NTSB narrative
The pilot reported that before the accident, he landed without incident and taxied back for takeoff. During the subsequent takeoff roll, he felt a "jolt" and heard a "thumping" sound from the left main wheel. The airplane immediately veered to the left and departed the runway pavement. A postincident examination revealed that a section of the outboard half of the left main wheel assembly had failed. Airplane damage was limited to the left main landing gear, engine cowling, and propeller assembly. Metallurgical examination of the left outboard wheel revealed that it failed as a result of fatigue.
Probable cause
Fatigue failure of the left main wheel assembly on takeoff, which resulted in a loss of directional control and runway excursion.

Source notes (4)
- 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, coordinates. 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.
