## Discrepancy

FOUND BOTH LT AND RT MLG UPLOCK HYD LINES P/N 5927120-10 AND 5927120-11 WITH TOOLING MARKS. THESE MARKS EXCEEDED THE MIN WALL THICKNESS AND HAD DENTED THE LINE. THE TOOLING MARKS ARE CAUSED BY YEARS OF REMOVING AN INSPECTION PANEL DIRECTLY BEHIND THE LINE. MORE CAUTION SHOULD BE TAKEN DURING PANEL REMOVAL. MFG COULD NOT GIVE A LEAD TIME OR PRICE FOR PURCHASING NEW REPLACEMENT PARTS BUT WILL CHARGE YOU $600 FOR SPEC'S OF THE ASSEMBLY.
