The NTSB's narrative final · quoted from the NTSB record
The flight instructor of the tailwheel-equipped airplane reported that, while demonstrating a wheel landing during an instructional flight with a student in the rear seat, the nose swerved to the right upon lowering the tailwheel. The pilot corrected with left rudder input, but the airplane ground looped to the right, resulting in substantial damage to the left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
