The NTSB's narrative final · quoted from the NTSB record
THE PILOT REPORTED THAT HE HAD DEPARTED RUNWAY 27, AND AT 400 FEET ABOVE GROUND LEVEL, JUST AFTER HE HAD RETRACTED THE LANDING GEAR, THE ENGINE HAD A LOSS OF POWER. HE REPORTED THAT HE MADE A 180 DEGREE LEFT TURN TO DOWNWIND TO RETURN TO THE RUNWAY. WHEN HE REALIZED THAT HE WAS NOT GOING TO REGAIN POWER, HE MADE ANOTHER LEFT TURN TO TRY TO LAND ON THE RUNWAY. THE AIRCRAFT IMPACTED A FIELD LEFT WING FIRST AND CAME TO REST ABOUT 20 FEET BEYOND THE INITIAL ENGINE IMPACT. THE PILOT STATED THAT THE STALL WARNING WAS SOUNDING DURING MUCH OF HIS ATTEMPT TO RETURN TO THE RUNWAY. THE RUNWAY WAS SURROUNDED BY FLAT PLOWED FARM FIELDS. AN INSPECTION OF THE AIRCRAFT AND ENGINE SYSTEMS, EXCEPT FOR THE FUEL INJECTION UNIT WHICH WAS DESTROYED, REVEALED NO DEFECTS.
