NTSB Narrative Summary Released at Completion of Accident

The pilot stated that after refueling the airplane embarked and tried to start the airplane, and said that it would not start. He said he turned off the magneto switch, set the brakes, got out the airplane, and tried starting it by hand several times, but it would not start. After a brief distraction he said that when he again moved the propeller, all of a sudden the engine started operating immediately. He said the airplane moved forward and was heading toward the fuel tank, so he ran after it and grabbed the left strut to keep it from hitting the tank. He said the airplane proceeded between the fuel tank and the credit card machine, knocking him to the ground, and continued on, impacted two parked airplanes and two chain linked fences before stopping.

NTSB Probable Cause Narrative

The pilot's failure to set the parking brake and his improper starting procedure which resulted in an unattended aircraft running away after hand starting the engine and the airplane colliding with parked airplanes, incurring substantial damage.
