## Analysis

THE FLIGHT EXPERIENCED IN-FLIGHT FIRE RESULTING FROM AN ELECTRICAL SHORT IN AN AUXILIARY CIRCUIT BREAKER PANEL INSTALLED AFTER AIRCRAFT MANUFACTURE. THE SHORT RESULTED FROM THE USE OF A MOUNTING BRACKET THAT CHAFED AGAINST THE INPUT WIRES. THE FLIGHTCREW EXTINGUISHED THE FIRE BUT FAILED TO COMPLETE THE PRESCRIBED EMERGENCY PROCEDURES TO ISOLATE THE FAULTY CIRCUITS AND RESTORE POWER TO OTHER CIRCUITS. THIS RESULTED IN A LANDING WITHOUT STABILIZER TRIM, WING FLAP DEPLOYMENT OR BRAKE ANTI-SKID PROTECTION. THE PILOT INTENTIONALLY SWERVED THE AIRCRAFT OFF THE RUNWAY PAVEMENT TO AVOID OVERSHOOTING THE 8,800 FOOT RUNWAY.
