The NTSB's narrative final · quoted from the NTSB record
THE PILOT REPORTED A LOSS OF POWER WITH A ROUGH RUNNING ENGINE TO GROUND CONTROLLERS AND WAS GIVEN A RADAR VECTOR TOWARD A PRIVATE AIRSTRIP, BUT HE HAD INSUFFICIENT ALTITUDE TO MAKE THE RUNWAY. THE PILOT ATTEMPTED TO MAKE A NIGHT FORCED LANDING IN THE CENTER MEDIAN OF AN INTERSTATE HIGHWAY AND COLLIDED WITH POWER LINES. THE AIRCRAFT WAS EXAMINED BY AN FAA AIRWORTHINESS INSPECTOR WHO FOUND THAT THE RIGHT HAND HEAT EXCHANGER INTERNAL BAFFLING WAS DETERIORATED, ALLOWING STAINLESS STEEL MATERIAL TO LOOSEN AND EXIT OUT THE EXHAUST PIPE. IN THE SAME SECTION OF EXHAUST PIPE, A 1/4-INCH BOLT WAS INSTALLED TO RETAIN THE PIPE ON THE EXHAUST ASSEMBLY. THE BOLT WAS FOUND TO BE A NONSTANDARD INSTALLATION AND PROTRUDED 1/2 INCH INTO THE PIPE FORMING A RESTRICTION WHICH COULD COLLECT PIECES OF THE LOOSE BAFFLING MATERIAL. THE NUMBER 1 ENGINE CYLINDER WAS CRACKED ON THE EXHAUST SIDE OF THE HEAD. ALL SPARK PLUGS WERE WORN. THE RIGHT HAND MAGNETO WAS AN INCOMPATIBLE MODEL WITH THE CONTINENTAL O-200 SERIES ENGINES AND COULD NOT BE TIMED TO THE ENGINE.
