## Discrepancy

DURING ROUTINE MAINTENANCE, CHANGING RIGHT COWL FLAP CABLE, THE HEATER'S FUEL LINE CONTACTED THE NON-INSULATED TERMINAL BOARD'S STUD AT RIGHT WING STA 27.125.  PLACING MASTER SWITCH IN ON POSITION PROVIDED A SHORT CIRCUIT AND FIRE.  THE TERMINAL BOARD'S STUDS NEED TO BE INSULATED FROM FUEL AND OIL LINES IN IMMEDIATE AREA.
