## Discrepancy

DUTING LANDING EXTENSION ONLY THE MAINS CAME DOWN. GOT TWO GREEN FOR THE MAINS AND A YELLOW CROSS HATCHED FOR THE NOSE + "GEAR DISAGREE N".  ABOUT 30SECONDS LATER WHEN PREPARING TO DO THE CHECKLIST THE NOSEGEAR SUDDENLY EXTENDED AND WE HAD THREE GREEN. LANDED NORMALLY. CORRECTIVE ACTION; REMOVED AND REPLACED NOSE GEAR ACTUATOR & UPLOCK ACTUATOR. C/W NOSE GEAR UPLOCK ACTUATOR POST MAINTENANCE CHECKS REF. MM 32-32-15. C/W NOSE GEAR ACTUATOR POST MAINTENANCE CHECKS REF. MM 32-30-05. ALL OPS CHECKS GOOD.
