Analysis

The acft experienced a total power loss on takeoff & was demolished in the impact sequence & post crash fire. According to several interviewees the pilot had performed extensive non-stc'd modifications to the acft including the fuel system. An 'automotive performance computer' requiring a fuel flow transducer which, according to the manufacturer, would not work on a gravity fed system. A fuel pump found in the wreckage was determined to be a fuel transfer dump designed to reduce the output flow to zero at its maximum output line pressure of 4.5 PSI. The transducer would have reduced the fuel output flow to a 'trickle'.
