## Analysis

AFTER TOUCHDOWN ON THE BEACH, THE AIRCRAFT STRUCK A THREE-WHEELED SCOOTER (ATV). THE ATV WAS SUBSTANTIALLY DAMAGED AND THE DRIVER OF THE ATV, AN ELEVEN YEAR OLD BOY, DIED A FEW DAYS LATER. THE ATV PASSENGER, A EIGHT YEAR OLD GIRL, RECEIVED MINOR INJURIES. WITNESSES NEAR THE ACCIDENT SITE STATED THAT AFTER THE AIRCRAFT TOUCHED DOWN, AND DURING THE LANDING ROLL, THE ATV CROSSED DIRECTLY IN FRONT OF THE AIRCRAFT AND WAS STRUCK BY THE PROPELLER. THE LANDING SITE SELECTED BY THE PILOT WAS A POPULAR BEACH, NORMALLY OCCUPIED BY LOCAL RESIDENTS OF A NEARBY COMMUNITY. HOWEVER, THE PILOT STATED THAT HE HAD SELECTED THE BEACH FOR LANDING SO HE AND THE PAX COULD LOOK AT LOCAL FISHING SITES.
