## Discrepancy

NOSE WHEEL STEERING FAILED AFTER LANDING. STOPPED ON RUNWAY, NO RESPONSE FROM RUDDER OR TILLER. DIFF BRAKING GOT US ENOUGH DEFLECTION TO CLEAR THE RUNWAY. STEERING RETURNED AFTER CLEARING THE RUNWAY WITH THE BRAKE SET. TRIED MOVING AND IT FAILED AGAIN ALMOST INSTANTLY. TOWED IN.   REMOVED NLG WBA-NOSE SQUAT SWITCH. INSTALLED A NEW NLG WBA-NOSE SQUAT SWITCH IAW MM 32-60-10. ALL POST MX CHECKS ARE GOOD WITH NO FURTHER DEFECTS NOTED.
