Analysis

After liftoff from a lake the airplane's engine stopped producing power and the airplane began settling toward the remaining lake. The engine surged and the airplane crashed on the tundra, 200 yards from the lake's edge. The pilot stated that he drained the fuel sumps on the first flight of the day and found water, but did not drain the fuel sumps on subsequent flights.
