NTSB narrative
The commercial pilot was landing with a 25 knot, gusting, crosswind. He told the NTSB investigator-in-charge that due to turbulence he had slowed the airplane and extended 20 degrees of flaps while in cruise flight. His normal habit was to extend the landing gear to slow the airplane prior to flap extension. He stated that he forgot to extend the landing gear, heard the 'gear up' warning horn too late to go-around, and landed with the wheels retracted.
Probable cause
The pilot's failure to extend the landing gear prior to landing. Factors associated with this accident were the pilot's interference with his normal habit pattern, turbulence, and the crosswind condition during 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 1998-09-26.
