NTSB narrative
A powered airplane was towing the glider. During the takeoff roll, the glider lifted off the ground and began to rise too high. The pilot overcorrected the glider and it struck the ground. 'Pilot induced oscillations' ensued, and the pilot could not control them. The pilot released the towrope, and the glider 'cartwheeled' on the ground before coming to rest inverted. The pilot reported 250 hours of total experience in gliders, with no experience in make and model.
Probable cause
The pilot's failure to maintain control of the glider. A factor related to the accident was the pilot's lack of experience in make and model.

Source notes (4)
- 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.
- API snapshot SHA-256: ee7a15c16cb390426d2af14816004adb86ab1c756c79042b857db55be1ac3778; retrieved 2026-09-21T20:14:13.031Z.
