Analysis

While attempting to perform a precautionary landing on a beach following a partial loss of eng power during cruise flt, the non FAA certificated plt inadvertently stalled the airplane which descended uncontrolled & collided with the water in a nose & rt wing low attitude. He further stated that he believes that the loss of power was due to overheating of the eng. It was not examined therefore no determination could be made as to the reason for the partial loss of power. The airplane was not registered with the FAA but was required to be.
