Factual narrative
THE STUDENT PILOT, WHO WAS CARRYING A PASSENGER, MIXED AUTOMOTIVE FUEL WITH AVIATION GASOLINE. THE AUTO GAS CONTAINED WATER CAUSING THE ENGINE TO RUN INTERMITTENTLY. THE AIRPLANE TURNED OVER DURING A FORCED LANDING IN A SWAMP. POST ACCIDENT INSPECTION RVEALED THE RIGHT FUEL TANK FILLER CAP WAS MISALIGNED IN A MANNER WHICH WOULD ALLOW SIPHONING.
