## Discrepancy

AFTER 6 FLIGHTS SINCE THE LAST ISSUE WITH THE GEAR DEPLOYMENT, THE AIRCRAFT OPERATED NORMALLY. THE 6TH FLIGHT FROM KOAK INTO MYEH THE GEAR DID NOT DEPLOY AS REQUESTED. DUE TO THE LONGER FLIGHT THE AIRCRAFT DID NOT HAVE AS MUCH LUXURY TO TURN BACK TO THE STATES, THEY UTILIZED THE ALTERNATE GEAR PROCEDURE AND WERE ABLE TO DEPLOY THE GEAR AND LAND WITH NO ISSUES. MEL 32-30-01 PROVIDES OPERATIONAL PROCEDURES TO UTILIZE THE AIRCRAFT WITH THE GEAR IN THE DOWN AND LOCKED POSITION. WE UTILIZED THESE PROCEDURES TO REPOSITION THE AIRCRAFT INTO KFXE AND SEVERAL COMPONENTS WERE CHANGED DURING THIS EVENT. TROUBLESHOOTING WAS PERFORMED PER THE PROCEDURES RECOMMENDED BY BOMBARDIER FOR THE PREVIOUS EVENT AND NO NEW ISSUES WERE FOUND.THE GEAR HANDLE / TAWS PANEL AND THE LANDING GEAR SELECTOR VALVE WERE BOTH REPLACED. WE HAVE BEEN MONITORING THE SITUATION WITH BOMBARDIER OVER THE NEXT TWO FLIGHTS AND WE HAVE OPTED TO CHANGE THE PROXIMITY SYSTEM ELECTRONIC UNIT AS WELL.
