Probable cause

Analysis

The lodge employee pilot reported that he took off from a small lake toward rising terrain that he could not outclimb. The pilot reported that he tried to turn around below the level and clipped a tree with his wing tip and the spreader bars on the floats. Aircraft impacted in marshy area near the lake. The pilot said that he believed he misjudged the takeoff and possibly accepted a tailwind component.
