Factual narrative

According to the pilot, he inadvertently did not retract the wheels of the amphibious airplane after takeoff from a hard surface runway. Upon arrival at his destination, he did not use the before landing checklist and when the airplane touched down on the water with the wheels extended, it nosed over. The amphibious airplane sustained substantial damage to the right wing lift strut, the empennage, the right wing aileron, the rudder, and the elevator. The pilot asserted that the accident was pilot error and that the accident could have been prevented had he used the checklist. The pilot reported that there were no mechanical malfunctions or failures with the amphibian airplane that would have precluded normal operation.
