What happened
The pilot had previously utilized automotive gasoline in the aircraft but discontinued its use due to water contamination issues. While at an airport requiring refueling, the only available fuel was automotive gasoline, so the pilot refueled the aircraft with this fuel. During a touch-and-go maneuver at Brewer Airport, the pilot experienced a partial power loss during the climbout phase at an altitude of 700 to 800 feet above ground level.
The pilot decided to land on an unopened section of a nearby highway. Just prior to touchdown, the pilot noticed a set of power lines in the flight path. The aircraft dove to pass under the power lines and struck the road surface hard enough to bounce back into the air. The pilot then lost control of the aircraft, which descended to the left side.
The aircraft flipped over upon final touchdown. No further mechanical examination or investigation details were provided in the source material.
