## Discrepancy

WHILE THE ACFT WAS BEING PARKED AFTER A ROUTINE FLIGHT, THE PILOTS NOTED OIL STREAKING DOWN THE LT SIDE OF THE FUSELAGE, FROM THE LT SIDE OF THE TOP COWLING ALL THE WAY BACK TO THE TAIL. OIL ALSO BEGAN DRIPPING DOWN ONTO THE NLG.  MAINTENANCE REMOVED THE TOP COWLING AND DISCOVERED THE OIL WAS COMING FROM THE PLEATS IN THE OIL COOLER.  THE LEAK ALLOWED SEVERAL QUARTS OF OIL TO ESCAPE ON THE 2 HOUR FLIGHT.
