## Discrepancy

ON WALK AROUND BEFORE FLIGHT A VERY SMALL POOL OF FRESH FUEL WAS DISCOVERED DRIPPING FROM BOTTOM OF LT ENG COWL, UPON FURTHER EXAMINATION A BRASS FUEL FITTING IN FUEL CONTROL ASSY.  HAD CRACKED IN THE UPPER THREADED PORTION CAUSING FUEL TO LEAK FROM ENG JUST AHEAD AND ABOVE TURBOCHARGER.  HIGH POTENTIAL RISK FOR IN FLIGHT FIRE IF IT HAD GONE UNDETECTED.
