## Discrepancy

THE NOSE GEAR RED UNSAFE LIGHT REMAINED ILLUMINATED AFTER GEAR RETRACTION.  THE GEAR WAS CYCLED AND THE LIGHT EXTINGUISHED, BUT WENT OFF AND ON INTERMITTENTLY DURING CRUISE.  MAINTENANCE REMOVED AND REPLACED THE PROXIMITY SWITCH CONTROL AND TIGHTENED THE NOSE GEAR LOCK SENSOR TARGET.  THE NOSE GEAR WAS SWUNG SEVERAL TIMES WITH NORMAL OPERATION AND INDICATIONS.
