Analysis

The amphibian airplane sustained substantial damage during takeoff when its float encountered a wave. The pilot stated, "As airspeed increased, the aircraft encountered slightly larger waves and as airspeed approached rotation speed, began hitting the crests of the waves. Just before rotation, a snap was heard and takeoff was immediately aborted. As the aircraft quickly decelerated, the front pilot side float strut pierced through the fuselage by pilot rudder pedals and the whole float assembly collapsed."
