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, just prior to touchdown while landing on a lake in gusting wind conditions, he attempted to execute a go-around. The float-equipped airplane inadvertently contacted the water and bounced twice on the surface. The pilot lost directional control and nosed over which resulted in substantial damage to the right wing and vertical stabilizer. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
