WHILE CRUISING AT 42,000 FEET, THE PILOT ATTEMPTED TO ADUST HIS MAP LIGHT WHEN THE CIRCUIT BREAKER POPPED. WHEN THE COPILOT RESET THE BREAKER A FIRE IGNITED AT THE OXYGEN PANEL. THE BLOWTORCH EFFECT CAUSED EXTENSIVE DAMAGE TO THE LEFT INTERIOR AT THE PILOT'S STATION. TWO PASSENGERS WERE HOSPITALIZED FOR SMOKE INHALATION.

SUBSEQUENT TO THE MISHAP, LEARJET DEVELOPED A PROTECTION KIT TO PREVENT CONTACT BETWEEN THE OXYGEN LINES AND ELECTRICAL COMPONENTS.

ELECTRICAL ARCING WHICH RESULTED FROM A SHORT IN THE PILOT'S MAP LIGHT CIRCUIT; A CHAFTED WIRE CONTACTED THE OXYGEN SUPPLY LINE AT THE OXYGEN CONTROL PANEL IN THE COCKPIT. A FACTOR IN THE ACCIDENT WAS THE INADEQUATE DESIGN OF THE OXYGEN PANEL PLUMBING AND ELECTRICAL WIRING FOR THE PILOT'S MAP LIGHT WHICH ALLOWED CONTACT BETWEEN THE TWO SYSTEMS.
