NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The pilot attempted to takeoff from a lake, with a 25 knot left crosswind. The first attempt was made close to shore, in the shelter of a bank on the lake's edge. The pilot told the NTSB investigator-in-charge (IIC) that the airplane's nose would not turn right, so he aborted the takeoff. He water taxied the airplane with the flaps set to the 1/2 position, farther downwind into the lake. He began to turn left, into the wind, and the wind lifted the left wing. The pilot said he added power, the right float dug into the water, and the airplane nosed over. The pilot indicated he was late, in a hurry, and should not have taxied in high winds with the flaps extended.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot's inadequate compensation for wind conditions during the downwind to upwind taxi turn. Factors associated with this accident were the high crosswind, the pilot's improper use of flaps, and his self-induced pressure because he was behind schedule. Full narrative available
