Probable cause

The certified flight instructor's inadequate compensation for the crosswind and delayed remedial action during landing, which resulted in a ground loop.

NTSB narrative

The certified flight instructor (CFI) stated that he was providing instruction to a student pilot in a glider. After a routine local instructional flight, they returned to the departure airport for landing. The student was flying the glider and the CFI was providing verbal instructions to him as they completed a standard traffic pattern to the dirt landing area. He reported that there was a crosswind at 12 knots, gusting to about 20 knots. The glider encountered a high sink rate and the CFI took authority over the controls. The glider ground looped, resulting in substantial damage to the tail. The CFI reported no preimpact mechanical malfunctions or failures with the glider that would have precluded normal operation.
