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 stated that the glider was at 2,500 feet as he searched for lift and a suitable off-airport landing site simultaneously. Shortly thereafter, the glider lost lift, and the pilot landed in a soybean field. During the landing, the glider touched down 1/4 mile short of the planned touchdown point and ground looped, which resulted in substantial damage to the left wing. The pilot did not report any preimpact mechanical anomalies that would have precluded normal operation.

Factual narrative

The pilot stated that the glider was at 2,500 feet as he neared the completion of the second leg of his three-leg cross-country flight. He searched for lift and a suitable off-airport landing site simultaneously, in case he was unable to find lift. The glider encountered sink, and the pilot completed a landing to a soybean field. The glider touched down one-quarter mile prior to the point of intended landing and ground-looped, which resulted in substantial damage to the left wing. The pilot did not report any pre-impact mechanical anomalies that would have precluded normal operation.
