THE CREW HAD PLANNED ON MAKING AN ILS APCH TO RWY 6, BUT THE RVR WAS ONLY 2800' & A MIN RVR OF 4000' WAS REQD FOR THAT RWY. THE CREW ELECTED TO LND ON RWY 24, SINCE 1/2 MI VIS WAS SUFFICIENT FOR THAT RWY. HOWEVER, THE APCH WAS MADE WITH A QTRG TAIL WND & APRX 10 KTS ABV VREF.

- 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.
