NTSB narrative
DURING THE LOCAL FLIGHT OF THE EXPERIMENTAL AIRPLANE, A CONNECTING ROD BROKE IN THE ENGINE. THE PILOT WAS ABLE TO MAKE IT BACK TO THE AIRPORT FOR A FORCED LANDING BUT WAS UNABLE TO LAND ON THE RUNWAY DUE TO ANOTHER AIRPLANE THAT TAXIED ONTO THE RUNWAY IN FRONT OF THE APPROACHING AIRPLANE. THE AIRPLANE MADE AN OFF-RUNWAY, HARD LANDING, AND BOTH LANDING GEARS COLLAPSED. THE PLT DID NOT FILE AN ACC REPORT.
Probable cause
TOTAL FAILURE OF THE ENGINE CONNECTING ROD.

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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1989-06-03.
- API snapshot SHA-256: 6dcf3c5cba26be3adca0b19440da18a440a8abb2bcd3a70947d3ba135d0e96f3; retrieved 2026-09-23T07:32:54.629Z.
