## Discrepancy

AFTER TAKEOFF WHEN GEAR SELECTED UP, RECEIVED "L/G GEAR NOT UPLOCKED" AND "L/G DOOR NOT CLOSED" MESSAGES. CYCLED GEAR HANDLE TWICE WITH THE SAME RESULTS. DIVERTED TO PDX WITH NORMAL GEAR DOWN INDICATIONS AND LANDED WITHOUT INCIDENT.    MAINTENANCE REPLACED THE LEFT MAIN GEAR DOOR PRIXIMITY SENSOR 33GA. OPERATIONAL CHECK OK.
