NTSB narrative
The pilot was cleared to land and he placed the landing gear handle in the DOWN position. According to the pilot, the landing gear collapsed on touch down. The pilot said the landing gear warning horn never sounded. He further stated that on the previous flight, he had to cycle the flaps several times to get them to extend, and after landing, he could not retract the flaps. A post accident examination revealed the landing gear doors were closed and bore no damage. With the airplane on jacks and an external hydraulic power unit connected to the hydraulic system, the landing gear was cycled up and down 20 times with no faults detected.
Probable cause
the pilot's failure to verify that the landing gear was down and locked before landing, which resulted in a wheels-up 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2001-02-13.
