What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot/owner was intending to make a short flight from OG20 to 4S9 due to the sale of the aircraft but after starting the engine a witness did not observe any activity from the pilot. The witness approached the airplane, opened the pilots door, and shook the pilot. Shaking the pilot appeared to cause a release of the toe brakes. The airplane taxied into a barbed wire fence before the witness was able to shut down the engine. First responders pronounced the pilot deceased due to an apparent heart attack. The airplane sustained minor damage to the leading edges of both wings.
