According to a Federal Aviation Administration (FAA) inspector who interviewed the pilot, the pilot was attempting to change the fuel draw from the left to right fuel tank, but starved the engine of fuel in the change process due to a new modification in the fuel system.

The left wing fuel tank was compromised and right wing fuel tank contained an unknown amount of fuel.
