NTSB narrative
FLT 1206 WAS ON FINAL FOR A CAT II ILS RWY 2L APCH. THE LAST RPRTD RVR PRIOR TO LANDING WAS 700 FT, & 1200 FT RVR WAS RPRTD AS THE FLT CROSSED THE OUTER MARKER. MINIMUMS FOR THE APCH WERE 1200 FT RVR. ON SHORT FINAL, THE CAPT SAW APCH LIGHTS & DISCONNECTED THE AUTOPILOT AS THE ACFT DSCNDD BELOW 200 FT AGL. THE ACFT TOUCHED DOWN 408 FT SHORT OF THE RWY THRESHOLD, DAMAGING THE APCH LIGHTING SYS & THE ACFT. DFDR READOUT REVEALED THE ACFT RATE OF DSCNT INCREASED FROM 720 FPM TO 1400 FPM AFTER THE AUTOPILOT WAS DISCONNECTED, WHILE AIRSPEED REMAINED CONSTANT. INSPN OF THE ACFT NAV EQUIP & ARPT NAV AIDS REVEALED NO EVIDENCE OF MALFUNCTION. ALTHOUGH THE CAPT STATED THAT HE HAD THE APCH LIGHTS VISUALLY, HE WAS UNAWARE THE ACFT HAD LANDED SHORT. THE FLT ENGINEER STATED HE FELT THE ACFT HAD INDEED LANDED SHORT. THE CAPT DISCONNECTED THE AUTOPILOT AT ABOUT 200 FEET AGL, ALTHOUGH COMPANY PROCEDURES REQUIRED USE OF THE AUTOPILOT DOWN TO DECISION HEIGHT (100 FT AGL).
Probable cause
THE CAPTAIN'S FAILURE TO MAINTAIN A PROPER GLIDE PATH AFTER DISCONNECTION OF THE AUTOPILOT DURING THE FINAL APPROACH. FACTORS IN THIS ACCIDENT WERE: THE CAPTAIN'S FAILURE TO FOLLOW COMPANY PROCEDURES FOR CATEGORY II APPROACHES, THE FIRST OFFICER'S FAILURE TO ADEQUATELY MONITOR THE APPROACH DURING THE FINAL PHASE, PRIOR TO TOUCHDOWN, AND THE LOW VISIBILITY AT THE TIME OF THE ACCIDENT.

- 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.
