Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that he was conducting a local flight to gain familiarity with the amphibious airplane's recently installed avionics. During a runway change at his home (land) airport, the pilot elected to conduct a water landing to a lake about 12 miles north, during which he inadvertently extended the landing gear on approach and landed on the water with the wheels extended. The airplane immediately nosed over and came to rest inverted in the water, substantially damaging both wings. The pilot did not report any preimpact mechanical malfunctions or failures that would have precluded normal operation.
