## Discrepancy

DURING TRANSIT CHECK,  DETECTED A HYDRAULIC LEAK IN THE LEFT MAIN LANDING GEAR RETRACT ACTUATOR.  MAINTENANCE PERFORM A PRESSURIZATION OF THE SYSTEM TO VERIFY THE LEAKS, DID NOT CONFIRM THE HYDRAULIC LEAK.  AS A PRECAUTION, THE LEFT MAIN LANDING GEAR RETRACT ACTUATOR WAS REPLACED IAW AMM DMC-B787-A-32-32-01-00A-520A-A AND DMC-B787-A-32-32-01-00A-720A-A, TESTED CORRECT.
