Q. Federal Aviation Regulations (FAR) Preambles
Federal Aviation Regulations (FAR) Preambles
According to the FAA Law Librarian, the best way to find the FAR preambles (there isn't one easy source for this) is to search the Federal Register for the first publication of that particular regulation. Of course, different parts are made up of individual sections which may have been propagated at different times. For instance, FAR 198.1 or 198.40 may have different histories. If the regulation was propagated since July of 1980, the Federal Register search can be done online, in Lexis or Westlaw, which your librarian may have access to. HeinOnline (which DOT employees have access to) has electronic access back to 1980.
The key is to follow the trail back through the Federal Register, keeping an eye out for footnotes with earlier FR cites. If the regulations started before July 1980, you would have to find the Federal Register in print or on microfilm/fiche or via HeinOnline. Your library may also have that, or if not, try another library in your area.
