NTSB narrative
The pilot reported he completed the landing checklist on the downwind leg and confirmed that the landing gear was extended via the cockpit landing gear indicator lights. Additionally, he saw that the landing gear locking pins were engaged. On final approach, the pilot intended to move the flap control lever to the “full down” position; however, he inadvertently moved the landing gear control lever from the “down” position. The pilot did not perform a visual gear down check on short final. The airplane touched down with its main landing gear retracted and came to a stop on the runway. The pilot and his passenger exited the airplane and a post-accident fire ensued. The fuselage and left wing were substantially damaged by the fire. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable cause
The pilot’s inadvertent retraction of the landing gear control lever, resulting in a gear-up landing on the runway.

Source notes (5)
- 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, cause areas. 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.
- API snapshot SHA-256: b3827e20a482811bd27eef71fd7afb0c64497f03f0b8729ee928bad40213d152; retrieved 2026-09-16T17:37:25.180Z.
- Corrected after a review of the NTSB narrative, which states these values explicitly: departure. City slot holds a misspelled airport name; AMW is Ames Municipal Airport at Ames, IA.
