NTSB narrative
The pilot reported he was attempting to take off downriver in his float-equipped airplane. The airplane became airborne, but the pilot said it would not accelerate. He looked inside the cockpit at the engine and rpm gauges, and all were normal. When he looked outside, the airspeed had decayed, and the airplane settled onto the river. The pilot turned the airplane to miss a gravel bar, but struck a tree with the right wing. The airplane turned to the right and collided with the river bank. Postaccident inspection of the airplane's engine disclosed no evidence of any preimpact mechanical anomaly.
Probable cause
The pilot's selection of an unsuitable area for takeoff.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1997-06-29.
- API snapshot SHA-256: f1b77b5e4178dad89c40b08682b1c06b88577cb033beb6b5e8e93dccd1ae1abd; retrieved 2026-09-22T19:20:13.518Z.
