What happened
Approximately 90 minutes after off-loading passengers and cargo, the pilot of an amphibious airplane returned to a gravel beach site. After landing on an adjacent lake, the pilot taxied up an inclined shoreline onto the beach, heading toward a campsite where the previous group of passengers had established themselves.
While taxiing across the beach, the pilot attempted a left-hand 180-degree turn to reposition the aircraft to face the lake. During this maneuver, the tail of the aircraft struck one bystander and narrowly missed a second individual. The pilot reported seeing several people on the beach at the time but did not observe the person who was struck by the aircraft.
