Narrative

N64UV SUSTAINED SUBSTANTIAL DAMAGE DURING AN EMERGENCY LANDING, IN A 
   FIELD NEAR THE GRAND FORKS INTERNATIONAL AIRPORT, NORTH DAKOTA. DURING 
   FINAL APPROACH TO LANDING, THE AIRCRAFT ENGINE SUDDENLY STOPPED. THE 
   INSTRUCTOR TOOK OVER THE CONTROLS. HE SAID THE ENGINE DID NOT RESTART 
   AND HE WAS FORCED TO LAND ON AN UNSUITABLE LANDING SURFACE. DURING THE 
   LANDING ROLL THE AIRCRAFT NOSED OVER. INSPECTION OF THE ENGINE 
   INDICATED THAT THE POWER LOSS WAS DUE TO VAPOR LOCK IN THE INLET FUEL 
   LINE TO THE ELECTRIC BOOST PUMP. SUBSEQUENT ENGINE TEST RUN WAS 
   SUCCESSFUL.

   Occurrence #: 2  180 FORCED LANDING
   Phase of Operation: 552 DESCENT - EMERGENCY

           Findings
           Subject - Modifier - Personnel Cause/Factor


   Occurrence #: 3  300 NOSE OVER
   Phase of Operation: 572 LANDING - ROLL

           Findings

Probable Cause

AN OVER TEMPERATURE OF THE INLET FUEL LINE RESULTING IN FUELSTARVATION 
   (VAPOR LOCK) IN THE FUEL INJECTION SYSTEM.  A FACTOR IN THE ACCIDENT 
   WAS THE LACK OF A SUITABLE LANDING AREA.
