The student pilot was conducting his first solo flight. During the rollout after his third landing, the aircraft began to pull to the left. The pilot attempted to maintain directional control but the left main gear separated, causing the aircraft to nose over onto its back. The left main wheel and brake caliper were located several hundred feet behind the aircraft, along the rollout path. A mechanic who inspected the aircraft after the accident reported that the inner wheel half was broken around the brake disc mounting flange. The mechanic stated that there was no bluing from excessive heat or any signs that the bearings had failed.
