## Discrepancy

(CAN) DEEP GOUGES WERE FOUND ON THE BOTTOM SIDE OF BOTH THE L/H (P/N 6914060-59) AND R/H (P/N 6914060-60) WING ANTI ICE DUCTS (REFER TO IPC 30-11-00 FIG1) WHICH WAS CAUSED BY CHAFFING. THE DUCTS RUN IN VERY CLOSE PROXIMITY TO THE L/H AND R/H LIGHT BOXES WHICH HAVE ROUND HEAD RIVETS ON THE TOP SIDE OF EACH ASSEMBLY CAUSING THE PROBLEM. REPLACEMENT OF BOTH DUCTS WAS REQUIRED FOLLOWING REWORK OF THE LIGHT BOX ASSEMBLIES PRIOR TO RETURN TO SERVICE. (TC# 20190723010)
