Due to a lack of thermals the glider pilot was forced to make an outfield landing.
The landing went as planned. The pilot expected to land in a freshly cut field, which turned out to be Barley. A
The left wing, which was the slightly uphill side of the slope, caught the wheat first. The glider ground-looped.

The glider sustained structural damage to its tail boom, lower left wing and aileron (which required major repairs). No person was injured.

Probable Cause(s)
The glider could not sustain flight due to the absence of thermals which resulted in loss of height.
The pilot conducted a field landing, and during the landing process, the left wing was caught by
vegetation and the glider ground looped. The glider sustained substantial structural damage.
