NTSB Narrative Summary Released at Completion of Accident

The pilot landed the tailwheel-equipped airplane on a hard surface runway. The airplane was equipped with 29-inch tundra tires. During the landing roll, the left main landing gear wheel began to vibrate. The left wheel axle then broke, and the left wheel departed from the landing gear strut. The left wing tip struck the ground, and the airplane received damage to the left wing, left aileron, and the left elevator. The pilot stated the axle attaching bolts that secure the axle to the strut were stripped of their threads.

NTSB Probable Cause Narrative

A separation of the axle from the landing gear strut due to overload, and stripping of the axle bolt threads.
