CFR (Code of Federal Regulations)

The Code of Federal Regulations was established by the Federal Register Act of 1935 and is maintained by the National Archives and Records Administration's Office of the Federal Register. Federal agencies publish proposed and final rules in the daily Federal Register; final rules of general and permanent applicability are codified annually into the CFR. The CFR is divided into 50 Titles, each broadly corresponding to a subject area or executive department: Title 1 (General Provisions), Title 14 (Aeronautics and Space), Title 38 (Pensions, Bonuses, and Veterans' Relief), Title 49 (Transportation), and so on. Each Title is subdivided into Chapters (assigned to specific agencies), Subchapters (subject groupings within an agency), Parts (the operational unit of regulation that most users cite), Subparts (groupings within a Part), and Sections (the individual numbered regulatory provisions).

For aviation, the dominant citation lives in Title 14, which is divided across multiple agency chapters. Chapter I is the Federal Aviation Administration (FAA), Department of Transportation — the bulk of FAA operating, certification, and airworthiness regulations sit here in Subchapters covering airmen (Part 60 series), aircraft (Part 21, 23, 25, 27, 29, 33, 35), airspace and air traffic (Part 71, 73, 91, 93, 95, 97), operating requirements (Part 119, 121, 125, 129, 133, 135, 136, 137, 141, 142), and airports (Part 139, 150, 151, 157). Chapter II is the Office of the Secretary of Transportation. Chapter III is the Commercial Space Transportation regulations. Chapter V is the National Aeronautics and Space Administration (NASA) regulations.

Reading a CFR citation follows a standard format: "14 CFR 91.103" means Title 14, CFR, Part 91, Section 103 — the preflight action requirement under the General Operating and Flight Rules. "14 CFR Part 141" refers to the entire Part on pilot schools. "14 CFR 61.65(a)(1)" drills down to a specific paragraph within Section 61.65 (the instrument rating prerequisites). The common shorthand "FAR Part 91" — Federal Aviation Regulation Part 91 — is the colloquial label for the same provisions; both "FAR" and "14 CFR" refer to the FAA's portion of Title 14, with "14 CFR" being the formally correct citation in legal contexts and "FAR" being the historical industry shorthand. The FAA has, in some recent guidance, deprecated "FAR" in favour of "14 CFR" but both remain in widespread industry use.

Aviation operators routinely encounter CFR citations beyond Title 14. TSA security regulations live at 49 CFR Part 1500-series (specifically 49 CFR 1544, 1546, 1552, 1554, 1572 for various aviation security topics). DOT economic regulations affecting air carriers live at 14 CFR Chapter II and 49 CFR Part 200-series. NTSB accident investigation procedures live at 49 CFR Part 800-series. VA education benefits for veterans pursuing flight training are codified at 38 CFR Part 21 (with the statutory authority in 38 U.S. Code Chapter 30, 31, 33, 35 and 10 U.S. Code Chapter 1606). Operators that conflate these Titles — treating "the regulations" as a single Title 14 body — frequently miss the parallel obligations imposed by 38 CFR (for VA-approved schools), 49 CFR (for TSA-vetted training of foreign nationals under FTSP), and Title 26 (Internal Revenue Code, for fuel tax and aircraft depreciation matters).

The CFR is updated annually on a rolling schedule, with different Titles updated at different calendar times: Title 14 is published with a January 1 effective date. The annual print version of Title 14 reflects the regulations as of that effective date. For current effective regulations between annual publications, the daily Federal Register reflects newly issued or amended rules, and the eCFR (electronic CFR) at ecfr.gov provides a continuously updated unofficial compilation that most operators rely on for day-to-day reference. The eCFR includes redline change tracking and historical versions, supporting compliance work that needs to verify what the regulation said on a specific date.

For a flight school's chief instructor, director of training, or compliance manager, fluency in reading and citing CFR provisions is a foundational professional skill. The school's operations manual, training course outlines, and standard operating procedures cite CFR provisions extensively, and the assigned POI references CFR provisions during surveillance and approval discussions. Schools whose senior staff cannot quickly locate the cited regulation, distinguish a Section from a Subpart, or recognise the difference between regulatory text (binding) and the associated Advisory Circular (non-binding guidance) typically struggle to negotiate regulatory questions effectively with their FSDO.

The practical research workflow centres on the eCFR. When the POI cites a provision the school had not previously focused on, the chief instructor pulls the provision on eCFR, examines the surrounding Subpart context, follows any cross-references to other CFR Parts, and identifies the related Advisory Circular guidance that describes the FAA-acceptable means of compliance. Schools that build this workflow into their quality system — with version-controlled snapshots of the operations manual against the CFR effective dates, internal training on CFR citation conventions, and structured review of Federal Register notices for proposed changes — typically achieve more predictable compliance outcomes than schools that treat regulatory reference as ad hoc.

Aviatize's compliance and auditing module supports CFR-anchored documentation across the school's regulatory artefacts. Operations manual sections, training course outlines, instructor handbooks, and standard operating procedures can cite specific CFR provisions with stored cross-references; when the cited CFR Part is amended, affected internal documents are flagged for review and the review workflow captures the school's impact assessment and any required document revisions. The platform retains historical versions of the school's internal documentation aligned to CFR effective dates, supporting the school's ability to demonstrate that operations on any past date were governed by the then-current regulatory framework and the corresponding internal procedures.

The training management module supports CFR-aligned syllabus design — each lesson plan, knowledge check, and skill test item can be tagged with the underlying CFR provision (e.g. 14 CFR 61.65 for instrument rating prerequisites, 14 CFR 91.103 for preflight action). When the FAA publishes an amendment to a relevant provision, the platform identifies the affected syllabus elements and supports the chief instructor's review-and-update workflow before the amendment takes effect.
