ACCORDING TO THE PILOT, THE ENGINE STOPPED RUNNING DURING CRUISE FLIGHT. FUEL WAS AVAILABLE, BUT THE ENGINE COULD NOT BE RESTARTED. DURING AN EMERGENCY WHEELS-UP LANDING ON ROUGH TERRAIN, THE AIRPLANE SLID INTO A TREE. EXAMINATION OF THE FUEL SYSTEM REVEALED THAT THE FUEL PRESSURE REGULATOR WAS ADJUSTED TO A MINIMUM PRESSURE SETTING. ABOUT 4 PSI OF FUEL PRESSURE WAS AVAILABLE; A MINIMUM OF 10 PSI WAS NEEDED FOR THE PRESSURE CARBURETOR TO OPERATE. WITH THE LINE FROM THE ENGINE DRIVEN FUEL PUMP TO THE FUEL PRESSURE REGULATOR BLOCKED (FOR A TEST), THE FUEL PRESSURE WOULD READ IN EXCESS OF 15 PSI. NO REASON WAS FOUND FOR THE IMPROPER ADJUSTMENT.
Probable Cause: IMPROPER ADJUSTMENT OF THE FUEL PRESSURE REGULATOR WHICH PRODUCED AN INADEQUATE FUEL FLOW AND SUBSEQUENT FUEL STARVATION. FACTORS RELATED TO THE ACCIDENT WERE: THE ROUGH TERRAIN AND TREES IN THE EMERGENCY LANDING AREA.
