Analysis
The pilot of the float-equipped airplane reported that, during landing, the touchdown on the water was smooth. While the airplane was on step, she reduced the flaps, and the airplane suddenly veered left. She applied right rudder and reduced engine power. The left float hit the concrete shore bank, the airplane spun to the left, and the right wing struck the shore.
The airplane sustained substantial damage to the fuselage and both wings.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain directional control during landing.
