Title 14 of the Code of Federal Regulations
This database is a repository of certain Code of Federal Regulations (CFRs) and Special Federal Aviation Regulations (SFARs) from 14 CFR in their current version as well as historical versions. The current CFRs and SFARs refer to those documents that are in effect today. The historical CFRs and SFARs represent each CFR Part section from the original (since re-codification from the Civil Air Regulations). The CFR includes the active document as a result of the most recent amendment. When looking at the historical CFRs and SFARs, the checkmark indicates the CFR Part section or SFAR Part that is most current.

Preamble material can be found in the "CFR Final Rules" database.

PLEASE NOTE: at the bottom of each document is a “Document History” section that gives you links to other related Rulemaking documents.
