ACR LGT ACFT R MAIN LNDG GEAR TIRES BLEW-OUT DURING LNDG DUE TO MALFUNCTIONING ANTISKID SYS.

Narrative

A NORMAL APCH WAS BEING CONDUCTED TO RWY 30L AT STL. THE LNDG GEAR WAS EXTENDED AT 1500 FT ABSOLUTE. IT WAS NOTED THAT THE R INBOARD ANTI-SKID INDICATOR DID NOT INDICATE RELEASE. ALL OTHER INDICATIONS WERE NORMAL. FLT MANUAL AMPLIFICATION WAS CONSULTED CONFIRMING THE CREW'S INTENTION TO CONDUCT A LNDG WITH THE ANTI-SKID SWITCH ON. WE PLANNED ON NO BRAKING UNTIL AFTER SPOILER AND REVERSER DEPLOYMENT WITH THE ACFT SLOWED TO NEAR TAXI SPD. SHORTLY AFTER A SMOOTH TOUCHDOWN; IT WAS OBVIOUS DUE TO LATERAL CONTROL DIFFICULTY AND EXTREME ROUGHNESS OF RIDE THAT ONE OR MORE TIRES ON THE R HAND TRUCK HAD FAILED. THE ACFT DECELERATED RAPIDLY TO A CTLED STOP AT THE INTXN OF 30L AND TAXIWAY 'E'. BRAKES WERE NOT USED. DURING ROLLOUT THE TWR VOLUNTEERED THAT SMOKE FIRE WAS VISIBLE IN THE R WHEEL AREA AND ADDITIONALLY THAT FIRE EQUIP 'WAS ROLLING'. (WE HAD STOPPED PRACTICALLY ABEAM THE FIRE FIGHTING FACILITY). COINCIDENT WITH CESSATION OF MOVEMENT THE FE BEGAN THE 'BRAKE FIRE/SMOKE' CHKLIST. WHEN THE 'EVALUATE NEED TO EVAC' CHALLENGE WAS OFFERED; THE FOLLOWING ITEMS WERE INITIATED AND/OR REALIZED BY THE CAPT: THE TWR WAS RECONTACTED BY THE CAPT WHO WAS TOLD THAT THE SMOKE HAD SUBSIDED AND THAT 'THINGS LOOKED OK'. SIMULTANEOUSLY THE FO LOOKED OUT HIS WINDOW; THEN OPENED IT; LEANED OUT AND RPTED 'NO FIRE OR SMOKE VISIBLE'. THE FE WAS DISPATCHED TO OPEN AND PEER OUT OF THE R1 DOOR. THE GND FIREMAN GAVE THE OK SIGNAL TO THE CAPT (FIRE TRUCKS WERE ALREADY ON THE SCENE). THE DECISION WAS MADE NOT TO EVACUATE. 2 PA ANNOUNCEMENTS WERE MADE INSTRUCTING THE PAX TO REMAIN SEATED AND THAT EVERYTHING WAS UNDER CTL. THE L1 FLT ATTENDANT WAS CALLED TO THE COCKPIT TO CONFIRM THAT AN EVAC WOULD NOT BE NECESSARY AND TO RECEIVE A BRIEFING ON OUR STATUS. THE PAX WERE DEPLANED IN APPROX 20-25 MINS VIA MOBILE LOUNGE WITHOUT INCIDENT. THEY APPEARED TO BE CALM AND IN A GOOD STATE OF MIND AND GENERALLY QUITE COMPLIMENTARY. MOST IMPORTANT THERE WERE NO INJURIES. TRUCK FAILURE WAS DUE TO LOCKED WHEEL(S) ON LNDG. SUGGEST THIS POSSIBILITY BE ADDED TO AMPLIFICATION.
