SUPPLEMENTARY INFORMATION: Background Under the provisions of the National Technology Transfer and Advancement Act of 1995 [1]
                    
                     and Office of Management and Budget (OMB) Circular A-119, “Federal Participation in the Development and Use of Voluntary Consensus Standards and in Conformity Assessment Activities,” effective January 27, 2016, the FAA participates in the development of consensus standards and uses consensus standards as a means of carrying out its policy objectives where appropriate. Consistent with the Small Airplane Revitalization Act of 2013,[2]
                    
                     the FAA has been working with industry and other stakeholders through the ASTM International (ASTM) F44 Committee on General Aviation Aircraft to develop consensus standards as a means of compliance in certificating small airplanes under title 14, Code of Federal Regulations (14 CFR), part 23. In part 23, amendment 23-64 [3]
                    
                     (81 FR 96572, published on December 30, 2016), the final rule described the FAA would publish those consensus standards in the 
                    **Federal Register**
                    , when the Administrator accepts the consensus standards as an acceptable means of compliance. Additionally, the FAA published Advisory Circular (AC) 23.2010-1,[4]
                    
                     dated March 27, 2017, titled “FAA Accepted Means of Compliance Process for 14 CFR part 23”. In paragraph 5.5, the AC also describes that a notice will be published when the Administrator accepts a standard. The means of compliance accepted by this document is one means, but not the only means of complying with part 23 regulatory requirements. The FAA reviewed the published ASTM consensus standards developed by ASTM Committee F44 as the basis for means of compliance to 65 sections of part 23, amendment 23-64. In some cases, the Administrator found sections of the ASTM Standard Designation F3264-21, titled “Standard Specification for Normal Category Aeroplanes Certification,” without changes, accepted as means of compliance with the airworthiness requirements of amendment 23-64, and within the scope and applicability of the consensus standards. In other cases, the means of compliance, while based on ASTM consensus standards, include additional FAA provisions necessary to comply with the airworthiness requirements of amendment 23-64. Applicants who desire to use means of compliance reflected by other revisions to ASTM standards not previously accepted, may seek guidance and possible acceptance from the FAA for the use of those means of compliance on a case-by-case basis. Applicants may also propose alternative means of compliance for FAA review and possible acceptance. Part 23, amendment 23-64, established airworthiness requirements based on the safety requirements outlined in amendment 23-63, except in areas that address loss of control and icing, where the FAA increased the safety level. Depending on the details of a design, the applicant may require use of a different means of compliance beyond those accepted by this document. For example, novel airplane designs, such as unmanned airplanes or vertical takeoff and landing airplanes, may be outside the scope of this document, and applicants may need to propose alternative means of compliance applicable to their designs accepted under § 23.2010. Means of Compliance Accepted This document accepts only the revisions of the standards referenced in ASTM International Standard Designation (ASTM) F3264-21, “Standard Specification for Normal Category Aeroplanes Certification.” *Table 1.*
                     The FAA accepts ASTM F3264-21 as a means of compliance for part 23, amendment 23-64, with the changes identified. *Table 2.*
                     For ease of use, Table 2 provides a side-by-side view, linking the applicable part 23 regulations to the ASTM F3264-21 sections. The ASTM F3264-21 sections must incorporate the changes required for FAA acceptance from Table 1. Table 1—Part 23 Accepted Means of Compliance Based on ASTM Consensus Standards

 Editorial, Reapproval, Revision or Withdrawal ASTM policy is that a consensus standard should be reviewed in its entirety by the responsible subcommittee and must be balloted for reapproval, revision, or withdrawal, within five years of its last approval date. When an ASTM standard is reapproved, that reapproval is denoted by the year in parentheses (
                    *e.g.,*
                     F2427-05a(2013)). This date indicates the completion of a review cycle with no technical changes made to the standard. ASTM issues editorial changes denoted by a superscript epsilon in the standard designation (
                    *e.g.,*
                     F3235-17ε1). This indicates information was corrected, and it did not change the meaning or intent of a standard. Any means of compliance accepted by this document, that is based on a standard later reapproved or editorially changed, is also considered accepted and without the need for a notice in the 
                    **Federal Register**
                    . ASTM revises a standard to make changes to its technical content. Revisions to consensus standards serving as the basis for means of compliance accepted by this document, will not be automatically accepted, and will require further FAA acceptance in order for the revisions to be an accepted means of compliance.
