ABORTED TKOF WHEN ACR MLG SUFFERS PRIMARY ELECTRICAL PWR SUPPLY PROBLEM AND LOSES ALL ELECTRICAL ON TKOF. BLOWS TIRES.

Narrative

ON TKOF ROLL -- RWY 26L ATL. THE ACFT EXPERIENCED COMPLETE ELECTRICAL FAILURE. AN ABORT WAS INITIATED IMMEDIATELY. ACFT SPD HAD REACHED 90-100 KTS PRIOR TO THE ABORT. DURING THE ABORT; BOTH L MAIN TIRES BLEW OUT. BACK-UP PWR WAS SELECTED AND TWR ADVISED OF OUR ABORT. TWR WAS AWARE OF OUR ABORT AND TOLD US THEY HEARD 2 LOUD BANGS (TIRES BLOWING) AND THAT WE WERE TRAILING SPARKS. WE STOPPED THE ACFT HALFWAY OFF THE RWY ON A HIGH SPD TAXIWAY. AFTER FURTHER DISCUSSION WITH TWR AND A VISUAL INSPECTION OF THE L MAIN FOR ANY POSSIBLE FIRE WE DECIDED TO RULE OUT AN EMER EVAC. EMER CREWS RESPONDED AND THE FIRE CHIEF RPTED THAT THE ACFT APPEARED SAFE. BUSSES WERE SUMMONED AND PAX DEPLANED THROUGH THE AFT AIRSTAIRS WITH NO INCIDENT OR INJURY. ALL ACFT INDICATIONS WERE NORMAL UP TO TKOF ROLL. APU WAS NOT RUNNING FOR TKOF DUE TO HIGH CEILINGS BUT WOULD HAVE SUPPLIED BACK-UP PWR; SINCE WE STARTED THE APU AFTER THE ABORT AND IT RE-PWRED THE ACFT ELECTRICAL SYS. SUPPLEMENTAL INFO FROM ACN 222850: I INITIATED AN ABORT WITH APPROX HALF OF THE 10000 FT RWY LEFT. THE RWY WAS DAMP DUE TO LIGHT RAIN WHICH HAD BEEN FALLING OFF AND ON ALL DAY. SHORTLY AFTER STARTING THE ABORT BOTH L MAIN TIRES BLEW. WHEN STOPPED; I OPENED THE L COCKPIT WINDOW AND COULD SEE NOTHING TO INDICATE AN EVAC WAS NECESSARY. WE CHKED WITH THE FLT ATTENDANTS AND THEY CONCURRED THAT THERE WAS NO SMOKE OR FIRE. EMER EQUIP RESPONDED VERY FAST AND ALSO SAID EVERYTHING WAS SECURE. EVEN THOUGH WE WERE REASONABLY SURE THAT AN EVAC WAS NOT GOING TO BE NECESSARY WE WENT THROUGH THE CHKLIST UP TO THE POINT OF ORDERING THE EVAC. THE FLT ATTENDANTS ALSO KEPT THE EMER SLIDES AT THE DOORS ARMED UNTIL AFTER THE EMER EQUIP ARRIVED.
