NTSB narrative
The pilot stated that he made a normal approach to the runway, had a normal touchdown, and the aircraft bounced once during the landing rollout. Approximately 15 to 20 yards into the landing rollout the left axle broke, causing the left gear leg to penetrate into the turf runway. The left wing contacted the ground, aircraft nosed over, and then came to a stop in an inverted position. Pilot stated that he shut down all of the aircraft systems and evacuated the passengers from the aircraft. Post accident investigation showed no indications of a hard landing or significant side-loading applied to the landing gear. The aircraft had been converted into a conventional gear type aircraft under a Supplemental Type Certificate (STC) in June of 1995. Subsequent investigation done by an inspector with the Federal Aviation Administration (FAA) showed that the STC requires that there is an installation of wheel spindles inside the axle assemblies to provide reinforcement. On site investigation, completed by the FAA, indicated that the above noted spindle assemblies were not present at the time of the accident.
Probable cause
The aircraft modification not being in compliance with the Supplemental Type Certificate. A factor to the accident was the fracture of the landing gear axle during landing.

- 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 1998-06-10.
