Accident Overview
A pilot was conducting a takeoff from a narrow river when the aircraft swerved left and collided with the riverbank. The pilot reported that he initially kept the water rudders extended for steerage during the downriver takeoff. He stated that when the airplane came up on step, it swerved left toward the shallow water, and he did not have time to avoid striking the riverbank.
Pilot Statement
The pilot indicated that the swerve was likely caused by a wind gust from the left or by the left float dragging on the shallow river bottom. He did not specify which factor was more probable.
Passenger Accounts
Five of the six passengers aboard provided written statements to the NTSB. Three of the five reported that the wind conditions were calm at the time of the accident. The remaining two passengers did not mention the wind conditions. All five passengers noted that the airplane veered to the left, towards the riverbank, when the pilot diverted his attention and lowered his head to retract the water rudders.
