## Discrepancy

CREW REPORTED THAT WHILE ON APPROACH AFTER EXTENDING THE LANDING GEAR, THE NOSE LANDING GEAR WOULD NOT INDICATE DOWN AND LOCKED EVEN AFTER FOLLOWING THE QRH PROCEDURES.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE PERFORMED FIM TASK 32-32-00-810-803-A AND FOUND THE NOSE WHEEL DOWNLOCK PROX SWITCHES BAD AND REPLACED BOTH ALONG WITH THE NOSE LANDING GEAR DOWNLOCK HARNESS.
