## Discrepancy

(CAN) AFTER REPLACING TWO SHOCK MOUNTS AT THE LAST INSPECTION, 200HR.  DURING THE NEXT INSPECTION, 50HR IT WAS FOUND THAT THE SAME MOUNTS THAT WERE REPLACED WERE AGAIN RIPPED AND COMPLETELY SEPARATED FROM THE ATTACHING BASE.  THE ENGINE WAS INSPECTED FOR EXCESSIVE VIBRATION WHICH COULD CAUSE THE DEFECT.  NO EXCESSIVE VIBRATION WAS NOTED.
