On August 31, 1997, about 1318 eastern daylight time, a Cessna 172M, N9625V, collided with the runway during the landing portion of a touch and go landing at the Gwinnett County Airport, Lawrenceville, Georgia. The airplane was operated by The Flight School under the provisions of Title 14 Part 91, and visual flight rules. Visual meteorological conditions prevailed. A flight plan was not filed for the solo instructional flight. The student pilot was not injured, and the airplane was substantially damaged. The flight originated from the same airport abut 1300, on the same day. According to the pilot, he departed the airport for the practice area, and returned for touch and go landings. During the first attempted touch and go landing, the pilot stated he flared early, recognized he would land hard, and added power. The nose pitched up and the airplane stalled. The pilot stated he held the stall for about 25 to 40 feet, hoping to do a go-around. The airplane then yawed left and the left wing dropped, impacting the runway. The airplane then skidded off the runway. According to the pilot, the outboard 1/4 to 1/3 of the left wing was bent upward.
