Narrative:

This was a normal approach and landing with autobrakes on medium. Runway 9R was ice and snow covered but plowed, braking action was reported good for first 2/3 of runway and poor on last 1/3 by the aircraft just exiting the runway. Upon landing and rollout, I had very good deceleration to almost a complete stop. Tower asked if we were going to make taxiway F. We advised that we could and started a left turn to the 90 degree taxiway. Through about 45 degrees of aircraft turn, the nosewheel tiller was forced further left to beyond full deflection. (I believe that the plowed edge of the snow build-up caused the additional deflection). At the point when tiller went full turn, there was a 'pop' and the tiller jammed in that position. I then applied brakes to stop the aircraft, but it continued the drift towards the right edge of taxiway F. I then went into reverse thrust to about 1.4 EPR. This stopped the aircraft forward movement. The nosewheel stopped at the double yellow edge taxiway marker. (I found this out when the ground crew plowed the 6 inches of snow away for tug traction.) we then notified the tower that we were stuck and not clear of the runway. The tower had to send out a tug and a mechanic for inspection of the nosewheel steering. When the ground crew arrived they informed us that the aircraft was still completely on the taxiway. They hooked up the tow bar and straightened the nosewheel, with no damage noted. We were then towed to gate. Callback conversation with reporter revealed the following information: the reporter stated that when maintenance arrived a tow bar was attached and the nose gear centered and the steering returned to normal operation. The reporter said the aircraft did not depart the taxiway at any time. The reporter said at the gate maintenance again checked the steering and found it ok for service.

Title: AN MD SUPER 80 ON TURNING ONTO A SNOW COVERED TXWY HAD THE NOSE GEAR SLIDE UP AGAINST A SNOW BANK CAUSING THE NOSE GEAR AND STEERING TILLER TO EXCEED THE TILLER LIMITS STRANDING THE ACFT.

Narrative: THIS WAS A NORMAL APCH AND LNDG WITH AUTOBRAKES ON MEDIUM. RWY 9R WAS ICE AND SNOW COVERED BUT PLOWED, BRAKING ACTION WAS RPTED GOOD FOR FIRST 2/3 OF RWY AND POOR ON LAST 1/3 BY THE ACFT JUST EXITING THE RWY. UPON LNDG AND ROLLOUT, I HAD VERY GOOD DECELERATION TO ALMOST A COMPLETE STOP. TWR ASKED IF WE WERE GOING TO MAKE TXWY F. WE ADVISED THAT WE COULD AND STARTED A L TURN TO THE 90 DEG TXWY. THROUGH ABOUT 45 DEGS OF ACFT TURN, THE NOSEWHEEL TILLER WAS FORCED FURTHER L TO BEYOND FULL DEFLECTION. (I BELIEVE THAT THE PLOWED EDGE OF THE SNOW BUILD-UP CAUSED THE ADDITIONAL DEFLECTION). AT THE POINT WHEN TILLER WENT FULL TURN, THERE WAS A 'POP' AND THE TILLER JAMMED IN THAT POS. I THEN APPLIED BRAKES TO STOP THE ACFT, BUT IT CONTINUED THE DRIFT TOWARDS THE R EDGE OF TXWY F. I THEN WENT INTO REVERSE THRUST TO ABOUT 1.4 EPR. THIS STOPPED THE ACFT FORWARD MOVEMENT. THE NOSEWHEEL STOPPED AT THE DOUBLE YELLOW EDGE TXWY MARKER. (I FOUND THIS OUT WHEN THE GND CREW PLOWED THE 6 INCHES OF SNOW AWAY FOR TUG TRACTION.) WE THEN NOTIFIED THE TWR THAT WE WERE STUCK AND NOT CLR OF THE RWY. THE TWR HAD TO SEND OUT A TUG AND A MECH FOR INSPECTION OF THE NOSEWHEEL STEERING. WHEN THE GND CREW ARRIVED THEY INFORMED US THAT THE ACFT WAS STILL COMPLETELY ON THE TXWY. THEY HOOKED UP THE TOW BAR AND STRAIGHTENED THE NOSEWHEEL, WITH NO DAMAGE NOTED. WE WERE THEN TOWED TO GATE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THAT WHEN MAINT ARRIVED A TOW BAR WAS ATTACHED AND THE NOSE GEAR CTRED AND THE STEERING RETURNED TO NORMAL OP. THE RPTR SAID THE ACFT DID NOT DEPART THE TXWY AT ANY TIME. THE RPTR SAID AT THE GATE MAINT AGAIN CHKED THE STEERING AND FOUND IT OK FOR SVC.
