The wind was variable and shifting from onshore to offshore. After the run-up, the pilot taxied to the hold short line and noted that the wind continued to shift. Immediately after clearing the pilot for takeoff on runway 10R, the controller told the pilot that the winds had shifted and now were from 330 degrees at 6 knots. The pilot noted that she would be taking off with a left quartering tailwind. During the ground roll, she pushed the stick forward to bring the tail up, then she eased up on the forward pressure and the airplane became airborne momentarily. The pilot was attempting to get the airplane into ground effect for more airspeed, but the wind changed direction again and the airplane yawed to the left. She tried to correct, but stated that there was no lift and no altitude, and the airplane was in a nose-up attitude. The nose quickly dropped to the right, and the airplane came to a rest on its belly off to the right side of the runway. The tail wheel and left gear collapsed, the left wing tip was damaged, and the prop struck the ground. The pilot said that there were no preimpact mechanical malfunctions or failures with the airplane.
