NTSB narrative
The pilot reported that before landing he mistakenly positioned the four-position landing gear selector lever to the down-neutral position instead of the full-down position. He further noted that he did not notice the lack of sound and feel of the landing gear extending and the lack of an illuminated green landing gear position light; he also did not visually confirm that the main landing gear had extended. The airplane landed with the gear up, damaging several lower fuselage structural bulkheads and stringers. The pilot stated that the accident could have been prevented if he had used a checklist to ensure that the landing gear had been properly extended. He further noted that the airplane's landing gear unsafe warning horn had been inoperative for some time. A postaccident examination of the landing gear extension/retraction system did not reveal any mechanical malfunctions or failures that would have prevented the landing gear from extending normally.
Probable cause
The pilot's failure to extend the landing gear before touchdown due to his failure to use a checklist.

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: investigation status. 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.
