What was found
(CAN) THE CREW REPORTED A HEAVY FUEL LEAK AFTER NR 2 ENGINE SHUTDOWN. THE DRAIN TANK COULD NOT TAKE THE AMOUNT OF LEAKING FUEL AND A LOT OF RESIDUAL FUEL WAS FOUND INSIDE THE LOWER COWLING. POST FLIGHT FUEL CALCULATIONS REVEALED A SPLIT OF 150KG FOR THE FLIGHT. REPLACING THE FUEL METERING UNIT, FMU, RECTIFIED THE PROBLEM. THE FMU WILL BE SENT FOR INVESTIGATION.
