Probable cause

The pilot's failure to keep the aircraft on the step and he allowed it to become airborne. The pilot subsequently lost depth perception, and his failure to maintain proper rate of descent, resulting in a hard landing and collapse of the float landing gear. A factor relating to the accident was the glassy water condition of the landing surface.
