A FLT CREW AND CTLR DESCRIBE A SYS FAILURE TO AMEND NOTAM; RESULTING IN A POTENTIAL RWY CONFLICT BTWN RPTR'S ACFT AND ARPT VEHICLES ON A CLOSED RWY.

Narrative

AFTER RPTING TO DUTY; WE BEGAN PREPARATION AND FLT PLANNING FOR DEP. SAV TWR WAS CLOSED AND THE ATIS RPTED THE HRS OF OP AND ALTERNATE FREQS (NO NOTAM INFO). WE USED ZJX TO OBTAIN CURRENT WX (AGAIN; NO MENTION OF RWY CLOSURES). THE DISPATCH RELEASE WAS REVIEWED; SHOWING RWY 9 CLOSED UNTIL XE00 LOCAL; AND THEN SIGNED. WE PUSHED BACK AROUND XE43 LOCAL TIME AND ANNOUNCED ON CTAF THAT WE WERE TAXIING TO RWY 9 AND OBTAINED A CLRNC AND VOID TIME FROM ZJX. OUR VOID TIME WAS XE58. WE CONTINUED OUR TAXI TO RWY 9 AND ANNOUNCED ON CTAF THAT WE WERE TAKING RWY 9. AS WE WERE TAXIING ONTO THE NUMBERS; AN ARPT GND VEHICLE CALLED ON CTAF SAYING THAT RWY 9 WAS CLOSED. (CONTRARY TO THE TIME FRAME PUBLISHED IN NOTAM 10/099). WE DECIDED TO CLARIFY BEFORE PROCEEDING AND CONTACTED ZJX TO INFORM THEM THAT WE WOULD NOT BE MAKING OUR VOID TIME. THEY INSTRUCTED US TO CONTACT SAV UPON OPENING (ABOUT 2 MINS OUT). WE QUERIED GND PERSONNEL ON CTAF AS TO WHICH NOTAM DECLARED RWY 9 CLOSED. THEY DID NOT KNOW OTHER THAN IT WAS CLOSED UNTIL XF00 LOCAL. JUST BEFORE XF00; SAV TWR BROADCAST THAT THEY WERE OPENED AND TO CONTACT THEM IN LIEU OF ATIS DUE TO RAPIDLY CHANGING WX CONDITIONS (STILL NO MENTION OF RWY CLOSURES). WE OBTAINED WX AND A REVISED CLRNC FROM DELIVERY AND THEN CONTACTED TWR. SAV REQUESTED OUR POS; WHICH WE GAVE; AND WE THEN WERE BERATED FOR BEING THERE. WE ASKED IF WE NEEDED TO CLR THE RWY; AND WE WERE TOLD TO HOLD OUR POS. WE INQUIRED AGAIN ABOUT THE NOTAM FOR RWY 9 AND WERE TOLD IT WAS SAV LCL NOTAM 10/099 AND THAT 'IT HAD BEEN OUT FOR QUITE A WHILE.' A MOMENT LATER; WE WERE CLRED FOR TKOF. ACCELERATING THROUGH 50 KTS; SAV TWR XMITTED THAT 'THERE MIGHT BE A PLT ACTION REGARDING THIS.' WE CONTINUED THE TKOF AND CLBOUT. PRIOR TO HDOF TO DEP; I REQUESTED A PHONE NUMBER FROM SAV TWR SO THAT WE MIGHT FURTHER CLARIFY THE MATTER. UPON LNDG IN LGA; I CALLED SAV TWR AND THEY VERIFIED THAT A TYPOGRAPHICAL ERROR EXISTED. THE INTENT WAS TO HAVE THE RWY CLOSED UNTIL XB00 LOCAL. I OBTAINED THE NUMBER FOR ZJX WATCH DESK AND CALLED TO VERIFY THE DISCREPANCY WITH THEM AS WELL. SUPPLEMENTAL INFO FROM ACN 636054: SAV RWY 9/27 WAS CLOSED BY A NOTAM. THE NOTAM; AS PUBLISHED; WAS NOT CHANGED. TO THE ARPT; THE RWY WAS CLOSED BY NOTAM UNTIL XF00 LOCAL. TO THE PLT; THE RWY OPENED AT XE00 LOCAL. MACON AFSS ADMITTED TO THE ERROR. PAPERWORK ALMOST CAUSED A SERIOUS ACCIDENT.
