What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
According to privacy data omitted statement, he attempted to start his aircraft and the battery was too weak. He then hooked up the jumper box in order to charge the battery enough to start the engine. After getting the engine started, he exited the aircraft while it was still running to disconnect the jumper box. As he disconnected the box, the aircraft began to roll away. As he chased the aircraft he fell but got up and continued pursuit. He caught up and grabbed the aircraft prior to it striking the hanger, but could not stop the aircraft from rolling. At that time the aircraft rolled into the hanger door propeller first tearing a large hole in the door.
