Narrative:
During maintenance acceptance flight, a normal ILS approach to landing was executed. The profile called for an antiskid braking functional check after touchdown. A normal landing was accomplished with no antiskid malfunctions apparent. After lowering the nose gear to the runway with normal landing spoilers deployed at approximately 90 KTS, gradual medium to heavy braking was initiated to verify proper antiskid operation and directional control. Failure of more than 1 tire was immediately detected by feel and sound. Braking effort was discontinued. The aircraft could not be taxied completely clear of the runway. This resulted in the closing of the runway. Postflt inspection revealed the failure of tires #1, #3, and #4. The wheels had dragged through the #3 and #4 set into the wheel rim. The damage suggests that wheels #3 and #4 never rotated after brake application. Apparently the antiskid system never released the brakes during a skidding condition. The system in use is the hytrol mark III version as installed on the DC8/63F. Wheel brake #1 apparently failed to release properly, also resulting in a blown tire. The aircraft was jacked and tires replaced then returned to the overhaul facility for maintenance action.

Title: A DC8-63F EXPERIENCED BRAKE ANTISKID FAILURE ON LNDG ROLLOUT INCURRING 3 BLOWN TIRES AND BLOCKING THE RWY.
Narrative: DURING MAINT ACCEPTANCE FLT, A NORMAL ILS APCH TO LNDG WAS EXECUTED. THE PROFILE CALLED FOR AN ANTISKID BRAKING FUNCTIONAL CHK AFTER TOUCHDOWN. A NORMAL LNDG WAS ACCOMPLISHED WITH NO ANTISKID MALFUNCTIONS APPARENT. AFTER LOWERING THE NOSE GEAR TO THE RWY WITH NORMAL LNDG SPOILERS DEPLOYED AT APPROX 90 KTS, GRADUAL MEDIUM TO HVY BRAKING WAS INITIATED TO VERIFY PROPER ANTISKID OP AND DIRECTIONAL CTL. FAILURE OF MORE THAN 1 TIRE WAS IMMEDIATELY DETECTED BY FEEL AND SOUND. BRAKING EFFORT WAS DISCONTINUED. THE ACFT COULD NOT BE TAXIED COMPLETELY CLR OF THE RWY. THIS RESULTED IN THE CLOSING OF THE RWY. POSTFLT INSPECTION REVEALED THE FAILURE OF TIRES #1, #3, AND #4. THE WHEELS HAD DRAGGED THROUGH THE #3 AND #4 SET INTO THE WHEEL RIM. THE DAMAGE SUGGESTS THAT WHEELS #3 AND #4 NEVER ROTATED AFTER BRAKE APPLICATION. APPARENTLY THE ANTISKID SYS NEVER RELEASED THE BRAKES DURING A SKIDDING CONDITION. THE SYS IN USE IS THE HYTROL MARK III VERSION AS INSTALLED ON THE DC8/63F. WHEEL BRAKE #1 APPARENTLY FAILED TO RELEASE PROPERLY, ALSO RESULTING IN A BLOWN TIRE. THE ACFT WAS JACKED AND TIRES REPLACED THEN RETURNED TO THE OVERHAUL FACILITY FOR MAINT ACTION.
