Analysis

The air taxi pilot was attempting to land his float-equipped airplane on a remote mountain lake in gusty wind conditions. He stated that he touched down with a tailwind component of approximately 5 knots, but that the tailwind increased rapidly during a gust, causing the airplane to decelerate much less quickly than he had anticipated. The airplane struck the beach with enough forward velocity to cause it to nose over.
