NTSB narrative
While practicing step taxiing on the river the pilot under instruction attempted to transition from step taxi to plow taxi. During the transition the right wing dropped and contacted the water, which damaged the right sponson. The flight instructor added power and proceeded to takeoff. The airplane climbed to 10 feet above the water when it then started a slow uncontrollable turn to the right. The airplane lost altitude and impacted the water. Both pilots egressed the airplane unhurt. The airplane's hull/fuselage was substantially damaged and it took on water.
The pilot reported no preimpact mechanical malfunction or failure with the airplane that would have precluded normal operation.
Probable cause
The pilot's failure to maintain lateral control while taxiing. Contributing to the accident was the incorrect decision to takeoff once the sponson had been damaged.

- 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.
