Narrative

I WAS COPLT CONDUCTING PNF DUTIES FOR APCH/LNDG INTO KSAV. AREA HAD NUMEROUS TSTM BUILDUPS AND WE WERE DEVIATING AROUND THEM AS WE SET UP FOR A VISUAL APCH TO RWY 18. AS WE APCHED 5-7 MI FROM ARPT; AT RAIN SHOWERS WERE BTWN US AND RWY. A LARGE CELL WAS W OF FIELD; SO WE DECIDED TO CONTINUE APCH AND TO MONITOR FOR POSSIBLE WINDSHEAR INDICATIONS. WE DISCOUNTED USING RWY 09/27 DUE TO CELLS OFF DEP END OF RWY 09. MOE STABILIZED VISUAL APCH TO RWY 18 (APCH 7000 FT LONG) LNDG APPROX 2000-2200 FT DOWN RWY. REALIZED ON TKOF THAT RWY HAD LARGE AMOUNT OF STANDING WATER. ACFT HYDROPLANED AUTOSPOILERS WERE SLOW TO EXTEND; AND ACFT WAS SLOW TO DECELERATE. MED AUTOBRAKES HAD BEEN SELECTED ALSO; BUT CAPT IMMEDIATELY WENT TO MAX MANUAL BRAKING. ACFT APPEARED TO BE ABLE TO STOP DURING LAST 500 FT OF ROLLOUT BUT THEN ACFT HIT PAINTGO ALGA OF RWY AND AGAIN HYDROPLANED. ACFT WENT APPROX 2 FT INTO OVERRUN ARGA HITTING ONE RWY LIGHT AND GASHING 1 NOSE WHEEL TIRE. CAUSE OF INCIDENT WAS STANDING WATER ON RWY AND EXCESSIVE HYDROPLANING. RWY WAS NOT GROOVED.
