## Discrepancy

ENROUTE TO KSMX FROM KBUR, THE NOSE GEAR STEERING INDICATION LIGHT ILLUMINATED. THE CREW RAN THE CHECKLIST, THE LIGHT DID NOT EXTINGUISH. THE CREW DECLARED AN EMERGENCY AND LANDED AT KSMX WITHOUT INCIDENT. MAINTENANCE TROUBLE SHOT AND VERIFIED THAT THE NOSE GEAR STEERING INDICATION ILLUMINATED. MAINTENANCE FOUND DEFECTIVE NOSE WHEEL STEERING CONTROL AMPLIFIER. REMOVED AND INSTALLED SERVICEABLE NOSE WHEEL STEERING CONTROL AMPLIFIER. OPERATIONAL CHECK OF NWS WAS NORMAL. THE AIRCRAFT WAS RELEASE AND RETURNED TO SERVICE.
