## Discrepancy

THE NR 1 TIRE THREW TREAD INTO FLAP WELL RESULTING IN A SHEARED INBOARD SPOILER RETURN LINE AND SUBSEQUENT LOSS OF A SYSTEM HYDRAULICS ON TAKEOFF.  THE AIRCRAFT WAS RETURNED TO LAX WHERE IT LANDED WITHOUT INCIDENT.  THE SPOILER LINE WAS REMOVED AND A FLEX LINE WAS INSTALLED.  A DIP WAS ISSUED TO REPLACE THE FLEX LINE WITHIN 1200 FLIGHT HOURS OR 500 FLIGHTS.  THE HYDRAULIC SYSTEM WAS SERVICED.  LEAK AND OPERATIONAL CHECKS WERE GOOD.  IN ADDITION, THE NR 1 TIRE WAS REPLACED.
