NTSB narrative
The single-engine float plane was unable to maintain a climb after takeoff from a canal. The commercial pilot reported that after climbing to about 200 feet, he "felt like the aircraft was slowly losing power...and was starting to descend." The only available landing area was a canal that was located 90 degrees off the left side of the airplane. The pilot elected to turn left, and estimated that while in a 30-degree angle of bank the airplane “stalled.” The pilot was able to get the wings level prior to touchdown. The airplane impacted the water in a nose-down attitude and immediately nosed over and came to rest in an inverted position. The float landing gear separated from the fuselage during the impact and the airplane subsequently sank. The pilot and his passenger received minor injuries. The reason for the reported loss of power was not determined.
Probable cause
The pilot's failure to maintain adequate airspeed in a turn while attempting to return to land, which resulted in an aerodynamic stall. Contributing to the accident was the reported loss of engine power for undetermined reasons.

- 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.
