NTSB investigators used data provided by various sources and may not have traveled in support of this investigation to prepare this aircraft incident report.

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.

The National Transportation Safety Board determines the probable cause(s) of this incident to be:

Fatigue failure of the left main wheel assembly on takeoff, which resulted in a loss of directional control and runway excursion.
