Contributing to the accident was the pilot's failure to utilize the pre-landing checklist. ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Landing gear system: gear extension and retract sys](https://openairdocs.org/ntsb-findings/01023230): Aircraft › Aircraft systems · Not used/operated (probable cause); cases with it: [Cessna T210L, 10 cases](https://openairdocs.org/ntsb-findings/01023230/cases.md?model=2073449), [All aircraft, 416 cases](https://openairdocs.org/ntsb-findings/01023230/cases.md) - [Use of equip/info: use of checklist](https://openairdocs.org/ntsb-findings/02063030): Personnel issues › Task performance · Pilot (probable cause); cases with it: [Cessna T210L, 3 cases](https://openairdocs.org/ntsb-findings/02063030/cases.md?model=2073449), [All aircraft, 336 cases](https://openairdocs.org/ntsb-findings/02063030/cases.md) ## Sequence of events The events NTSB coded, in order, by phase of flight. The defining event best describes what happened. - [Landing-flare/touchdown: Landing gear not configured](https://openairdocs.org/ntsb-events/095) (defining event); cases with it: [Cessna T210L, 11 cases](https://openairdocs.org/ntsb-events/095/sequence.md?model=2073449), [All aircraft, 584 cases](https://openairdocs.org/ntsb-events/095/sequence.md) ## Analysis The pilot stated that prior to entering the traffic pattern, he did not visually verify or confirm that the landing gear positioning lights indicated that the gear was extended and locked. After turning onto the base leg he deployed full flaps and conducted a memorized pre landing checklist, however he stated that he was unsure if he verified that the gear was extended. The airplane subsequently touched down with the landing gear retracted; substantially damaging the lower fuselage. The pilot reported there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. ## Factual narrative The pilot stated that prior to entering the traffic pattern, he did not visually verify or confirm that the landing gear positioning lights indicated that the gear was extended and locked.
