## Discrepancy

CUN - FLT 1607 - WHILE LOWERING LANDING GEAR ON APPROACH INTO CUN, THE CREW RECEIVED A 3-GREEN LIGHT INDICATION, BUT, ALSO, THREE RED LIGHTS. THE GEAR WAS RECYCLED THREE TIMES WITH THE SAME INDICATION OCCURRING.  PER ATC INSTRUCTIONS, CREW SHOT A MISSED APPROACH AND DID THREE CIRCLES SOUTH OF THE AIRPORT.  WHILE HOLDING, THE CREW FOUND THE GEAR HANDLE STICKING.  ONCE  THE GEAR HANDLE WAS PUSHED IN, THEY RECEIVED THE NORMAL THREE-GREEN LIGHT INDICATION.  THE FLIGHT LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE CLEANED THE PROXIMITY MICROSWITCHES AND TIGHTENED CONNECTORS.  OPS CHECK OK.  (X)
