About this document
Title 14 of the Code of Federal Regulations (14 CFR), Aeronautics and Space, contains the binding federal aviation regulations. For pilots the most relevant parts are Part 61 (certification of pilots and instructors), Part 91 (general operating and flight rules), Part 121 (air carriers), and Part 135 (commuter and on-demand operations); maintenance personnel rely on Parts 43, 65, and 145.
Where the FAA handbooks and advisory circulars explain concepts and recommended practices, 14 CFR states the binding legal requirements. Always confirm exact numbers, limits, and currency requirements against the current regulation. The official, continuously updated text is on the eCFR.
