, so he applied hard braking in order to stop the airplane. During the braking sequence the airplane nosed over onto its back, resulting in substantial damage to the top portion of the rudder. The pilot said that he had not properly inspected the landing zone, and that his airspeed was too fast on final approach. He also stated that the airplane did not experience any mechanical malfunctions prior to the accident.
Probable cause
The pilot's excessive braking during the landing roll, which resulted in the airplane nosing over onto its back. Contributing to the accident was the pilot's decision to land on a sandbar that he had not adequately inspected and his improper airspeed while on final approach.

- 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.
