## Analysis

AFTER ACCELERATING TO ABOUT 153 KTS DRG THE TAKEOFF ROLL, THE #7 TIRE FAILED & THE FLT CREW ABORTED THE TAKEOFF. THE ACFT WAS STOPPED WITH APRX 3000 FT OF RWY REMAINING. DUE TO A FUEL LEAK FROM THE RIGHT WING, THE CAPT ORDERED AN EVACU- ATION FROM THE LEFT SIDE OF THE ACFT ONLY. HOWEVER, THE 2ND OFFICER DID NOT RELAY THE CAPT'S INSTRUCTIONS OVR THE PA, & WHEN THE CAPT ACTIVATED THE EVACUATION SIGNAL, THE SLIDES/RAFTS WERE DEPLOYED ON BOTH SIDES OF THE ACFT. AFTER APRX 20 OCCUPANTS HAD EVACUATED THRU EXIT 1L, THE STITCHING IN THE GRID BAR LOOPS FAILED AT THAT LOCATION. SUBSEQUENTLY, THE SLIDE/RAFT SEPARATED & 2 PAX WERE SERIOUSLY INJURED. ALSO, 1 FLT ATTENDANT HAD TAKEN A SMALL GIRL TO THE LAVORATORY & WAS NOT IN A PSN TO OPEN HER ASSIGNED EXIT (DOOR 4L); HOWEVER, A PAX WHO TRAVELED OFTEN BY AIR, OPENED THE DOOR. AN INVESTIGATION REVEALED THE #7 TIRE HAD FAILED AFTER THE INNER BEARING OF THAT WHEEL HAD FAILED. THIS CAUSED THE WHEEL & TIRE TO OVERHEAT, WHICH ALLOWED THE FUSES TO MELT & BLOW OUT. THE REASON FOR THE BEARING FAILURE WAS NOT VERIFIED.
