Aircraft involved

Probable cause & findings

The pilot's failure to extend the landing gear for a runway landing, which resulted in a gear-up landing.

Factual narrative

The pilot reported that he failed to extend the landing gear on the amphibious airplane for a landing to an asphalt runway. Subsequently, the airplane landed with the landing gear in the retracted position, which resulted in substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
