NTSB Factual Report

The pilot stated that shortly after takeoff in variable wind conditions from a float pond in his float-equipped airplane, the wind shifted, and the airplane began a descent that he was unable to stop. The airplane had passed the shoreline, and descended onto the ground, where it nosed over and sustained substantial damage to the wings and fuselage. He said there were no mechanical problems with the airplane prior to the accident, and that he should have waited for a more favorable wind.

NTSB Probable Cause

The pilot's decision to take off in a variable wind, resulting in a shallow climb and collision with terrain.
