## Discrepancy

(CAN) DURING ROUTINE CPC NR 2 INSPECTION, THE ACFT OIL FILTER WAS OPENED TO CHECK FOR CONTAMINATION AND ALUMINUM WAS FOUND IN THE FILTER ELEMENT.   WE PROCEEDED TO REMOVE ENGINE CYLINDERS AND FOUND NR 1 CYLINDER PISTON PIN PLUG WORN, FURTHER INSPECTION OF CYLINDER WAS CARRIED OUT AND A GROOVE WAS FOUND NEAR THE BASE OF THE CYLINDER CAUSING THE PISTON PIN PLUG TO WEAR.
