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.
---------------------------------------------------------------------------
[[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.
---------------------------------------------------------------------------
\3\ See <a href="https://www.federalregister.gov/documents/2016/12/30/2016-30246/revision-of-airworthiness-standards-for-normal-utility-acrobatic-and-commuter-category-airplanes">https://www.federalregister.gov/documents/2016/12/30/2016-30246/revision-of-airworthiness-standards-for-normal-utility-acrobatic-and-commuter-category-airplanes</a>.
---------------------------------------------------------------------------
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 Sec. 23.2010.
Means of Compliance Accepted
The FAA accepts only the revisions of the standards referenced in
ASTM F3264-24, ``Standard Specification for Normal Category Aeroplanes
Certification,'' as a MOC 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 F3264-24 section.
This is a guidance document. Its content is not legally binding in
its own right and will not be relied upon by the Department as a
separate basis for affirmative enforcement action or other
administrative penalty. Conformity with the guidance document is
voluntary only, and nonconformity will not affect rights and
obligations under existing statutes and regulations.
---------------------------------------------------------------------------
\4\ The MOC are intended for traditional part 23 airplanes, not
for novel designs. Novel designs require evaluation and possible
modification of the MOC.
\5\ Wherever ``shall'' is used within a standard, replace with
``must.''

\7\ The ASTM F3264-24 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\ Changes required for FAA acceptance and additional information per
table 1 still apply to table 2. The FAA does not accept the Aircraft
Type Code compliance matrix tables included in F3228-21, F3229/F3229M-
17, F3230-21a, F3231/F3231M-23, F3233/F3233M-21, F3234/F3234M-21,
F3235-22, F3236-21a, and F3316/F3316M-19. The tables defining
applicability found in F3061/F3061M-22b sections 4, 10, 13, and 17 are
not accepted. Applicability will be determined by the Policy and
Standards Division.
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 a 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.
Editorial, Reapproval, Revision, or Withdrawal
ASTM policy states 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[epsi]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, and so on for each revision. Since revisions change
the technical content, revisions to consensus standards that are the
basis for a MOC accepted by this NOA will not be automatically
accepted, and will require further FAA acceptance for the revisions to
be an accepted MOC.
