## Probable cause

The pilot's failure to extend the landing gear during landing. Contributing to the accident was the pilot’s failure to use a pre-landing checklist.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

## Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event best describes what happened.

- [Landing: Landing gear not configured](https://openairdocs.org/ntsb-events/095) (defining event); cases with it: [Cessna T210G, 1 case](https://openairdocs.org/ntsb-events/095/sequence.md?model=2073432), [All aircraft, 584 cases](https://openairdocs.org/ntsb-events/095/sequence.md)

## Analysis

The pilot reported that, while on final approach for the full stop landing, he was behind a commercial airliner. He reported that there was no turbulence and that the flaps were fully extended. The airplane subsequently landed with the landing gear retracted which resulted in substantial damage to the external longerons on the lower fuselage. The pilot indicated that he did not use a pre-landing checklist. An examination of the landing gear system revealed no preaccident mechanical failures or malfunctions that would have precluded normal operation.
