Event Location
Probable Cause
The pilot's failure to maintain a positive climb rate during takeoff initial climb, resulting in an uncontrolled descent and collision with trees and terrain.
Full Narrative
The pilot of the float-equipped airplane stated that after takeoff from a lake, about 30-50 feet above the treetops, the airplane encountered a downdraft and descended uncontrolled into trees and terrain.
The nearest weather reporting station was 7 NM to the north, and reported that the wind was 350 degrees true at 17 knots, with gusts to 23. The airplane sustained substantial damage to the wings and the elevator.
The pilot reported that there were no mechanical failures or anomalies prior to or during the flight that would have prevented normal operation.
