## Discrepancy

DURING TRANSIT CHECK, A FUEL LEAK WAS DETECTED. MAINTENANCE PERFORMED REVISION, DETECTING FUEL LEAK THROUGH OF RIGHT ENGINE MAIN FUEL / OIL HEAT EXCHANGER; SO THE RIGHT HEAT EXCHANGER WAS REPLACED IAW AMM DMC B787-A-G79-21-01-00A-520A-A AND -720A-A AND OPERATIONAL TEST WAS PERFORMED IAW AMM B787-A-G71-00-00-09A-950A-A, ALL CORRECT.
