## Discrepancy

CLT-CHS - FLT 553 - ON FINAL APPROACH, SELECTED GEAR DOWN AND ONLY RECEIVED NOSE GEAR DOWN INDICATION.  A FLYBY OF THE TOWER CONFIRMED THAT ONLY THE NOSE GEAR WAS DOWN AND MLG DOORS WERE OPEN.  AFTER A MISSED APPROACH TO DOWNWIND, BOTH MAINS FINALLY EXTENDED.  FLIGHT LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE MLG SELECTOR VALVE AND THE PRESSURE REDUCER.  OPS AND LEAK CHECKS OK. (M)
