## Analysis

The pilot stated that he was attempting a takeoff from a lake in choppy water and with gusting wind when the left wing of the airplane contacted the water after liftoff. The airplane then impacted in a nose-down attitude resulting in substantial damage to the left wing and separation of both floats. No preexisting mechanical anomalies were found with the airplane.
