- Defining eventThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- Aerodynamic stall/spin
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative
The pilot reported that he turned from the base leg to final approach at about 400 feet with full flaps and spoilers extended. On final approach about 100 feet above the ground, he decided to change the flap setting from 20 degrees to 10 degrees as there was a crosswind. He said that as he tried to move the flap handle, the handle slipped from his hand and instantly changed the flaps to 10 degrees, which resulted in the glider losing lift and nosed down. He pulled back on the controls, but the glider stalled and collided with the ground resulting in substantial damage. The pilot reported no preimpact mechanical malfunctions or failures with the airframe or the engine that would have precluded normal operation.
Probable cause
The pilot's incorrect use of the flap control pitch control recovery which resulted in an aerodynamic stall.

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: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2011-07-16.
