## Discrepancy

(CAN) THE FLIGHT CREW REPORTED A SLIGHT OIL MIST ON THE WINDSCREEN OF THE AIRCRAFT. INVESTIGATION INDICATED AN OIL LEAK AT THE FRONT AREA OF THE ENGINE. THE MAINTENANCE ENGINEER DISCOVERED THAT A RIGID OIL TORQUE PRESSURE LINE HAD CHAFED ONTO A TORQUE PRESSURE FLEX LINE AT THE LOCATION OF A RETAINING BAND THAT SECURES THE FIREPROOF SLEEVE. THE CHAFING RESULTED IN A SMALL PIN HOLE ON THE RIGID LINE. BOTH THE RIGID LINE AND FLEX LINE (PILATUS P/N 946.37.74.307) WERE REPLACED AND THE AIRCRAFT WAS RETURNED TO SERVICE.
