What was found
(CAN) DURING FLIGHT, SOME 250 NM AFTER TAKEOFF, HOT CUP WAS INSERTED INTO ITS SOCKET. WHEN PLUG TERMINAL PINS TOUCHED THE POWER RECEPTACLE THEY WERE ALSO IN CONTACT WITH THE ALUMINIUM PANEL WHICH ALSO HAS A METAL HONEYCOMB STRUCTURE. A SHORT CIRCUIT TO GROUND THROUGH THE PANEL CAUSED A FLASH AND CREATED SMOKE AND FUMES. IT DESTROYED THE CUP, AC PDE AND TRIP SETTING MODULE AND DAMAGED THE PANEL AND ITS MOUNTING BRACKET.
