Analysis

The pilot reported that he was landing the airplane on the water and that after he conducted his before landing “GUMP” checklist he extended the landing gear on his amphibious airplane in error.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
