§91.13 Careless or reckless operation

§91.13 Careless or reckless operation

(a) Aircraft operations for the purpose of air navigation. No person may operate an aircraft in a careless or reckless manner so as to endanger the life or property of another.

(b) Aircraft operations other than for the purpose of air navigation. No person may operate an aircraft, other than for the purpose of air navigation, on any part of the surface of an airport used by aircraft for air commerce (including areas used by those aircraft for receiving or discharging persons or cargo), in a careless or reckless manner so as to endanger the life or property of another.

This Reg is a significant one, considering that the FAA can sanction any pilot that might be performing anything considered reckless in the eyes of an investigation. So doing a runup behind another airplane and not realizing that the prop wash generated might be hitting the other plane can put you in trouble in front of an FAA inspector.
