NTSB narrative
The pilot of a twin-engine, turbine-powered airplane was landing at a remote, rough, soft, turf and grass covered airstrip at the completion of a Part 135 cargo flight. He said that after an uneventful touchdown, as the airplane’s landing roll slowed, the right main landing gear wheel and the nose wheel contacted an area of soft, muddy terrain. The airplane’s nose wheel collapsed, and it subsequently folded under the fuselage. The airplane sustained substantial damage to the fuselage. The pilot reported no mechanical problems that would have precluded normal operations.
Probable cause
The pilot’s selection of an unsuitable landing site, which resulted in the nosewheel collapsing.

- 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 2022-06-08.
