NTSB narrative
According to the pilot, he took off from the airport in his amphibious experimental airplane with the intention of flying a closed traffic pattern. Because he planned to land back on the runway, he left the landing gear in the extended position. During departure, he overflew a river, located about 3 miles north of the airport, and observed that the water was calm. The pilot stated that he made a spur of the moment decision to land in the river, and he forgot that the wheels were extended. The airplane was not equipped with an aural gear warning horn or gear position lights; however, it was equipped with mirrors on each wing in which he could have visually determined the position of the gear. The pilot stated that he did not check the position of the gear with the mirrors. He indicated that he forgot to raise the gear prior to landing in the water. Consequently, the airplane nosed over as it decelerated. During this event, a portion of the lower engine cowl broke, and most of the front windscreen separated from the cockpit. The pilot reported that he did not experience any malfunction with the airplane.
Probable cause
The pilot's failure to raise the landing gear wheels prior to landing in water, resulting in a nose over.

- 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.
