## Discrepancy

BEGINNING DESCENT FROM 5500 FT, PASSENGERS AND CREW BEGAN TO SMELL ACRID ODOR FROM CABIN ROOF VENTS.  SECURED CABIN VENT BLOWER AND LOOKED FOR ANY SECONDARY INDICATIONS - NONE FOUND.  AFTER NORMAL LANDING AND SHUTDOWN, FURTHER INVESTIGATION  REVEALED SIGNIGICANT HYDRAULIC ACCUMULATION UNDER NR 2 HYDRAULIC MANIFOLD.  NOTIFIED MAINTENANCE.  MAINTENANCE REPLACED THE CABIN VENT BLOWER MOTOR PART NUMBER 76500-7901-103, SERIAL NUMBER 23-657 DUE TO BURNT WINDINGS AND THE NR  2 HYDRAULIC MODULE  DUE TO FILTER BOWL LEAKING - O-RING HAS BEEN REPLACED PREVIOUSLY.  THE TWO PROBLEMS WERE NOT RELATED.
