## Discrepancy

FUEL LEAK AT RIGHT ENGINE OIL/FUEL HEAT EXCHANGER DRAIN AND FUEL SERVO, DURING TRANSIT CHECK, IT WAS DETECTED A FUEL LEAK AT RIGHT ENGINE. MAINTENANCE PERSONNEL PERFORMED REVISION AT RIGHT ENGINE, DETECTING FUEL LEAK OUT OF LIMITS FROM MAIN OIL / FUEL HEAT EXCHANGER DRAIN AND FUEL SERVO; SO THE MAIN OIL / FUEL HEAT EXCHANGER WAS REPLACED IAW AMM 79-21-07 AND SERVO FUEL HEATER WAS REPLACED IAW AMM 73-11-07, TESTED CORRECT.
