Narrative:

After completion of the landing rollout on runway 32, a 180 degree turn was initiated to return to a taxiway. The aircraft's turn straightened out. Brake was applied in the direction of the turn. The aircraft began rolling off the runway. Both brakes were applied as the nose wheel sunk into a ditch off the edge of the runway. The nose wheel broke off. The right propeller hit the pavement at idle. The left propeller hit the dirt at idle. Visual inspection revealed the steering linkage was broken which caused the aircraft to veer off the runway. No persons were injured. There was minimal damage to the aircraft.

Title: ATX MEDIUM PISTON TWIN HAS NOSE WHEEL STEERING FAILURE, EXPERIENCES RWY TXWY EXCURSION.

Narrative: AFTER COMPLETION OF THE LNDG ROLLOUT ON RWY 32, A 180 DEG TURN WAS INITIATED TO RETURN TO A TXWY. THE ACFT'S TURN STRAIGHTENED OUT. BRAKE WAS APPLIED IN THE DIRECTION OF THE TURN. THE ACFT BEGAN ROLLING OFF THE RWY. BOTH BRAKES WERE APPLIED AS THE NOSE WHEEL SUNK INTO A DITCH OFF THE EDGE OF THE RWY. THE NOSE WHEEL BROKE OFF. THE RIGHT PROPELLER HIT THE PAVEMENT AT IDLE. THE LEFT PROPELLER HIT THE DIRT AT IDLE. VISUAL INSPECTION REVEALED THE STEERING LINKAGE WAS BROKEN WHICH CAUSED THE ACFT TO VEER OFF THE RWY. NO PERSONS WERE INJURED.
