Initial Takeoff and Abort
During the first takeoff roll, the aircraft experienced a loss of engine power, prompting the pilot to abort the takeoff. The pilot then taxied back to the runway and conducted engine run-ups. The left engine was run up three times until the 'puffing (or popping) noises' ceased, after which the pilot initiated another takeoff.
Second Takeoff and Climb
Witnesses reported hearing one or more engines sputter during the initial climb. The pilot reported losing power from the left engine within 300 feet above ground level (AGL). He executed a steep bank left turn back toward the airport, but lost control of the aircraft, which subsequently collided with the ground.
Post-Accident Examination
Following the accident, the left engine and carburetor assembly were successfully test run, indicating no anomalies in that engine. Fuel examination revealed clear, blue-colored fuel in the left engine's carburetor and gascolator, as well as in the right main fuel tank. In contrast, cloudy, green-colored sediment-laden fuel was found in the right engine's carburetor, the right engine-driven fuel pump, and the right auxiliary fuel pump. Additionally, a foreign substance was found adhered to the inside of the right engine's venturi; laboratory analysis identified the substance as polystyrene.
