Analysis

According to the pilot he was landing on the lake with one notch of flaps indicating 50-55 mph. The touchdown was smooth and after planing for 3-4 seconds the acft veered left. He corrected to the right and the acft straightened then suddenly veered right, submerging the right float tip and inverting the acft.
