Narrative:

Normal VFR landing. Winds light to variable. First officer flying. I took control of aircraft at 60 KTS, stowed thrust reversers at 40 KTS. I was applying light to moderate braking when brakes locked slewing me to the left. Aircraft skidded left and off runway onto a taxiway. Main landing gear was 10 ft off taxiway with nose gear on the taxiway. Aircraft heading approximately 180 degrees from landing runway. Aircraft is equipped with antiskid brakes. There was no indication of a malfunction on the crew alert system. However, there was a momentary master warning. I do not know what it was. There was no aircraft damage but tires and antiskid control box were replaced. It is undergoing further testing. When the brakes locked at around 30-40 KTS, the lack of deceleration felt as if we were accelerating.

Title: MDT CREW HAD ANTISKID FAILURE DURING LNDG.

Narrative: NORMAL VFR LNDG. WINDS LIGHT TO VARIABLE. FO FLYING. I TOOK CTL OF ACFT AT 60 KTS, STOWED THRUST REVERSERS AT 40 KTS. I WAS APPLYING LIGHT TO MODERATE BRAKING WHEN BRAKES LOCKED SLEWING ME TO THE L. ACFT SKIDDED L AND OFF RWY ONTO A TXWY. MAIN LNDG GEAR WAS 10 FT OFF TXWY WITH NOSE GEAR ON THE TXWY. ACFT HDG APPROX 180 DEGS FROM LNDG RWY. ACFT IS EQUIPPED WITH ANTISKID BRAKES. THERE WAS NO INDICATION OF A MALFUNCTION ON THE CREW ALERT SYS. HOWEVER, THERE WAS A MOMENTARY MASTER WARNING. I DO NOT KNOW WHAT IT WAS. THERE WAS NO ACFT DAMAGE BUT TIRES AND ANTISKID CTL BOX WERE REPLACED. IT IS UNDERGOING FURTHER TESTING. WHEN THE BRAKES LOCKED AT AROUND 30-40 KTS, THE LACK OF DECELERATION FELT AS IF WE WERE ACCELERATING.
