Narrative:

Aircraft was dispatched with anti-skid inoperative. Taxi out and takeoff were routine. Upon touchdown at dfw on runway 18R, the captain deployed speed brakes, extended reversers and brakes were not used. We were informed by dfw tower (seemingly the instant we touched down) that we had blown a tire. The aircraft shuddered continuously until we came to a stop on taxiway east, clear of runway 18R. Upon closer inspection by another aircraft, we were informed that both the #2 and #4 main tires had blown. Checklists were accomplished normally and when buses arrived, passenger and crew were off-loaded without incident. It appears to me that there must have been something wrong with the braking system that turning the anti-skid system switch to off did not fix. The captain (PF) has stated that he had not yet applied the brakes and the mechanics reported having difficulty changing the tires. The brakes seemed to be applied, even with the parking brake released. I recommend more careful evaluation before placarding a malfunctioning brake system with 'anti-skid inoperative.' also, it seems the time period allowed to make the repair is excessive. I certainly will be more involved in researching the write-up that leads to an anti-skid system inoperative placard.

Original NASA ASRS Text

Title: FLC OF B727-200 DISPATCHED WITH ANTI-SKID INOP. ON LNDG TWR INFORMS THEM THEY HAVE BLOWN TIRES. SPD BRAKES DEPLOYED AND REVERSERS USED BUT NOT BRAKES.

Narrative: ACFT WAS DISPATCHED WITH ANTI-SKID INOP. TAXI OUT AND TKOF WERE ROUTINE. UPON TOUCHDOWN AT DFW ON RWY 18R, THE CAPT DEPLOYED SPD BRAKES, EXTENDED REVERSERS AND BRAKES WERE NOT USED. WE WERE INFORMED BY DFW TWR (SEEMINGLY THE INSTANT WE TOUCHED DOWN) THAT WE HAD BLOWN A TIRE. THE ACFT SHUDDERED CONTINUOUSLY UNTIL WE CAME TO A STOP ON TXWY E, CLR OF RWY 18R. UPON CLOSER INSPECTION BY ANOTHER ACFT, WE WERE INFORMED THAT BOTH THE #2 AND #4 MAIN TIRES HAD BLOWN. CHKLISTS WERE ACCOMPLISHED NORMALLY AND WHEN BUSES ARRIVED, PAX AND CREW WERE OFF-LOADED WITHOUT INCIDENT. IT APPEARS TO ME THAT THERE MUST HAVE BEEN SOMETHING WRONG WITH THE BRAKING SYS THAT TURNING THE ANTI-SKID SYS SWITCH TO OFF DID NOT FIX. THE CAPT (PF) HAS STATED THAT HE HAD NOT YET APPLIED THE BRAKES AND THE MECHS RPTED HAVING DIFFICULTY CHANGING THE TIRES. THE BRAKES SEEMED TO BE APPLIED, EVEN WITH THE PARKING BRAKE RELEASED. I RECOMMEND MORE CAREFUL EVALUATION BEFORE PLACARDING A MALFUNCTIONING BRAKE SYS WITH 'ANTI-SKID INOP.' ALSO, IT SEEMS THE TIME PERIOD ALLOWED TO MAKE THE REPAIR IS EXCESSIVE. I CERTAINLY WILL BE MORE INVOLVED IN RESEARCHING THE WRITE-UP THAT LEADS TO AN ANTI-SKID SYS INOP PLACARD.
