There shall be no “hand propping” or starting an aircraft unless there is a licensed pilot or mechanic at the controls. Airplanes must be chocked or adequately braked for starting. If no occupant is at the controls of a propping aircraft, the aircraft must be securely tied before starting. No pilot will, at any time, leave the airplane when the engine is running, unless there is another competent operator at the controls or the aircraft is secured.
