- 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
- 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 noted that he was on approach to the runway and about 30' to 50' above ground when he encountered a wind shear downdraft so severe that all loose things in the cockpit flew up to the ceiling. He believed that he must have been crabbing at the time of touchdown, and the side forces at the time of the landing broke the right main landing gear above the wheel/axle casting. The airplane sustained buckling of the right wing and buckling at the rear of the cabin. Control tower personnel who observed the landing characterized it as a very hard landing. Visual meteorological conditions prevailed at the time of the accident, however winds were at 30 knots, gusting to 41 knots.
Probable cause
A hard landing due to the pilot's failure to maintain a proper descent rate. Factors include gusts and turbulence.

- 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. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1998-12-20.
