THE PILOT-IN-COMMAND'S FAILURE TO FOLLOW THE PUBLISHED EMERGENCY PROCEDURES. FACTORS WERE ENGINE FIRE WARNING SYSTEM ACTIVATING FOR UNDETERMINED REASONS, AND THE RESULTANT AC POWER LOSS WHEN THAT ENGINE WAS SECURED. THE LACK OF RECENT EXPEREINCE IN TYPE AIRCRAFT AND THE LOSS OF CONTROL DURING THE LANDING ROLL.

Read the full NTSB narrative

THE CREW AND PASSENGERS WERE TESTING ELECTRONIC EQUIPMENT WHEN THE PILOTS RECIEVED A LEFT FIRE WARNING LIGHT AND BELL. THE PILOT SECURED THE LEFT ENGINE AND LANDED UNDER SINGLE ENGINE CONDITIONS. DURING THE LANDING THE PILOT LOST CONTROL OF THE AIRCRAFT DUE TO A LACK OF NOSE WHEEL STEERING. THE STEERING WAS LOST BECAUSE THE LEFT ENGINE WAS SHUT DOWN. THIS ENGINE ALSO DEVELOPS THE REQUIRED AC POWER. UNDER EMERGENCY CONDITIONS THE NOSE STEERING IS OPERATED UNDER DC POWER AND THIS IS ACTIVATED BY THE CREW. THE CREW DID NOT ACTIVATE THE DC POWER SWITCH.
