## Discrepancy

AFTER TAKEOFF WHEN LANDING GEAR SELECTED UP, RECEIVED "L/G DOORS NOT CLOSED" MESSAGE. THE ECAM LANDING GEAR PAGE INDICATED THE NOSE LANDING GEAR DOORS OPEN. CYCLED GEAR WITH SAME THE RESULTS. SELECTED GEAR DOWN WITH NORMAL INDICATIONS AND RETURNED TO DEPARTURE FIELD WITH A NORMAL LANDING.    MAINTENANCE REPLACED THE NOSE LANDING GEAR DOOR UPLOCK ASSEMBLY. OPERATIONAL CHECK NORMAL.
