Analysis

The pilot reported that, he was conducting a touch-and-go in his float equipped airplane on a pond directly to the south of a private runway. After he completed the touch-and-go, and during the initial climb, he altered his course to the right for traffic departing from the nearby runway and impacted a tree. He attempted to return to the pond but was unable and subsequently impacted trees and a powerline, which resulted in substantial damage to the wings and fuselage. The pilot reported no preaccident mechanical failures or malfunctions that would have precluded normal operations.
