THE CRASH SITE WAS LOCATED ABOUT EIGHT MILES EAST OF THE DEPARTURE AIRPORT AND WAS AT AN ELEVATION OF ABOUT 2000 FT MSL. DURING IMPACT IT STRUCK TREES AND A 20 DEGREE SLOPE WHILE ON A WESTERLY HEADING. A WITNESS STATED THAT HE HEARD AND OBSERVED THE AIRCRAFT FLY OVER HIS RESIDENCE AND THEN CRASH ABOUT ONE MINUTE LATER. HE STATED THAT WHEN THE AIRCRAFT FLEW OVER HIS POSITION, THE ENGINE WAS SPUTTERING AS IF IT WAS OUT OF GAS, AND THEN IT QUIT RUNNING ALTOGETHER. THE AIRCRAFT AND THE ENGINE WERE BADLY DEMOLISHED DURING IMPACT.
