NTSB Factual Report

The pilot reported that during the third landing of the day in the tailwheel equipped airplane, the wind switched to a quartering tailwind. After touchdown the airplane began to veer to the right. Despite pilot control inputs, the airplane continued to the right and departed the runway surface onto the dirt. The airplane nosed over and came to rest inverted; its left wing and rudder sustained substantial damage. The pilot reported no mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

NTSB Probable Cause

The pilot's failure to maintain directional control during the landing roll with a tailwind.
