## Discrepancy

FLIGHT 1870  EN-ROUTE, AFTER ROTATION, THE FLIGHT CREW HEARD A UN-NORMAL CLUNK.  THE GEAR HANDLE WAS PLACED UP.  THE GEAR INDICATORS SHOWED GREEN SOLID ALL 3 & FLASHING RED ON NOSE & RT MAIN GEAR.  ALSO, A GEAR UNSAFE ECAM MSG CAME ON.  THE CREW TRIED CYCLING THE GEAR, BUT WAS UNSUCCESSFUL.  THE FLIGHT DECLARED AN EMER, RETURNED & DID A FLYBY OF THE TOWER TO CONFIRM THAT THE GEAR WAS DOWN.  THE FLIGHT LANDED WITHOUT FURTHER INCIDENT.  REPLACED NLG EXTENSION PROXIMITY SENSOR 25GA.  PERFORMED A GEAR SWING & FUNCTIONAL CHECKS WITH NO ABNORMAL INDICATIONS OR NOISE NOTED.
