Probable cause
An over temperature of the inlet fuel line resulting in fuel starvation (vapor lock) in the fuel injection system. A factor in the accident was the lack of a suitable landing area.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
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 poer loss was due to vapor lock in the inlet fuel line to the electric boost pump. Subsequent engine test run was successful.
