The 8-hour student pilot lost control of the tricycle gear single-engine airplane during the takeoff roll on his first solo flight. Witnesses at the airport reported that prior to his first solo flight, the student pilot and his flight instructor had completed 7 touch and go landings without incident. The flight instructor dismounted the 2004 model airplane and endorsed the student pilot's logbook for his first supervised solo flight. While on the takeoff roll from runway 17, the airplane was observed drifting off the east side of the runway onto the grass for about 600 to 800 feet. When the airplane crossed taxiway Alpha 4, the nose landing gear collapsed upon impact with the lip of taxiway Alpha 4. Runway 17 was described as a 5,999-foot long, by 150-foot wide, asphalt runway, which was reported to be dry at the time of the mishap. An FAA inspector, who traveled to the accident site, reported that there was no evidence of braking being applied on the runway surface. He added that no anomalies were found with the aircraft nose wheel steering nor the braking system of the airplane. The instructional flight originated from another airport located 23 nautical miles southeast of the mishap airport. The weather at the airport at the time of the mishap was reported as clear skies with winds from 120 degrees at 4 knots.
