## Discrepancy

TUBE ASSEMBLY WAS FOUND CHAFED DURING A SCHEDULED INSPECTION OF HYDRAULIC PLUMBING IN TAILCONE.  THE TUBE ASSEMBLY WAS REPLACED WITH A NEW TUBE ASSEMBLY.  AIRCRAFT HAS HAD AFFECTED TUBE ASSEMBLY PREVIOUSLY REPLACED BY COMPLIANCE WITH SB 25-336.  TUBE ASSEMBLYS IN TAILCONE CAN BE DIFFICULT TO INSPECT UNLESS VIEWED PROPERLY.  A THROUGH VISUAL INSPECTION AT SCHEDULED INSPECTIONS AND WHEN THREE-WAY VALVES ARE REMOVED IS RECOMMENDED.
