Analysis narrative
The pilot of the accident airplane had just canceled an IFR clearance and was descending in VFR conditions when he lost engine power at approximately 1200 feet agl. He declared an emergency to ATC and unsuccessfully tried to restart the engine. He gave up the restart attempts and remembers thinking; 'i've got to stop playing with it and land this thing.' he remembers turning the main fuel switch off just before the airplane struck the treetops. An after accident examination of the wreckage disclosed no mechanical defects in the airframe. No mechanical defects were noted in the engine that would have caused an inflight stoppage. Examination of the fuel system showed the main fuel switch off and the secondary auxiliary fuel tank selector switch selected to an empty auxiliary tank. Fuel was present in all of the main fuel tanks and the other auxiliary tank.
