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

IMMEDIATELY AFTER TAKEOFF FROM RUNWAY 27, THE RIGHT ENGINE LOST POWER. THE PILOT DETERMINED A RETURN TO THE AIRPORT WAS NOT POSSIBLE, SO HE MADE A FORCED LANDING IN A LARGE FIELD TO THE NORTHWEST OF THE AIRPORT. AN INVESTIGATION REVEALED THAT THE EXHAUST STACK ASSEMBLY, CHAMPION PART NUMBER 4-1218, HAD CRACKED AND FAILED AT A WELD. THE P-LEADS WERE MELTED BY THE HOT EXHAUST GASES, SHORTING OUT THE MAGNETOS.
