Narrative:
The tail wheel equipped airplane sustained substantial damage when it ground looped during a high speed taxi. The instructor stated, "The aircraft started to go right, and I assisted the student in straightening it by applying a small amount of left brake. Then the aircraft started to swerve violently to the left, and I applied full right brake, which didn't stop the motion but may have kept the wing from hitting the ground. We made approximately a half circle, turning about 135 [degrees], managing to stay on the runway the whole time. ... We were using Runway 30 with a light east wind." The instructor reported no mechanical malfunctions prior to the accident and stated that the aircraft sustained damage to the airframe tubing during the accident.

Probable Cause: The instructor pilot's inadequate remedial action to the dual student's loss of aircraft control during high speed taxiing which lead to the inadvertent ground loop/swerve. A factor was the student not maintaining aircraft control.
