- 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 pattern base
- 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/spin
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
- Destroyed
Cause areas
- Pilot in command › Airspeed, inadequate
- Pilot in command › Stall/spin, inadvertent

NTSB narrative
THE PRIVATE PLT AND PAYING PAX DEPARTED ARPT DURING AIR SHOW FOR LOCAL SIGHTSEEING FLT. MONIES RAISED FROM AIRPLANE RIDES AND AIR SHOW WERE TO BENEFIT LOCAL COMMUNITY HOSPITAL. SHORTLY AFTER ACFT DEPARTED RWY 21, WITNESSES SAID STRONG GUSTY WINDS DEVELOPED AS THUNDERSTORM APPROACHED. VIRGA WAS SEEN FALLING FROM ONE CELL, LOCATED ABOUT 3 MILES SOUTH OF ARPT. THE ACFT WAS NEXT SEEN ON WHAT WAS DESCRIBED AS A RIGHT X-WIND LEG FOR RWY 3 AT LOW SPEED. THE ACFT WAS THEN OBSERVED TO SPIN AND IMPACT THE GROUND. THE ACFT EXPLODED AND BURNED. PLT COULD NOT RECALL ANY DETAILS OF ACCIDENT.
Probable cause
THE INADVERTENT STALL-SPIN AT AN ALTITUDE INSUFFICIENT TO EFFECT A SAFE RECOVERY. CONTRIBUTING FACTORS INCLUDE HIGH DENSITY ALTITUDE AND WIND SHEAR.

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: a1b4d3de54d3a5cb4803cc2bd74e29990fdc3481b38a6c424b7f3936d422d7d2; retrieved 2026-09-21T03:18:01.642Z.
