Analysis
The pilot was performing a high speed taxi before an intended local flight. During the high speed taxi, the airplane's tail rose off the ground, and the pilot reduced power. During the subsequent rollout, the tailwheel started to shimmy, and the pilot applied left and right rudder. The airplane veered left, exited the runway, went down a steep slope, and impacted the side of a drainage ditch, which resulted in substantial damage to the wings and fuselage. The pilot reported no mechanical malfunctions.
