## Discrepancy

ON FLIGHT 4706, CREW REPORTED AFTER TAKEOFF LANDING GEAR WOULD NOT RETRACT.  AIRCRAFT RETURNED AND LANDED IN JFK SAFELY.  REMOVED AND REPLACED LGEU, NOSE LANDING GEAR DOWN LOCK PROX SWITCH, AND LEFT MAIN LANDING GEAR DOWN LOCK PROX SWITCH.  OPERATIONAL CHECK GOOD.  AIRCRAFT RETURNED TO SERVICE.
