## Discrepancy

EXTERNAL POWER POSITIVE CABLE BENT UPWARDS AT TERMINAL STUD PARTIALLY EXPOSING CABLE FROM UNDER PROTECTIVE TERMINAL BOOT AT SWAGED TERMINAL END.  CABIN AIR VALVE HOUSING PN 145-42122 SA11 CONTACTED EXPOSED AREA CREATING A DIRECT SHORT THROUGH THE CABIN AIR CONTROL CABLE CONNECTED TO THE RT SIDE LOWER INSTRUMENT PANEL. CONTROL CABLE SUBSEQUENTLY HEATED UP THE LUBRICANTS INSIDE THE CABLE AND A SMALL 1-2 SQ/IN SECTION OF THE RT INTERIOR PANEL CREATING SMOKE IN THE CABIN.  PILOT SHUTOFF MASTER SWITCH, CLEARED THE SMOKE AND LANDED UNEVENTFULLY.  SUGGEST ADDITIONAL CLAMPING FOR EXTERNAL POWER CABLE AND/OR AN ADDITIONAL INSULATING BARRIER. ADDITIONAL SUPPORT RECOMMENDED ON CABIN AIR VALVE ASSY, AS BY DESIGN THESE COMPONENTS ARE IN VERY CLOSE PROXIMITY TO EACH OTHER.
