14 CFR Part 23

[Docket No. FAA-2022-0217; Notice No. NOA-23-22-01]

Accepted Means of Compliance; Airworthiness Standards: Normal
Category Airplanes

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

ACTION: Issuance of accepted means of compliance.

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

SUMMARY: This document announces ASTM International (ASTM) consensus
standards for use as a means of compliance to the applicable
airworthiness standards for normal category airplanes. The FAA accepts
ASTM Designation F3264-21 as a means of compliance for applicable
airworthiness standards for normal category airplanes, with the changes
identified in Table 1 of this document. For ease of use, Table 2
provides a side-by-side view, linking applicable regulations to the
associated ASTM sections.

DATES: The FAA accepts the means of compliance effective March 11,
2022.

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

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

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

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

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

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

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

    \4\ See https://drs.faa.gov/browse.
---------------------------------------------------------------------------

    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 Sec.  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.''
---------------------------------------------------------------------------

    \5\ The means of compliance are inteded for traditional part 23
airplanes, not for novel designs. Novel designs require evaluation
and possible modification of the means of compliance.

Airplane Issues List (SAIL) here: https://www.faa.gov/aircraft/air_cert/design_approvals/small_airplanes/small_airplanes_regs/.

    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.

    \7\ The ASTM F3264-21 Section(s) provides a means of compliance
intended to be used on projects for traditional part 23 airplanes,
not for novel designs. Novel designs require evaluation and possible
modification of the means of compliance.
    \8\ The FAA does not accept the Aircraft Type Code compliance
matrix tables included in F3061/F3061M-20, F3227/F3227M-21, F3228-
17, F3229/F3229M-17, F3230-20a, F3231/F3231M-21, F3232/F3232M-20,
F3233/F3233M-21, F3234/F3234M-17, F3235-17a, F3236-17, and F3316/
F3316M-19. Applicability will be determined by the Small Airplane
Strategic Policy Section.
---------------------------------------------------------------------------

    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.,
F3235-17[epsi]1). 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.
