Analysis narrative
The pilot reported that at lift off both engines lost power. A right turn was made to avoid houses, which resulted in a collision with electrical transmission wires. The airplane then impacted the ground and slid into an out building adjacent to a residence. Examination of the airplane revealed that the fuel system contained an oily, foul smelling contaminant. The pilot said he had recently bought 300 gallons of 100ll fuel from a local fixed base operator. The fuel was transported to the pilot's fuel farm on his airfield in a tank which he uses to mix chemicals for aerial application.
