Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that he was attempting to takeoff in the float-equipped airplane from a trailer pulled down the runway by a truck. He reported that there was a direct crosswind from the right at 7 knots. As the truck’s speed increased, the airplane shifted on the trailer and the left float contacted a vertical post that blocked the float from contacting the tire. As the airplane attempted to depart the trailer, the float chine caught on the trailer and turned the airplane toward the ground. The left wing struck the ground first, followed by the floats, propeller, and right wing. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
