## Analysis

DURING A DEADHEADING FLIGHT BACK TO HIS OPERATIONS BASE, THE PILOT EXPERIENCED AN INFLIGHT FIRE AND SMOKE IN THE COCKPIT. AFTER HE EXTINGUISHED THE FIRE AND EVACUATED THE SMOKE, A NORMAL LANDING WAS MADE. EXAMINATION OF THE AIRCRAFT REVEALED THAT THE ALTERNATOR BONDING WIRE HAD BROKEN OFF THE TERMINAL AND ONE LEAD TO THE VOLTAGE REGULATOR WAS BROKEN OFF. AN FAA INSPECTORS' SURVEILLANCE RECORD STATED, IN PART, THAT "THE CONDITION OF THE WIRING INDICATED A LACK OF PROPER CARE AND INSPECTION."
