## Discrepancy

THE AIRCRAFT HAD A BRIEF HISTORY WHERE THE LANDING GEAR WAS SLOW TO EXTEND.  REPLACING THE LANDING GEAR TRANSFER VALVE DID NOT HELP.  MAINTENANCE REMOVED AND REPLACED THE NLG LOCK ACTUATOR AND NLG TRANSFER CYLINDER.  AN OPERATIONAL TEST AND GEAR SWING WERE PERFORMED IAW MM 32-31 WITH NO FAULTS NOTED.
