## Discrepancy

UPON LANDING, GEAR EXTENSION FOR LANDING AT DTW, NOSE WHEEL LIGHT DID NOT SHOW GREEN.  RECYCLED GEAR AND GOT ALL NORMAL INDICATION.  FLIGHT LANDED WITHOUT INCIDENT.  MAINTENANCE SWUNG GEAR BUT COULD NOT DUPLICATE PROBLEM.  REPLACED NOSE GEAR DOWNLOCK SWITCH.  GEAR OPERATION CHECKED OK.
