NTSB narrative
According to the pilot, during final approach he completed the landing checklist and confirmed that the green down and locked gear light was illuminated. On touchdown the airplane dropped onto its belly and slid about 200 feet before coming to rest on the runway. A postaccident examination of the airplane revealed substantial damage to the airplane’s belly skin and outer surfaces of the landing gear doors. This damage, in addition to the lack of damage to the landing gear extension and retraction push rods, was indicative of the landing gear being retracted and the doors closed at the time of impact. Additionally, during the examination the landing gear was cycled several times, with no anomalies noted.
Probable cause
The pilot’s failure to lower the landing gear prior to 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: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
