NTSB narrative
The glider landed in a filed north of the runway about 2,000 feet short of the intended touchdown point. According to the Certified flight instructor (CFI), pilot-in-command, the aircraft entered a left base for runway 21, and turned final about 3-4,000 feet from the runway, at an altitude of about 800 agl. He instructed the student pilot to deploy the spoilers in order to get down to glideslope, and maintained pattern speed of 50 knots. The CFI took control of the glider. He said the glider started to sink fast, and the airspeed was 43 knots. The spoilers were closed, but the CFI said, '...we were too low to make the runway...I made a descending right turn while deploying the spoilers and slowing...the only option was a small pasture less then 300 feet long with...trees at the far end and a ditch...I stalled at about 2-3 feet above the ground with the right wing slightly down, still turning. The plane pivoted around the right wing tip and stopped in about 60 feet.'
Probable cause
the pilot-in command's improper handling and inflight decisions resulting in an undershoot of the intended landing runway. The pilot-in-command then failed to maintain airspeed, which resulted in a stall and the right wingtip impacting the ground.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
