## Discrepancy

AIRCRAFT LOST B-SYSTEM HYDRAULIC FLUID AND PRESSURE ON APPROACH.  THE LOSS WAS ACCOMPANIED BY ILLUMINATION OF THE HYDRAULIC PUMP LOW PRESSURE LIGHT.  MAINTENANCE FOUND ELBOW LOOSE AND A BAD O-RING ON LOWER END OF ACOUSTIC FILTER.  THE O-RING WAS REMOVED AND REPLACED AND THE ELBOW WAS TIGHTENED.  LEAK AND OPERATIONAL CHECKS WERE GOOD.
