## Discrepancy

THE A HYDRAULIC SYSTEM WAS LOST AFTER TAKEOFF FROM IAH.  THE AIRCRAFT WAS RETURNED TO IAH WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND A HOLE IN ELEVATOR LEFT PCU PRESSURE FLEX LINE.  THE FLEX LINE WAS REMOVED AND REPLACED.  IN ADDITION, THE NR 2 ENGINE DRIVEN HYDRAULIC PUMP WAS REMOVED AND REPLACED AS A PRECAUTIONARY MEASURE.  THE HYDRAULIC SYSTEM WAS SERVICED TO FULL.  OPERATIONAL CHECKS WERE GOOD WITH NO LEAKS NOTED.
