Department of Transportation Federal Aviation Administration • 14 CFR Part 23 • [Docket No. FAA-2025-0438] AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Notification of availability (NOA). SUMMARY: This document announces the availability of ASTM International (ASTM) consensus standards for use as an FAA-accepted MOC to the applicable airworthiness standards for normal category airplanes. The FAA accepts ASTM F3264-24, “Standard Specification for Normal Category Aeroplanes Certification,” with changes identified in this document. DATES: Acceptance of the means of compliance is effective on May 20, 2025. FOR FURTHER INFORMATION CONTACT: Hieu Nguyen, Federal Aviation Administration, Policy and Standards Division, AIR-600, GA, Airplanes, Rotorcraft and Emerging Aircraft Section, AIR-62B, 901 Locust Street, Room 301, Kansas City, Missouri 64106; telephone: (316) 946-4123; facsimile: (316) 946-4107; email: hieu.nguyen@faa.gov. 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 for use as a means of carrying out its policy objectives where appropriate. Consistent with the Small Airplane Revitalization Act of 2013, the FAA has been working with industry and other stakeholders through the ASTM F44 Committee on General Aviation Aircraft to develop consensus standards as a MOC in certificating small airplanes under part 23.[2] ( printed page 21393) In part 23, amendment 23-64 (81 FR 96572), published on December 30, 2016,[3] the final rule stated the FAA would publish an NOA of those consensus standards in the Federal Register when the Administrator accepts the consensus standards as an acceptable MOC. The FAA reviewed the published ASTM consensus standards developed by the ASTM F44 Committee on General Aviation Aircraft as the basis for a MOC to 65 sections of part 23, amendments 23-64 and 23-65. In some cases, the Administrator found sections of ASTM F3264-24, without changes, are accepted as a MOC for the airworthiness requirements of part 23, amendments 23-64 and 23-65. In other cases, the MOC, while based on ASTM consensus standards, include additional FAA provisions necessary to comply with the airworthiness requirements of part 23, amendments 23-64 and 23-65. 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 MOC beyond those accepted by this NOA. For example, novel airplane designs, such as unmanned airplanes or vertical takeoff and landing airplanes, may be outside the scope of this NOA, and applicants may need to propose an alternative MOC applicable to their designs accepted under § 23.…
