The NTSB's narrative final · quoted from the NTSB record

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.
