## Discrepancy

(CAN) ON SHUTDOWN, ON WED FEB 10 2010, THE CREW NOTICED A LARGE AMOUNT OF OIL LEAKING FROM THE LT ENG COWLS. UPON FURTHER INSP IT WAS DETERMINED THAT THE O-RING SEALING THE OIL FILTER HSG ADAPTER TO THE ENGINE HAD BEEN PINCHED AND SUBSEQUENTLY SLICED ON INSTALLATION. THIS ALLOWED EXCESS AMOUNTS OF OIL TO VACATE THE ENGINE. THIS IS A FRESHLY O/H ENGINE AND WAS INSTALLED ON WING JUST A DAY PRIOR TO THE INCIDENT. MX CREWS REPLACED THE FAULTY O-RING AND PERFORMED GROUND RUNS TO ENSURE NO FURTHER LEAKAGE. THE ACFT WAS RETURNED TO SERVICE AND NO SIMILAR EVENTS HAVE BEEN INCURRED. (TC 20100212005)
