The pilot reported that during takeoff from a remote site surrounded by trees, he encountered windshear and a gusting tailwind during the initial climb. He said that once the airplane climbed above tree level, the airplane stopped climbing, lost altitude, and then struck a stand of trees at the departure end of the site, resulting in substantial damage to the wings and empennage. The pilot reported that there were no pre-accident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The pilot was landing the ski-equipped airplane on a snow covered lake when the left ski encountered a snow drift, and the airplane nosed over, resulting in substantial damage to the left wing and vertical stabilizer. The pilot reported no preaccident mechanical anomalies with the airplane.
