## Discrepancy

(CAN) FOUND METAL CONTAMINATION ON OIL FILTER ELEMENT.  MFG LAB REPORTS METAL AREA MS 6274 STEEL LIKELY FROM CAMSHAFT AND AMS 4280 ALUMINUM FROM CRANKCASE.  ENGINE WAS REMOVED AS PRECAUTIONARY INVESTIGATION DUE TO SIMILAR METAL CONTAMINATION AND REPAIR ABOUT 100 HOURS AGO.  FURTHER DETAIL WILL BE SUBMITTED AFTER INVESTIGATION BY MFG.
