On April 28, 1996, at 1744 hours mountain standard time, a Cessna 152, N6596P, owned and operated by Sawyer Aviation, Phoenix, Arizona, nosed over during landing rollout at the Chandler Municipal Airport, Chandler, Arizona. Visual meteorological conditions prevailed at the time of the solo instructional flight, and no flight plan was filed. The airplane was substantially damaged, and the student pilot was not injured. According to the pilot and Sawyer's chief flight instructor, the accident occurred during a round robin flight which originated from Phoenix around 1700. The purpose of the flight was, in part, to give the student pilot practice in solo flight takeoffs and landings. Nearing completion of the planned 1.3-hour-long flight, the pilot commenced his ninth touch-and-go landing. The pilot reported that the airplane bounced on runway 04R and he lost directional control. The airplane veered off the left side of the runway, collided with several lights, entered a dirt area and nosed over. At 1756, Chandler's wind speed was reported at 3 knots. The pilot's 17.2 hours of total airplane flying experience and 3.2 total hours of solo experience had been obtained during the preceding 90-day period.
