A pilot who earlier refueled with automotive gasoline on a highway added aviation fuel at an airport, then experienced engine power loss during takeoff, leading to a forced landing that tore off a wing and destroyed the aircraft by fire.

Incident Overview

Earlier in the day, a pilot landed on a highway after the aircraft ran low on fuel. He purchased 15 gallons of automobile fuel and added it to the aircraft's fuel tanks. Subsequently, he took off from the highway and flew to an airport, where he added an additional 20 gallons of 100LL aviation fuel.

Takeoff and Power Loss

During a takeoff from the airport, the engine lost power at approximately 150 to 200 feet above ground level. A witness reported that the aircraft used the entire 3,100-foot runway during the takeoff roll.

Forced Landing and Post-Crash Fire

Following the power loss, the pilot performed a forced landing. During the landing, one wing was torn off and the aircraft burned.

Investigation Findings

Water was found in the carburetor bowl. However, the fuel lines were damaged, and it is possible that water entered the carburetor bowl during firefighting operations.
