## Discrepancy

(CAN) A WIRE BUNDLE BEHIND THE RT INSTRUMENT PANEL HAD CHAFED ON A SCREW SECURING A FACTORY INSTALLED BLANKING PLATE.  THE NUT APPEARS TO HAVE BECOME LODGED IN THE CASING SECURING THE WIRE BUNDLE ALLOWING THE SCREW TO CHAFE THROUGH THE INSULATION ON TWO WIRES. THE SCREW WAS OBSERVED TO FLASH WHITE AND THE INSTRUMENT PANEL SHOWS SIGNS OF HEAT DAMAGE AROUND THE SCREW HOLE.
