- Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
- Part 91: General Aviation
- Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
- Maneuvering
- First occurrenceThe 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
- Loss of control in flight
- Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary
- Stall
- 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 glider was towed by an airplane to an altitude of 11,800 feet mean sea level (msl) approximately 7 miles south of the departure airport. The glider was released from the tow airplane, and the tow airplane returned to the airport to tow another glider to join the accident glider. Approximately 15 minutes later when the tow airplane returned with the other glider, the tow airplane and other glider attempted to contact the accident glider via radio. The attempts to contact the accident glider were unsuccessful. The glider was located in mountainous tree-covered terrain the next day. The weather at the time of the accident was reported as clear sky and light winds. Examination of the glider wreckage revealed the damage was consistent with a nose-low, vertical impact. No anomalies were noted with glider that would have precluded normal operations.
Probable cause
The pilot's failure to maintain aircraft control while maneuvering resulting in an inadvertent stall and impact with terrain.

- 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, coordinates. 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.
