NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

The amphibious float equipped airplane was substantially damaged while landing on a lake. Witnesses reported that the airplane attempted to land on the lake with the wheels down. One witness described the approach as "level and very routine." Attempts to rescue the pilot after the accident were not successful. The post accident examination revealed that all 4 wheels were in the down and locked position. The landing gear selector handle was in the up position consistent with a water landing. The gear selector circuit breaker was in the open position. The gear pump and gear advisory circuit breakers were in the closed position. Each main gear assembly was equipped with a mechanical gear position indicator. The left and right main gear indicators were visible from the pilot and front passenger seats, respectively. The mechanical gear position indicators were intact. Electrical continuity of the gear position switches, gear selector, and gear position indicator lights was confirmed. The gear retraction and extension hydraulic cylinders and linkages appeared undamaged. The main and nose gear assemblies were intact. The hydraulic gear pump operated in both directions when tested after the accident.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's inadvertent attempt to land on water with the wheels down and his failure to verify the gear position prior to landing. Contributing factors were the inoperative gear system due to the open gear selector circuit breaker, which tripped for undetermined reasons.
