## Discrepancy

NON-ETOPS FLIGHT 913 HNL-LIH, ON APPROACH TO LIH, THE CREW PLACED THE LANDING GEAR HANDLE TO THE DOWN POSITION AND NOTED THAT THE LEFT MAIN LANDING GEAR INDICATION FAILED TO SHOW DOWN AND LOCKED.  THE CREW DECLARED AN EMERGENCY AND ELECTED TO RETURN TO HNL.  ON APPROACH TO HNL, WHEN THE LANDING GEAR WAS LOWERED AGAIN, ALL THREE LANDING GEAR INDICATED DOWN AND LOCKED.  THE CREW LANDED IN HNL WITHOUT FURTHER INCIDENT.  MAINTENANCE ADJUSTED THE LEFT DOWN LOCK SENSOR PER AMM 32-61-31 AND COMPLETED A LANDING GEAR SWING TEST WITH ALL CHECKS SATISFACTORY.  THE AIRCRAFT WAS RETURNED TO SERVICE.
