NTSB narrative
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.
Probable cause
The pilot's inability to maintain aircraft control due to the failure of the left main landing gear wheel, which resulted in the separation of the wheel from the aircraft.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
