Narrative:
After two unsuccessful power-off landing attempts at a short field, the certificated flight instructor (CFI) took control of the tail wheel airplane to demonstrate the proper technique. On short final, the CFI told the pilot to, 'guard the controls,' who then placed his hands and feet near the controls. The CFI stated that he wanted the other pilot to correct any erroneous inputs during the landing. The airplane drifted right on touchdown, and the CFI responded with left rudder. The CFI reported that the rudder would move only about 1 inch, when it suddenly 'let go,' and full left rudder was applied. The airplane immediately went left, and with little remaining runway, the CFI kicked 'full right rudder to intentionally ground loop the airplane.' The pilot stated that he did not feel the binding. The CFI had a total of 36 hours in make and model, none in the last 90 days. Removal of the floor panels and a examination of the rudder cables verified proper installation, and no 'witness marks' of binding controls were found.

Probable Cause: The flight instructor's failure to maintain control of the airplane which resulted in his intentional ground loop. A factor in the accident was the flight instructor's lack of currency in tailwheel airplanes.
