## Discrepancy

MAIN VACUUM FILTER WAS LOCATED UNDER WINDSHIELD FORWARD SEAM.  DUE TO HEAVY RAINFALL AND A LEAKING SEAL BETWEEN WINDSHIELD AND BOOT COWL, THE MAIN FILTER BECAME SATURATED WITH WATER.  ON START-UP THE GYROS FILLED WITH WATER.   REPAIRED AND REPLACED GYROS.  DRIED OUT SYSTEM, AND REPLACED FILTERS.  MOVED MAIN FILTER UNDER WINDSHIELD AND SEALED FWD WINDSHIELD WITH RTV.  SYSTEM TEST OK.
