NTSB narrative
The pilot reported that after a normal release about 2 miles north of the airport at 3,000 feet, he turned the glider south towards the airport. Approximately 1 mile from the airport the glider encountered strong winds from the south and it entered a high rate of descent with minimal forward motion. The pilot determined the glider would not make the airport and he executed an off-airport landing. During the landing, the right wing struck a bush and the glider ground-looped, substantially damaging its wings and fuselage. The pilot reported no mechanical failures or malfunctions with the airframe prior to the accident. An airport located about 9 miles to the east of the accident airport indicated at the time of the accident wind was from 180 degrees at 11 knots, gusting to 16 knots.
Probable cause
The pilot’s inability to make it to the airport as a result of his inadequate planning for the gusting headwinds.

- 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.
