NTSB narrative
The commercial pilot attempted to takeoff downstream on a 14 CFR Part 91 business flight in a float equipped airplane. He stated that as he reached his predetermined point to abort the takeoff if not airborne, he continued the takeoff run because he felt the airplane would liftoff soon. The airplane did not become airborne, and while attempting to negotiate a sharp turn in the river while on-step, the airplane collided with alders and the left riverbank, sustaining structural damage to the wings, fuselage, and floats.
Probable cause
The pilot's selection of unsuitable terrain for takeoff, which resulted in a loss of control during the takeoff roll, and an encounter with high vegetation and a river bank. Factors associated with the accident are high vegetation and a riverbank.

- 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, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2005-08-23.
