A C525 WITH A BRAKE RIGGING PROB VEERED OFF THE RWY DURING LNDG DUE TO UNCTLABLE BRAKING. THE ACFT WAS NOT DAMAGED.

Narrative

THE INCIDENT ACFT WAS A CITATION CJ-3; 525B-123 WITH 3 SOULS ON BOARD. TOUCHDOWN ON RWY WAS NORMAL. FLAPS WERE MOVED TO GND POS AND SPD BRAKES WERE EXTENDED NORMALLY. INITIAL BRAKING WAS EVEN WITH GOOD RATE OF DECELERATION. BRAKING WAS CONTINUED AND AS THE ACFT SLOWED IT BEGAN TO PULL TO THE R. I STEERED L AND BRAKED HARDER. THE ACFT PULLED R EVEN MORE AND WAS NOT SLOWING NORMALLY ANYMORE. MAX BRAKING EFFORT AND FULL L STEERING DID NOT CORRECT THE SITUATION. EMER BAKES WERE USED TO STOP THE ACFT AT THE INTXN OF RWY 1R AND TXWY M6 WITH THE NOSEWHEEL 2 FT OFF THE HARD SURFACE. ENGS WERE SHUT DOWN. WE PUSHED THE ACFT BACK ONTO THE HARD SURFACE BY HAND; RESTARTED THE ENGS; AND TAXIED TO THE PARKING RAMP VERY SLOWLY. NO DAMAGE TO THE ACFT WAS FOUND. SUPPLEMENTAL INFO FROM ACN 719977: DURING THE POSTFLT MAINT IT WAS DISCOVERED THAT THE BRAKE RIGGING AND BRAKE STACK TORQUE CONTRIBUTED TO THIS EVENT. BRAKE RIGGING PROCS HAVE BEEN REVIEWED AND STEPS PUT INTO PLACE TO PREVENT ANOTHER SIMILAR OCCURRENCE.
