What happened
A charter flight was transporting five passengers to a remote cabin when the pilot decided to land in a small harbor adjacent to an ocean channel due to large ocean swells present in the channel.
During the landing sequence, the aircraft encountered a tailwind as it reached the end of its runout, which extended the required water run. As the airplane traveled abeam a break in the shoreline at the entrance of the harbor, it was struck by an unexpected gust of wind originating from the right. This gust caused the aircraft to begin turning toward the right. Despite all attempts by the pilot to maintain control of the aircraft, the plane ultimately struck a beach area located at the north end of the harbor.
