Narrative:
The incident aircraft was a citation cj-3; 525B-123 with 3 souls on board. Touchdown on runway was normal. Flaps were moved to ground position and speed brakes were extended normally. Initial braking was even with good rate of deceleration. Braking was continued and as the aircraft slowed it began to pull to the right. I steered left and braked harder. The aircraft pulled right even more and was not slowing normally anymore. Maximum braking effort and full left steering did not correct the situation. Emergency bakes were used to stop the aircraft at the intersection of runway 1R and taxiway M6 with the nosewheel 2 ft off the hard surface. Engines were shut down. We pushed the aircraft back onto the hard surface by hand; restarted the engines; and taxied to the parking ramp very slowly. No damage to the aircraft was found. Supplemental information from acn 719977: during the postflt maintenance it was discovered that the brake rigging and brake stack torque contributed to this event. Brake rigging procedures have been reviewed and steps put into place to prevent another similar occurrence.
Original NASA ASRS Text
Title: 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.
