| Confidence Rating: |  Accident investigation report completed and information captured |
The non-floatplane rated private pilot-in-command (front seat), accompanied by an ATP rated flight instructor (rear seat), was step taxiing in preparation for takeoff on the Willamette River. During the step taxi the aircraft's right float impacted an unmarked, submerged log protruding about 15 inches above the water's surface. The right float was breached and the aircraft gradually nosed over and sank.
Probable Cause: The front seat (pilot-in-command's) inadequate visual lookout during step taxi resulting in the aircraft's collision with a partially submerged log. A contributing factor was the log and it's lack of any conspicuous marking.
