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

WITNESSES STATED THE ENG FAILED ABRUPTLY AS THE ACFT MADE A RIGHT TURN AFTER TAKEOFF. THE ENG WAS PLACED ON A TEST STAND AFTER THE ACCIDENT AND OPERATED TO FULL POWER WITH NO EVIDENCE OF FAILURE OR MALFUNCTION. UNCONTAMINATED FUEL WAS FOUND IN THE AIRFRAME AND ENG FUEL SYSTEM AFTER THE ACCIDENT. THE ENG IGNITION SWITCHES WERE DESTROYED IN THE ACCIDENT AND THE POSITION OF THESE SWITCHES COULD NOT BE DETERMINED. WITNESSES TO THE ACCIDENT OBSERVED THE ENG OPERATE ON THE TEST STAND AND WHEN THE IGNITION SWITCHES WERE TURNED OFF THE ENG FAILED ABRUPTLY. THEY IDENTIFIED THIS FAILURE MODE AS SIMILAR TO THE INFLIGHT FAILURE OF THE ENG. THE OTHER OWNER OF THE ACFT STATED HE HAD INADVERTENTLY TURNED OFF THE IGNITION SWITCHES A FEW YEARS BEFORE WHEN HE BUMPED THEM WHILE CLOSING THE AIR VENT. HE STATED THE POINT IN THIS FLIGHT THAT THE ENG FAILED WOULD HAVE BEEN THE POINT THE PLT WOULD HAVE CLOSED THE AIR VENT.
