Analysis narrative
The pilot of the tailwheel equipped airplane reported that, during an instructional flight practicing landings to a full stop, the airplane veered left, directional control was lost and the left wing and left elevator were substantially damaged when they contacted the runway surface during a ground loop. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
