DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 23

[Docket No. FAA-2024-0969]


Accepted Means of Compliance (MOC); Airworthiness Standards: 
Normal Category Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of availability (NOA).

-----------------------------------------------------------------------

SUMMARY: This document announces the availability of ASTM International 
(ASTM) consensus standards for use as an FAA-accepted means of 
compliance (MOC) to the applicable airworthiness standards for normal 
category airplanes. The FAA accepts ASTM F3264-23, ``Standard 
Specification for Normal Category Aeroplanes Certification,'' with 
changes identified in this document.

DATES: Acceptance of the means of compliance is effective on May 29, 
2024.

Administration, Policy and Standards Division, GA, Airplanes, 
Rotorcraft and Emerging Aircraft Section, AIR-62B, 901 Locust Street,

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.
---------------------------------------------------------------------------

    \1\ Ref Public Law 104-113 as amended by Public Law 107-107.
---------------------------------------------------------------------------

    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\
---------------------------------------------------------------------------

    \2\ Ref Public Law 113-53.
---------------------------------------------------------------------------

    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 F3264-23, without changes, are 
accepted as an 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.
---------------------------------------------------------------------------

    \3\ See https://www.federalregister.gov/documents/2016/12/30/2016-30246/revision-of-airworthiness-standards-for-normal-utility-acrobatic-and-commuter-category-airplanes.
---------------------------------------------------------------------------

    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 alternative MOC applicable 
to their designs accepted under Sec.  23.2010.

Means of Compliance Accepted

    The FAA accepts only the revisions of the standards referenced in 
ASTM F3264-23, ``Standard Specification for Normal Category Aeroplanes 
Certification,'' as a means of compliance for part 23, amendments 23-64 
and 23-65, with the changes identified in table 1. For ease of use, 
table 2 was added to provide a side-by-side view, linking the 
applicable part 23 regulation to the ASTM F3264-23 section.

    The MOC accepted by this NOA provide one means, but not the only 
means of complying with part 23 regulatory requirements. Applicants who 
desire to use an MOC reflected by other revisions to ASTM standards not 
previously accepted may seek guidance and possible acceptance from the 
FAA for the use of those MOC on a case-by-case basis. Applicants may 
propose an alternative MOC for FAA review and possible acceptance.

[[Page 46319]]

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. In addition, ASTM issues editorial changes 
denoted by a superscript epsilon in the standard designation (e.g., 
F3235-17[egr]\1\). This epsilon indicates information was corrected, 
and it did not change the meaning or intent of a standard. Since 
reapprovals and editorial changes do not change the technical content 
of standards, then any standard FAA-accepted by this NOA that is later 
reapproved or editorially changed by ASTM, is also considered FAA-
accepted and without the need for an updated NOA.
    ASTM revises a standard to make changes to its technical content. 
Revisions are identified by a hyphen after the document number, which 
is followed by the last two numbers of the year of acceptance or of 
last revision. If the standard is revised again during the same year, 
this is indicated by adding an ``a'' for the second revision, ``b'' for 
the third revision, etc. Since revisions change the technical content, 
revisions to consensus standards serving as the basis for an MOC 
accepted by this NOA will not be automatically accepted and will 
require further FAA acceptance for the revisions to be an accepted MOC.
