Analysis

Aircraft lost power during takeoff. Pilot tried to turn back to airport in a left bank described as 60 to 90 degrees. Aircraft stalled and crashed about 1300 feet east of takeoff point. During the investigation the fuel pump was placed on a flow bench & on the initial test would not pump fuel. The vapor separator tower coverplate was removed & a foreign object was observed in the orifice of the vapor ejector. There were particles of a black substance floating in the separator tower. When the fuel was poured onto a white towel the particles discolored the towel as graphite might do. After the vapor tower & ejector orifice were cleaned, the pump operated normally.
