NTSB Narrative Summary Released at Completion of Accident

On the landing rollout the airplane ground looped. The certified flight instructor (CFI) reported that he was demonstrating a forward slip to lose altitude for landing. As the airplane was rolling out, he attempted to slow down by adding light pressure on both heel brakes. The airplane began a right turn, and he counteracted with additional pressure on the left brake, but there was no response. The airplane swerved off the runway and ground looped. A Federal Aviation Administration inspector examined the airplane's brake system. When he depressed the brakes he found them a little spongy but completely operational.

NTSB Probable Cause Narrative

the flight instructor's failure to maintain directional control during the landing rollout.
