## Discrepancy

PDIS  668     32-30  3276     20MAR21  GSO   ON APPROACH TO KGSO THE GEAR DID NOT EXTEND IN SYS  2. THERE WAS NO ECAM MESSAGE. THE ONLY INDICATION  WE RECEIVED WERE THREE UNLK LIGHTS ON THE LANDING  GEAR PANEL AND OVERHEAD PANEL. THERE WAS NO NOISE  INDICATING GEAR MOVEMENT. WE DISCONTINUED THE  APPROACH. FOUND A SAFE AREA TO WORK THE PROBLEM. WE  TRIED SYS 1 AND HAD SOME INDICATIONS. NEVER IN  EITHER POSITION DID WE GET THE SOUND OF GEAR OR  GEAR DOORS MOVING. WE DECLARED AN EMERGENCY WITH  ATC. TALKED WITH MAINTENANCE , OPS & GOC. AFTER  SEVERAL MINUTES THE ECAM DIRECTED US TO LANDING  GEAR GRAVITY EXTENSION CHECKLIST. WE ACCOMPLISHED  THIS AND LANDED.
