Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that during the return flight to the airport, the glider did not have sufficient altitude to reach the airport, and he had to initiate an off airport landing. During the forced landing on rough terrain, the glider ground looped to the right and the landing gear collapsed. The glider sustained substantial damage to the landing gear attachment points and fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the glider that would have precluded normal operation.
