99.0 PROVISION FOR ISSUANCE. Pursuant to the provisions of the Civil Aeronautics Act of 1938, as amended, authorizing the Civil Aeronautics Board to make such regulations as are necessary to execute the functions vested in it by the Act, the following regulations are prescribed for the citation of Civil Air Regulations.
99.1 DEFINITIONS.
99.10 CIVIL AIR REGULATIONS. Civil Air Regulations are those regulations issued by the Board pursuant to the Civil Aeronautics Act of 1938, as amended, and otherwise pursuant to law vesting in it the power and duty to regulate interstate and foreign air commerce and aeronautics.
99.2 MODE OF CITATION.
99.20 WORDS. The Civil Air Regulations may be cited by the words "Civil Air Regulations", or by an appropriate citation of the Code of Federal Regulations or the Federal Register.
99.21 FIGURES. The figures used in connection with Civil Air Regulations shall be cited as they appear in the left-hand margin of and opposite to each division of the Civil Air Regulations, and such citation shall include the text in each division opposite to and in connection with the figure cited. Unless limited by express language, the citation of a figure having a lesser number of digits shall include all of the figures immediately there following having a greater number of digits (if any such figures there be) together with the text in the divisions in connection with the latter, provided, that such inclusion shall stop with, and not include, any division having a larger figure but a lesser number of digits. (For example, the citation of § 99.1 includes § 99.10, but not §§ 99.20 and 99.21.) The citation of any division as indicated above does not include any there following with a figure having an equal or lesser number of digits. (For example, § 99.1 does not include § 99.2, nor does § 99.10 include § 99.2.) The citation of any Part of its figure (99) is a citation of the whole of that Part. Whenever the complete sense of a particular division requires that it be read in connection with any prior division, the citation of the former will include the latter. (No good example occurs in Part 99, but one may be found in Part 20 in connection with suspension or revocation of pilot certificated. For example, the citation of § 20.371 includes § 20.37, and that of § 20.37103 includes § 20.371 and possibly § 20.370 or § 20.37 depending upon the question under consideration.) The left-hand margin figures used in connection with Civil Air Regulations are cited as indicated above in the text of Civil Air Regulations and refer to Civil Air Regulations only. Citations to regulations other than Civil Air Regulations will be by an appropriate citation of the Code of Federal Regulations.
