- 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
- Landing
- 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
- Hard landing
- 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 pilot reported that he was cleared to 4,000 feet msl at his request. Approximately 40 miles southwest of Johnson County Executive Airport, Olathe, Kansas, the pilot noticed clear ice forming on the windshield and the wing's leading edge. He added that the rime ice build up was three inches thick. The pilot stated that he flew the localizer 36 approach at 120 mph and as he crossed the threshold of runway 36, approximately 20 feet above the runway surface, he started to 'round out and the airplane immediately stalled and hit hard'. The aircraft came to rest on the right side approach end of runway 36 where the right main and nose landing gear were found collapsed. At 1553, the Johnson County Executive Airport automated surface observing system recorded a surface temperature of -2 degrees Celsius and an overcast cloud layer at 2,200 feet msl. Advisory circular 00-6A, Aviation weather states, '...all clouds at subfreezing temperatures have icing potential. However, drop size, drop distribution, and aerodynamic effects of the aircraft influence ice formation.' AC 00-6A also states, '...If your aircraft is not equipped with deicing or anti-icing equipment, avoid areas of icing. Water (clouds or precipitation) must be visible and outside air temperature must be near zero degrees Celsius or colder for structural ice to form.' Post accident examination of the aircraft revealed 3/4-inch thick rime ice on the aircraft's wing and empennage leading edges.
Probable cause
The pilot's continued flight into adverse weather that resulted in structural icing and subsequently an aerodynamic stall on landing flare. A factor was the pilot's inadequate weather evaluation .

- 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.
