Upon arrival at the destination airport, the pilot hovered the helicopter about 2 feet above the ground and prepared to land. The pilot noted that during the hover while the nose of the helicopter was pointed east, the wind shifted direction and gusted from the west. The helicopter's tail section raised and the nose lowered, which allowed the main rotor blades to strike the ground. The helicopter rolled over on its left side and sustained substantial damage to the main rotor blades and fuselage. The Federal Aviation Administration inspector responded to the scene; an examination of the helicopter was conducted and did not reveal any evidence of mechanical malfunctions or failures that would have precluded normal operation. The pilot noted that if he had kept the helicopter's nose pointed into the wind then the accident might not have occurred.
