## Discrepancy

AIRCRAFT LOST HYDRAULIC PRESSURE AT TOP OF DESCENT.  CHECKED AIRCRAFT FOR EVIDENCE OF HYDRAULIC LEAKAGE AND NO LEAKS WERE NOTED.  HYDRAULIC FLUID QUANTITY WAS NORMAL.  CHECKED HYDRAULIC PRESSURE AND POWER SYSTEM.  INSPECTED BOTH ENGINE DRIVEN HYDRAULIC PUMP CASE DRAIN FILTERS FOR CONTAMINATION AND NONE WAS NOTED.  REPLACED BOTH FILTERS FOR PRECAUTIONARY MAINTENANCE.
