The NTSB's narrative final · quoted from the NTSB record
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.
