NTSB Factual Report

The pilot was taking off near a river bank in a float-equipped airplane. During takeoff initial climb the pilot was distracted by the water rudders, and looked inside the airplane. During that moment of inattention, the airplane turned toward the river bank, and impacted trees. There were no reported mechanical anomalies with the airplane prior to the accident.

NTSB Probable Cause
