NTSB narrative
The pilot stated that he and the co-pilot had just begun to taxi to the runway from their hangar. The airplane traveled about 150 ft when the ground gave way (sink hole due to a broken water main) under the left main landing gear. The landing gear collapsed, which resulted in substantial damage to the left-wing spar and lower fuselage. The left engine propeller blades were also damaged.
Probable cause
The airplane encountered a sink hole while taxiing.

- 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, coordinates, cause areas. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2024-03-04.
