Investigating agency: NTSB
Narrative:
A flight instructor and a commercial pilot receiving instruction departed from a pond (at an elevation of approximately 1,100 feet) in the float-equipped airplane. A camera recovered from the wreckage disclosed images indicating that the flight went to a mountain lake where a touch-and-go landing was made. The images indicated that the airplane accomplished this landing with an estimated 10-knot, gusting to 20-knot, headwind. After liftoff from the water, the airplane reversed course toward rising mountainous terrain. The wreckage was located at 5,200-feet, and the terrain in the immediate area of the accident site was level. The airplane came to rest on its nose, with the wreckage evididence indicating a stall/loss of control and vertical descent to the ground. The empennage remained nearly vertical to the terrain and bent down slightly. Both floats were also vertical to the terrain. Postaccident inspection of the airplane found no evidence of any preimpact mechanical discrepancies with the airframe or engine that would have prevented normal operation. The density altitude at the time was estimated as 6,907 feet.
Probable Cause: The pilot's failure to maintain airspeed while maneuvering, resulting in an aerodynamic stall and loss of aircraft control. Contributing to the accident were rising mountainous terrain and a high density altitude.
