## Discrepancy

CREW REPORTED THAT AFTER TAKEOFF THE NOSE LANDING GEAR WOULD NOT RETRACT.  THE AIRCRAFT RETURNED TO FIELD AND LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE NOSE LANDING GEAR WOW HARNESS (W019) AND THE NOSE LANDING GEAR WOW PROXIMITY SWITCH.  OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
