NTSB narrative
THE PILOT WAS CLEARED FOR AN ILS RUNWAY 6 APPROACH AND REPORTED THAT HE HAD THE RUNWAY IN SIGHT ABOVE THE DECISION HEIGHT. SNOW WAS FALLING. AFTER A 'SUCCESSFUL' APPROACH, THE AIRPLANE TOUCHED DOWN IN THE 'TOUCHDOWN ZONE.' SPOILERS, THRUST REVERSERS, AND BRAKES WERE APPLIED, BUT THE AIRPLANE 'STARTED TO DRIFT TO THE RIGHT.' THE AIRPLANE IMPACTED A SNOWBANK ON THE RIGHT SIDE OF THE RUNWAY. ITS LEFT MAIN LANDING GEAR COLLAPSED AND THE FUSELAGE KEEL BEAM WAS DAMAGED. BRAKING ACTION WAS REPORTED AS 'NIL' BY THE PILOT. THE RUNWAY HAD 'TWO TO THREE INCHES' OF WET SNOW. IT WAS CLOSED AND PLOWED IMMEDIATELY FOLLOWING THE ACCIDENT. THE TOWER CONTROLLER HAD TRANSMITTED TO THE PILOTS 'LAST BRAKING ACTION FAIR BY A WESTWIND ABOUT 20 MINUTES AGO.' THE ATIS INFORMATION INCLUDED 'APPROACH LIGHTS FOR RUNWAY 6 HAVE BEEN DECOMMISSIONED.'
Probable cause
IMPROPER PLANNING OR DECISION BY THE PILOT IN COMMAND (PIC). FACTORS RELATED TO THE ACCIDENT WERE: DARKNESS, THE ADVERSE WEATHER CONDITIONS, AND THE RUNWAY/TERRAIN CONDITION.

Source notes (4)
- 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 1993-03-18.
