What was found
DURING POSTFLIGHT INSPECTION, FOUND AFT CABIN VIP SEAT SWITCHING PANEL ASSY, LOCATED ON DRINK RAIL, TO BE INOPERATIVE AND COULD SMELL ODOR CAUSED BY AN INTERNAL SHORT TO THE SWITCHING PANEL ASSY. THE SWITCHING PANEL IS NOT THERMALLY PROTECTED AND THE ELECTRICAL SHORT CONTINUED UNTIL POWER WAS REMOVED. THE SWITCH PANEL ASSY WAS "HOT" TO TOUCH, HAD TO WAIT FOR IT TO COOL DOWN BEFORE IT COULD BE REMOVED FOR REPAIR. UPON FURTHER INVESTIGATION, FOUND THAT THE SHORT WAS CAUSED BY AN INTERNAL SCREW THAT HAD CHAFED THRU THE POWER HARNESS. THIS COULD HAVE BEEN PREVENTED HAD THE POWER HARNESS BEEN PROTECTED BY APPLYING ANTI-CHAFE MATERIAL OVER SCREW HEADS. UNIT WAS SENT AND WAS REPAIRED UNDER WO 327-9073 ON MARCH 18, 2015.
