Analysis
The pilot of the amphibious float equipped airplane reported that while landing on the water, he experienced a very hard, violent landing with a nose down pitch attitude and the airplane nosed over. He further reported that, prior to the landing on the water he had previously departed a land based airport and while on final approach to the lake for landing, he was distracted by a boat in the area and did not verify that the landing gear was retracted for a water landing. The airplane sustained substantial damage to both wings and right-wing lift struts. The pilot also reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
