## Discrepancy

2 TO 3 DAYS AFTER FLIGHT, NOTICED SIGNIFICANT OIL PUDDLE FORMED UNDER FUSELAGE AT THE MAIN CABIN DOOR STATION.  UPON VISUAL INSPECTION, LOCATED LEAK IN FLOOR AT STATION UNDER PILOT AND CO-PILOT'S SEATS.  THE SOURCE OF THE LEAK WAS BOTH THE RIGHT AND LEFT OIL PRESSURE INDICATOR SUPPLY LINES (HARD LINES) BEING CORRODED AND CRACKED AS A RESULT OF LAYING AGAINST A CABIN AIR SCAT HOSE AS THEY WERE ROUTED IN THE BUNDLE.  THE LINES ARE APPROXIMATELY 5 FEET IN LENGTH.  APPROXIMATELY .5 TO .75 QUARTS OF OIL WERE REMOVED FROM THE FLOOR SECTION ADJACENT TO THE SEAT PEDESTALS.
