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

DURING A DAY CROSS-COUNTRY FLIGHT THE AIRPLANE EXPERIENCED A COMPLETE LOSS OF LEFT ENGINE POWER. NORMAL RESTART PROCEDURES WHICH INCLUDED A SELECTION OF THE CROSS-FEED POSITION FAILED TO RESTORE POWER TO THE LEFT ENGINE. THE PILOT DIVERTED TO AN EN ROUTE AIRPORT FOR A SINGLE ENGINE APPROACH AND LANDING. AS THE PILOT INITIATED A SINGLE ENGINE GO-AROUND, A COMPLETE POWER LOSS OCCURRED TO THE RIGHT ENGINE. THE AIRPLANE IMPACTED TREES AND TERRAIN OFF THE DEPARTURE END OF THE RUNWAY. INVESTIGATION REVEALED A BROKEN FUEL FITTING ON THE LEFT FUEL SELECTOR UNIT AND WORN THREADS ON A FUEL FITTING ON THE RIGHT ENGINE. THIS RESULTED IN THE FUEL STARVATION POWER LOSS TO BOTH ENGINES.

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

FUEL STARVATION INDUCED POWER LOSS ON FIRST THE LEFT ENGINE DUE TO A FAILED FUEL FITTING AND THEN THE RIGHT ENGINE DUE TO A WORN FUEL FITTING. A FACTOR WAS THE LACK OF SUITABLE TERRAIN FOR THE FORCED LANDING.
