Analysis

The student plt was on his 1st solo x-country flt. Shortly after leveling on the 2nd leg of the flt, the eng lost power & would not restart. As the student was maneuvering to land in a field, the acft's left wing struck a treetop, then the acft crashed to the ground. An investigation revealed that the fuel system was contaminated with debris from the deteriorating carburetor accelerator pump. A fuel sample was taken for an analysis, which revealed the fuel was a mixture of avgas & automotive gasoline.
