## Discrepancy

UPON INITIAL CLIMB, CREW NOTED GEAR HANDLE WOULD NOT MOVE FROM THE GEAR DOWN POSITION.  UNABLE TO RETRACT LANDING GEAR.  RAN QRH AND DECLARED EMERGENCY.  LANDED WITHOUT INCIDENT.  AIRCRAFT WAS FERRIED TO CMH.  MAINTENANCE REMOVED AND REPLACED THE NLG WOW NR 2 SENSOR AND NR 2 SENSOR HARNESS.  PERFORMED GEAR SWINGS AND OPS CHECK GOOD.
