NTSB narrative
The certified flight instructor (CFI) stated that the purpose of the flight was to practice glassy water landings in the float-equipped airplane. They overflew the practice area to check the condition of the river and the CFI stated that there were no obstacles or debris visible. Shortly after touchdown, both pilots reported hearing a loud bang and the airplane immediately nosed over. Both pilots exited the submerged airplane and sustained minor injuries. According to a Federal Aviation Administration inspector, the wreckage showed damage consistent with striking a submerged object. The airplane incurred substantial damage to its canopy, hull, and tail.
Probable cause
The airplane’s collision with a submerged object during landing, which resulted 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.
