THE AIRCRAFT LANDED UNEVENTFULLY AT CLT AND WAS TOWED BACK TO THE GATE AFTER ENGINE SHUTDOWN.  MAINTENANCE PERSONNEL TROUBLESHOT THE SYSTEM AND FOUND A HYDRAULIC LEAK COMING FROM A CRUSHED O-RING ON A T-FITTING REDUCER ON A LINE GOING TO THE HYDRAULIC FILTER IN THE ELFT WHEEL WELL.  MAINTENANCE REMOVED AND REPLACED THE O-RING AND SERVICED THE NR 1 HYDRAULIC SYSTEM AND THE SYSTEM LEAK CHECKED GOOD AND THE AIRCRAFT WAS RETURNED TO SERVICE.  (M)
