NTSB narrative
The pilot reported that due to the gusty crosswind conditions, he made a single 180 degree turn from downwind to final during an approach to land on runway 21. He reported that he normally lowered the landing gear on base leg. Also, he indicated that because he did not fly a normal traffic pattern, (his habit pattern was interupted, and) he failed to extend the landing gear. The airplane touched down on the runway with the landing gear retraced.
Probable cause
the pilot's failure to extend the landing gear for landing. Factors associated with the accident were: the crosswind, and the pilot not following his normal habit pattern of lowering the landing gear on base leg.

- 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.
