What was found
DURING ROUTINE INSPECTION, A PUDDLE OF FUEL WAS NOTICED ON THE GROUND, DIRECTLY UNDER THE ENGINE DECK DRAIN. FURTHER INSPECTION IDENTIFIED THE SOURCE OF THE LEAK AS THE FUEL CONTROL UNIT. THE FUEL CONTROL UNIT WAS LEAKING FROM THE FUEL CONTROL UNIT DRAIN. REPLACEMENT OF THE FCU WAS NECESSARY TO CORRECT THIS PROBLEM.
