NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

WHILE ON INITIAL CLIMB, THE LEFT ENGINE QUIT. THE PILOT MADE A GEAR UP LANDING IN A FIELD, COMING TO REST ONE-HALF MILE FROM THE END OF THE RUNWAY. THE INVESTIGATION SHOWED THAT THE LEFT PROPELLER HAD NOT BEEN FEATHERED, BUT THE RIGHT PROPELLER SHOWED EVIDENCE OF BEING FEATHERED PRIOR TO IMPACT. AN ENGINE RUN OF THE LEFT ENGINE SHOWED THE UNMETERED FUEL PRESSURE WAS SET TOO HIGH AT IDLE, RESULTING IN ROUGH RUNNING AND ENGINE STOPPAGE. EVIDENCE FROM THE AIRCRAFT LEFT ENGINE LOGBOOK INDICATED A HISTORY OF HARD STARTING, MIXTURE RELATED PROBLEMS AND ROUGH RUNNING. THE OPERATOR HAD KNOWLEDGE OF THESE FAULTS. HE TOLD THE PILOT TO START THE LEFT ENGINE WITH THE MIXTURE LEVER RETARTED TO NEAR IDLE CUTOFF.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

THE LOSS OF POWER ON ONE ENGINE DUE TO EXCESSIVE FUEL PRESSURE AND THE PILOT'S FEATHERING OF THE WRONG PROPELLER. FACTOR(S) WERE: OPERATION OF AIRCRAFT WITH KNOWN DEFICIENCIES BY PILOT AND OPERATOR.
