## Discrepancy

WHILE CONDUCTING A 50 HR INSP, THE LT ENGINE OIL FILTER WAS SPLIT TO VERIFY NO METAL COMTAMINATION WAS PRESENT.  THE FILTER ASSY WAS FOUND COLLAPSED. THERE WAS NO VISIBLE DAMAGED NOTED TO THE OUTER METAL CASING.  NO DAMAGE TO THE ENGINE OR ABNORMAL INDICATIONS WERE NOTED DURING FLIGHT.
