What was found
WHEN POWER REDUCED FROM TAXIING POWER TO IDLE QUICKLY, ENGINE MAKES A FAST TICKING SOUND. PREVIOUS OIL ANALYSIS INDICATED A SLIGHTLY HIGHER COPPER CONTENT IN THE OIL. THE ENGINE WAS RAN BRIEFLY BY TECHNICIANS, NOTED THAT THE ENGINE WAS MAKING A LOUD KNOCKING NOISE. OIL FILTER WAS PULLED AND COPPER FLAKES WERE FOUND THROUGHOUT THE FILTER. ACCORDING TO THE MANUFACTURER THERE IS ONLY ONE BEARING THAT WOULD CAUSE COPPER FLAKES LFOUND IN THE FILTER, THE CONNECTING ROD WRIST PIN BEARINGS .
