Summary
On April 07, 2017, a Stinson 108 (N9363K) was involved in an incident near Woodruff, WI. All 2 people aboard were uninjured. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this incident to be: The pilot receiving instruction's incorrect brake usage and failure to maintain directional control during the landing roll.
The flight instructor of the tailwheel-equipped airplane reported that during a 3-point landing touchdown, the airplane pulled to the left and he heard a "pop." He added that the pilot who was flying and receiving instruction "locked up" the right brake. Subsequently, the airplane departed the runway surface to the right, and ground looped.
During an interview with a Federal Aviation Administration Aviation Safety Inspector, the pilot receiving flight instruction reported that during the landing roll, the airplane drifted to the left and he applied right brake to correct. He added that upon braking, he heard the left tire blow and the airplane departed the runway to the right.
