This document announces the availability of means of compliance to the applicable airworthiness standards for normal category airplanes. The Administrator finds these means of compliance to be an acceptable means, but not the only means, of showing compliance to the applicable SUMMARY: PO 00000 Frm 00024 Fmt 4700 Sfmt 4700 airworthiness standards for normal category airplanes and that they provide an appropriate level of safety. DATES: Effective September 22, 2020. FOR FURTHER INFORMATION CONTACT: Andy Supinie, Federal Aviation Administration, Policy and Innovation Division, Small Airplane Standards Branch, AIR–690, 901 Locust Street, Room 301, Kansas City, Missouri 64106; telephone (316) 946–4150; facsimile: (316) 946–4107; email: andrew.supinie@ 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 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 lop consensus standards for use as a means of compliance in certificating small airplanes under Title 14, Code of Federal Regulations (14 CFR) part 23. In promulgating part 23, amendment 23–64 3 (81 FR 96572, December 30, 2016), the FAA explained that if it determined such consensus standards were acceptable means of compliance to part 23, it would publish a notice of availability of those consensus standards in the Federal Register. Pursuant to FAA Advisory Circular 23.2010–1,4 ‘‘FAA Accepted Means of Compliance Process for 14 CFR part 23,’’ section 3.1.1, this notice serves as a formal acceptance by the Administrator of means of compliance based on consensus standards developed by ASTM. The means of compliance accepted by this notice are one means, but not the only means of complying with part 23 regulatory requirements. The FAA reviewed 35 published ASTM consensus standards, developed by ASTM Committee F44, as the basis for means of compliance to 65 sections 1 Ref Public Law 104–113 as amended by Public Law 107–107. 2 Ref Public Law 113–53. 3 See https://www.federalregister.gov/documents/ 2016/12/30/2016-30246/revision-of-airworthinessstandards-for-normal-utility-acrobatic-andcommuter-category-airplanes. 4 See https://rgl.faa.gov/. E:\FR\FM\22SER1.SGM 22SER1 Federal Register / Vol. 85, No. 184 / Tuesday, September 22, 2020 / Rules and Regulations of part 23, amendment 23–64. In some cases, the Administrator finds sections of ASTM Standard F3264–19, ‘‘Standard Specification for Normal Category Aeroplanes Certification,’’ without changes, are accepted as means of complying with the airworthiness requirements of amendment 23–64, 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. This document accepts only the revisions of standards referenced in ASTM Standard F3264–19, ‘‘Standard Specification for Normal Category Aeroplanes Certification.’’ 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 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. Amendment 23–64 established airworthiness requirements based on the level of safety of amendment 23–63 regulations, except for areas addressing loss of control and icing where the safety level was increased. Achieving this level of safety through compliance with amendment 23–64—for a given certification project—may require use of additional means of compliance beyond those accepted by this notice, depending on the details of the specific design. For example, applicants with novel designs, such as unmanned airplanes or vertical takeoff and landing airplanes that are outside the scope and applicability of these consensus standards must propose alternative means of compliance, applicable to their designs, to be accepted under § 23.2010. Further information on supplemental means of compliance is provided in a part 23 means of compliance summary table and in the Small Airplanes Issues List, which are available on the Small Airplanes—Regulations, Policies & Guidance website.5 Means of Compliance Accepted in this Policy: The following is a list of part 23, amendment 23–64, sections 59401 followed by their corresponding means of compliance accepted by this notice. However, for means of compliance identified in the following list, Aircraft Type Code compliance matrix tables, which define applicability of the individual requirements of given standards, are not accepted in any ASTM F44 standard. Due to errors identified in the Aircraft Type Code compliance matrix tables, applicability of individual requirements of standards must be established with the Small Airplane Standards Branch. 23.1457: ASTM F3264–19, section 9.12 23.1459: ASTM F3264–19, section 9.13 23.1529: ASTM F3264–19, section 10.6 Subpart B—Flight 23.2100: ASTM F3264–19, section 5.1 23.2105: ASTM F3264–19, section 5.2 23.2110: ASTM F3264–19, section 5.3 23.2115: ASTM F3264–19, section 5.4 23.2120: ASTM F3264–19, section 5.5 23.2125: ASTM F3264–19, section 5.6 23.2130: ASTM F3264–19, section 5.7 23.2135: ASTM F3264–19, section 5.8, combined with the changes in the following table: Replace: With: ASTM F3173/F3173M–18, Section 4.3.2.

The trimming controls shall not be adjusted during the maneuvers.’’ FAA Section 4.3.2.3 ‘‘With landing gear and flaps extended, power necessary to maintain level flight at 1.1 VS0, and the airplane as nearly as possible in trim, it shall be possible to maintain approximately level flight while retracting the flaps as rapidly as possible with simultaneous application of maximum continuous power. If the level acceleration will result in exceeding VFE of the initial flap configuration prior to the flaps reaching their selected setting, power may be reduced after achieving 1.3 VFE of the initial flap configuration. The maneuver continues until the flaps reach the selected setting and the airplane achieves VFE of the initial flap configuration. If gated flap positions are provided, the flap retraction may be demonstrated in stages with power and trim reset for level flight at 1.1 VS1, in the initial configuration for each stage: (1) From the fully extended position to the most extended gated position; (2) Between intermediate gated positions, if applicable; and (3) From the least extended gated position to the fully retracted position.’’ FAA Section 4.7 ‘‘It shall be possible, while in the landing configuration, to complete a landing without causing substantial damage or serious injury, and without exceeding the temporary one-hand control force limits specified in Table 1, appropriate for the type of control, following an approach to land under the following conditions;’’ FAA Section 5.3.1.3 ‘‘In a descent with idle power at a speed of 1.3 VS0 with landing gear extended and wing flaps in the landing position.’’ FAA Section 9.3.4 ‘‘If the procedure set forth in 9.3.3.2 is used to demonstrate compliance and marginal conditions existing during flight test with regard to reversal of primary longitudinal control force, flight tests shall be accomplished from the normal acceleration at which a marginal stick force per g condition is found to exist to the applicable limit specified in 9.3.2.1.’’ ASTM F3173/F3173M–18, Section 4.3.2.3.

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. ASTM reapproves a standard— denoted by the year of reapproval in parentheses (e.g., F2427–05a(2013))—to indicate 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., F3235–17e1)—to correct information that does not change the meaning or intent of a standard. Any means of compliance accepted by this notice that is based on a standard later reapproved or editorially changed is also considered accepted without the need for a NOA.

14 CFR Part 23

[Docket No. FAA-2020-0798; Notice No. 23-20-01-NOA]


Accepted Means of Compliance; Airworthiness Standards: Normal 
Category Airplanes

AGENCY: Federal Aviation Administration, DOT

ACTION: Notification of availability.

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

SUMMARY: This document announces the availability of means of 
compliance to the applicable airworthiness standards for normal 
category airplanes. The Administrator finds these means of compliance 
to be an acceptable means, but not the only means, of showing 
compliance to the applicable airworthiness standards for normal 
category airplanes and that they provide an appropriate level of 
safety.

DATES: Effective September 22, 2020.

FOR FURTHER INFORMATION CONTACT: Andy Supinie, Federal Aviation 
Administration, Policy and Innovation Division, Small Airplane 
Standards Branch, AIR-690, 901 Locust Street, Room 301, Kansas City, 
Missouri 64106; telephone (316) 946-4150; facsimile: (316) 946-4107;

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 lop 
consensus standards for use as a means of compliance in certificating 
small airplanes under Title 14, Code of Federal Regulations (14 CFR) 
part 23. In promulgating part 23, amendment 23-64 \3\ (81 FR 96572, 
December 30, 2016), the FAA explained that if it determined such 
consensus standards were acceptable means of compliance to part 23, it 
would publish a notice of availability of those consensus standards in 
the Federal Register.

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

    Pursuant to FAA Advisory Circular 23.2010-1,\4\ ``FAA Accepted 
Means of Compliance Process for 14 CFR part 23,'' section 3.1.1, this 
notice serves as a formal acceptance by the Administrator of means of 
compliance based on consensus standards developed by ASTM. The means of 
compliance accepted by this notice are one means, but not the only 
means of complying with part 23 regulatory requirements.
---------------------------------------------------------------------------

    \4\ See https://rgl.faa.gov/.

    The FAA reviewed 35 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 finds 
sections of ASTM Standard F3264-19, ``Standard Specification for Normal 
Category Aeroplanes Certification,'' without changes, are accepted as 
means of complying with the airworthiness requirements of amendment 23-
64, 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.
    This document accepts only the revisions of standards referenced in 
ASTM Standard F3264-19, ``Standard Specification for Normal Category 
Aeroplanes Certification.'' 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 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.
    Amendment 23-64 established airworthiness requirements based on the 
level of safety of amendment 23-63 regulations, except for areas 
addressing loss of control and icing where the safety level was 
increased. Achieving this level of safety through compliance with 
amendment 23-64--for a given certification project--may require use of 
additional means of compliance beyond those accepted by this notice, 
depending on the details of the specific design. For example, 
applicants with novel designs, such as unmanned airplanes or vertical 
takeoff and landing airplanes that are outside the scope and 
applicability of these consensus standards must propose alternative 
means of compliance, applicable to their designs, to be accepted under 
Sec.  23.2010.
    Further information on supplemental means of compliance is provided 
in a part 23 means of compliance summary table and in the Small 
Airplanes Issues List, which are available on the Small Airplanes--
Regulations, Policies & Guidance website.\5\

    Means of Compliance Accepted in this Policy: The following is a 
list of part 23, amendment 23-64, sections followed by their 
corresponding means of compliance accepted by this notice. However, for 
means of compliance identified in the following list, Aircraft Type 
Code compliance matrix tables, which define applicability of the 
individual requirements of given standards, are not accepted in any 
ASTM F44 standard. Due to errors identified in the Aircraft Type Code 
compliance matrix tables, applicability of individual requirements of 
standards must be established with the Small Airplane Standards Branch.

23.2620: ASTM F3264-19, sections 5.15 AND 10.5
    Editorial, reapproval, revision or withdrawal: The FAA expects a 
suitable consensus standard to be reviewed periodically. 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. ASTM 
reapproves a standard--denoted by the year of reapproval in parentheses 
(e.g., F2427-05a(2013))--to indicate 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)--to correct information that does 
not change the meaning or intent of a standard. Any means of compliance 
accepted by this notice that is based on a standard later reapproved or 
editorially changed is also considered accepted without the need for a 
NOA. 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 notice will not be automatically accepted 
and will require further FAA acceptance in order for the revisions to 
be an accepted means of compliance.
