## Analysis

The pilot in the amphibious airplane reported that, he was going to land on the runway. During the approach he slowed too much, and the airplane bounced during the landing. The pilot elected to go around but retracted the landing gear before applying power. The airplane subsequently settled to the runway with the landing gear retracted. The keel of the amphibious airplane was substantially damaged. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
