What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
During landing in a lake, the pilot misjudged the height of waves in choppy water caused by boats in the area. The aircraft hit the top of a wave and bounced, but did not have power to go around. The second touch down hit hard on top of another wave, causing a piece of trim to detach from lower part of the hull. The aircraft began to take on water, at which point the aircraft was moved to shallow water at the edge of the lake.
