## Discrepancy

RAN ENGINE UP TO CHECK MAG DROP AND ENGINE OIL WAS OBSERVED TO BE DRIPPING OUT OF PORT SIDE WING ROOT.  REMOVE INSP PLATES AND FOUND THAT THE .2500" ALUMINUM TUBING (PN 5600107-11) WAS ROUTED OVER THE TOP OF THE 3" SCAT TUBING.  THE WIRE IN THE SCAT TUBING HAD CHAFFED A HOLE IN THIS .2500" ALUMINUM OIL PRESSURE LINE THAT RUNS FROM THE ENGINE TO THE COCKPIT.  INSPECTED STARBORD INSTALLATION AND WAS ROUTED SAME WAY.  IT WAS ROUTED TO PREVENT CHAFING.
