## Discrepancy

WHILE BOTH MLG TRUNNION FAIRINGS WERE REMOVED FOR OTHER MAINTENANCE, TRUNNIONS AND BRAKE LINES WERE CLEANED AND INSPECTED.  OPERATOR DISCOVERED RT BRAKE LINE CHAFED THROUGH AND WEEPING HYDRAULIC FLUID.  CHAFED POINT IN LINE WAS A BEAM FLANGE ON TRUNNION WHICH SUPPORTS COPILOT'S STEP.  A HOSE (WHICH SHOULD BE POSITIONED MIDWAY ALONG BRAKE LINE TO PREVENT CONTACT WITH THE STEP STRUCTURE) WAS FOUND AT LOWER END OF BRAKE LINE.  HOSE SEGMENT HAD EVIDENTLY MIGRATED DOWN THE LINE AS RESULT OF VIBRATION OR ACCUMULATED LANDINGS.  LOGBOOK ENTRIES SUGGEST THIS HOSE COMPONENT WAS PART OF ORIGINAL INSTALLATION.
