- From Salt Lake City International Airport (SLC), Salt Lake City, UTTo Bolinder Field Tooele Valley Airport (TVY), Tooele, UT
- Aircraft age
- About 9 years (built 2008)
- 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
- Approach · VFR go-around
- 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 solo student pilot reported that, during landing, the airplane "ballooned up and [he] added a little throttle [to] settle the [airplane]." He added that "the [airplane] seemed to settle but felt like it was coming down too fast." He applied full power to go around and reduced the flaps to 20°. He added that "the [airplane] was stalling and so [he] moved the flaps to 0 degrees, which caused the plane to continue to stall." Subsequently, the airplane impacted the ground.
The airplane sustained substantial damage to the wings and empennage.
The student pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The student pilot’s failure to maintain adequate airspeed and his exceedance of the airplane’s critical angle of attack during an attempted go-around, 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: 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.
- API snapshot SHA-256: 978d2b5b8d831bf91efbf061ce9a46264923eade47495f06d0fe642f133cbfe3; retrieved 2026-09-16T05:22:29.188Z.
