## Discrepancy

DURING ANNUAL INSP, THE LEFT CROSS-FEED FUEL LINE WAS FOUND TO HAVE FUEL STAIN IN AN AREA WHERE THE FUEL LINE PASSES THROUGH THE CABIN AT THE MAIN SPAR.  THE AREA WAS ONLY VISIBLE WITH UPHOLSTERY REMOVED.  MUCH LABOR WAS REQUIRED TO REMOVE AND REPLACE THE FUEL LINE.  ON REMOVAL, SEVERAL PIN HOLES DUE TO CORROSION WERE FOUND WHEN THE LINE WAS PUT UNDER PRESSURE.
