## Discrepancy

ON APPROACH INTO SNU, THE CREW SELECTED THE LANDING GEAR DOWN AND FAILED TO GET A DOWN AND LOCKED INDICATION ON THE LH MLG. THE CREW NOTIFIED THE TOWER AND ABORTED THE LANDING. A FLYBY PAST THE TOWER CONFORMED ALL 3 GEAR DOWN AND LOCKED. THE AIRCRAFT RETURNED TO THE PATTERN, AND LANDED SUCCESSFULLY. MAINTENANCE WAS DISPATCHED AND FOUND THE LH DOWNLOCK SWITCH CANNON PLUG LOOSE. MAINTENANCE SECURED THE CANNON PLUG AND OP CHECKED SUCCESSFULLY. THE AIRCRAFT WAS RETURNED TO SERVICE.
