## Discrepancy

THE LEFT MLG DID NOT INDICATE DOWN & LOCKED WHEN GEAR WAS EXTENDED ON APPROACH TO IAH.  MANUAL EXTENSION WAS PERFORMED AND YAW  WAS FELT WHEN LEFT MAIN EXTENDED.  THE GEAR INDICATED 3 GREEN AND LANDING WAS NORMAL.  THE GEAR WAS SWUNG SEVERAL TIMES WITH NO FAULTS NOTED.  THE LEFT MAIN GEAR UPLOCK ACTUATOR WAS REMOVED AND REPLACED AS A PRECAUTIONARY MEASURE IAW M/M 32-32-41.  OPERATIONAL CHECKS WERE GOOD.
