## Analysis

The pilot of the amphibious light sport airplane reported that during a water landing, he did not configure the landing gear to a retracted position, and the airplane touched down in the water with the landing gear extended. Subsequently, the airplane nosed over and sustained substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation
