NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The private pilot was taking off in the float plane from the lake's west waterway. The airplane was on step, gaining airspeed, and the takeoff run seemed normal to the pilot. The airplane was nearing takeoff speed, and proceeding directly down the waterway, when it encountered a right quartering tailwind gust that lifted up the right wing and float. The airplane veered to the left toward a steep bank, and the pilot was unable to correct the deviation with the rudder. He did not feel that he could reduce power as he would slam into the bank. The airplane lifted off, but the float collided with the top of the bank. The airplane cartwheeled about 160 degrees to the left before coming to rest on its right side. It sustained substantial damage to the wings, fuselage, and floats. The pilot reported that there were no mechanical malfunctions or failures. Reported wind at the airport approximately 3 minutes after the accident was from 020 degrees magnetic at 3 knots, with no recorded gusts.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot’s failure to maintain directional control during takeoff.
