Narrative:

After concluding a maintenance test flight on a hawker 700 I called ZZZ tower, (also the departure airport) received clearance to land on runway 12, executed a normal approach, and landed on runway 12 at ZZZ, united states. I landed on the centerline, at vref (110 KTS) as the nosewheel touched down I began to apply the brakes and the aircraft immediately began a right turn, I released the brakes immediately, added power and the aircraft left the runway on the right. I immediately closed both throttles, (idle) grabbed the tiller, turned left to straighten out the aircraft and applied full brakes. We were now paralleling the runway in the grass. We went over a taxiway perpendicular to our ground run and stopped on other side of the taxiway just short of another perpendicular taxiway. I taxied (right turn) onto the taxiway, stopped the aircraft, walked around and saw no visible damage. Aircraft was then taxied back to hangar for complete inspection. Preliminary investigation indicates that an anti-skid malfunction may have occurred. ATC personnel at ZZZ filed this as a local incident only. At this time damage appears to be minimal, 2 tires and 1 fan blade on engine.

Title: H25B CREW WENT OFF THE RWY AFTER THE ACFT PULLED UNCONTROLLABLY TO THE R.

Narrative: AFTER CONCLUDING A MAINT TEST FLT ON A HAWKER 700 I CALLED ZZZ TWR, (ALSO THE DEP ARPT) RECEIVED CLRNC TO LAND ON RWY 12, EXECUTED A NORMAL APCH, AND LANDED ON RWY 12 AT ZZZ, UNITED STATES. I LANDED ON THE CTRLINE, AT VREF (110 KTS) AS THE NOSEWHEEL TOUCHED DOWN I BEGAN TO APPLY THE BRAKES AND THE ACFT IMMEDIATELY BEGAN A R TURN, I RELEASED THE BRAKES IMMEDIATELY, ADDED PWR AND THE ACFT LEFT THE RWY ON THE R. I IMMEDIATELY CLOSED BOTH THROTTLES, (IDLE) GRABBED THE TILLER, TURNED L TO STRAIGHTEN OUT THE ACFT AND APPLIED FULL BRAKES. WE WERE NOW PARALLELING THE RWY IN THE GRASS. WE WENT OVER A TXWY PERPENDICULAR TO OUR GND RUN AND STOPPED ON OTHER SIDE OF THE TXWY JUST SHORT OF ANOTHER PERPENDICULAR TXWY. I TAXIED (R TURN) ONTO THE TXWY, STOPPED THE ACFT, WALKED AROUND AND SAW NO VISIBLE DAMAGE. ACFT WAS THEN TAXIED BACK TO HANGAR FOR COMPLETE INSPECTION. PRELIMINARY INVESTIGATION INDICATES THAT AN ANTI-SKID MALFUNCTION MAY HAVE OCCURRED. ATC PERSONNEL AT ZZZ FILED THIS AS A LCL INCIDENT ONLY. AT THIS TIME DAMAGE APPEARS TO BE MINIMAL, 2 TIRES AND 1 FAN BLADE ON ENG.
