Analysis

The pilot reported that his 3-point touchdown in the tailwheel equipped airplane was normal, but during the ground roll the airplane started to veer to the right. He attempted to correct with the left rudder, but the airplane departed the runway to the right and impacted a ditch. The pilot reported that his pant leg may have gotten caught on the right heel brake. The fuselage and firewall sustained substantial damage. The pilot stated that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
