## Analysis

ABOUT 26 MIN BEFORE LANDING CREW RECEIVED SIGMET 1C ADVISING OF LINE OF THUNDERSTORMS FROM MILWAUKEE TO ST. LOUIS MOVINGSE AT 15 KTS. THEY ALSO BECAME AWARE OF A THUNDERSTORM WEST OF ARPT. AT ABOUT 20 MI NE OF ARPT THEY COULD SEE THE STORM VISUALLY & ON RADAR WEST OF ARPT. ABOUT 15 MI OUT CREW CEASED LOOKING AT RADAR DUE TO INCREASING WORKLOAD & GROUNDCLUTTER. RAIN INCREASED IN INTENSITY DURING FINAL APPROACH. ACFT LANDED, OVERRAN RWY & HIT APCH LIGHT. CREW DID NOT CONSULT LANDING FIELD LENGTH CHART IN COMPANY OPS MANUAL. CHART INDICATES A STOPPING DISTANCE OF 7,930 FT FROM INITIAL BRAKE APPLICATION FOR A 'VERY WET' RWY. ANOTHER FLT WHICH WAS ARRIVING IN THE ARPT AREA AT THE TIME OF THE ACCIDENT RECEIVED VECTORS NORTH OF THE ARPT & HELD FOR ABOUT 10 MIN. THEY THEN FLEW '...ON THE BACK SIDE OF TH WEATHER FOR AN APPROACH TO RUNWAY 14R...' RWY 27L, 10141 FT LONG, WAS AVAILABLE.
