## Discrepancy

MAIN LANDING GEAR DOORS WERE DAMAGED DURING LANDING AND TAXIING.  GEAR DOOR OPEN LIGHT DID NOT ILLUMINATE UNTIL THE AIRCRAFT WAS ON THE GROUND.  FLIGHT CREW STOPPED ON THE TAXIWAY UNTIL A GROUND CREW COULD INSPECT THE UNDER CARRIAGE.  IT WAS DETERMINED THAT THERE WAS GEAR DOOR DAMAGE BUT OKAY TO TAXI.  MAINTENANCE REPLACED THE MAIN GEAR DOOR, DOOR LATCH, TORQUE TUBE, AND GEAR CONTROL VALVE WITH LINKAGE ALL ON THE LEFT SIDE.  THE RIGHT SIDE HAD THE SEQUENCE DRIVE ARM REPLACED.  PERFORMED BITE AND GEAR SWING CHECK.  THE AIRCRAFT RETURNED TO SERVICE.
