14 CFR Part 23

[Notice No. 23-18-01-NOA]

Accepted Means of Compliance; Airworthiness Standards: Normal 
Category Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notification of availability; request for comments.

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

SUMMARY: This document announces the availability of 63 Means of 
Compliance (MOC) based on 30 published ASTM International (ASTM) 
consensus standards developed by ASTM Committee F44 on General Aviation 
Aircraft. A total of 46 of these accepted MOCs consist of ASTM 
consensus standards as published, with the remaining 17 MOCs comprised 
of a combination of ASTM standards and FAA changes. The Administrator 
finds these MOCs to be an acceptable means, but not the only means, of 
showing compliance to the applicable regulations in part 23, amendment 
23-64, for normal category airplanes. The Administrator further finds 
that these accepted means of complying with part 23, amendment 23-64, 
provide at least the same level of safety as the corresponding 
requirements in part 23, amendment 23-63.

DATES: Comments must be received on or before July 10, 2018.

ADDRESSES: Mail comments to: Federal Aviation Administration, Policy 
and Innovation Division, Small Airplane Standards Branch, AIR-690, 
Attention: Steve Thompson, 901 Locust Street, Room 301, Kansas City, 
Missouri 64106. Comments may also be emailed to: 
[email protected]. Specify the MOC, and if applicable, the 
standard being addressed by designation and title. Mark all comments: 
Part 23 MOC Comments.

Administration, Policy and Innovation Division, Small Airplane 
Standards Branch, AIR-690, 901 Locust Street, Room 301, Kansas City,

SUPPLEMENTARY INFORMATION: 

Comments Invited

    Interested persons are invited to submit written comments, data, or 
views. Communications should identify the MOC and consensus standard 
number, where applicable, and be submitted to the address previously 
specified in the ADDRESSES section of this NOA. The most helpful 
comments reference a specific portion of the accepted MOC(s) or 
standard(s), explain the reason for any recommended change, and include 
supporting data. The FAA may forward communications regarding the 
consensus standards to ASTM Committee F44 for consideration. The MOC or 
standard may be revised based on received comments. The FAA will 
consider all comments received during the recurring review of the MOC 
and consensus standard and will participate in the consensus standard 
revision process.

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 through 
ASTM to develop consensus standards for use as a MOC in certificating 
small airplanes under part 23. In promulgating part 23, amendment 23-
64, the FAA explained that if it determined such consensus standards 
were acceptable MOC 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, section 3.1.1, this 
document serves as a formal acceptance by the Administrator, of MOCs 
based on consensus standards developed by ASTM. The MOCs accepted by 
this document are one means, but not the only means of complying with 
part 23 regulatory requirements.
    The FAA has reviewed the consensus standards referenced in this NOA 
as the basis for MOCs to the regulatory requirements of part 23, 
amendment 23-64. In some cases, the Administrator finds sections of 
ASTM Standard F3264-17, ``Standard Specification for Normal Category 
Aeroplanes Certification,'' without changes, are accepted as means of 
complying with the airworthiness requirements of part 23, without 
degrading safety, and within the scope and applicability of the 
consensus standards. In other cases, the MOCs, while based on ASTM 
consensus standards, include additional FAA provisions necessary to 
comply with the airworthiness requirements of part 23, amendment 23-64.
    Part 23, amendment 23-64, established airworthiness requirements 
based on the level of safety of

[[Page 21851]]

amendment 23-63 regulations, except for areas addressing loss of 
control and icing where the safety level was increased.\3\ Achieving 
this level of safety through compliance with amendment 23-64--for a 
given certification project--may require use of additional MOCs beyond 
those accepted by this document, depending on the details of the 
specific design. For example, an applicant's design may include 
features that are customary, but not addressed in the MOCs accepted by 
this document. Designs may also include features that are innovative 
and not type certificated previously. In either case, a supplemental 
MOC beyond those accepted in this document would be required. For 
example, the MOCs accepted by this document do not contain provisions 
addressing powered-trim system runaways. Therefore, in order to 
maintain the level of safety of amendment 23-63 regulations, applicants 
proposing use of these MOCs for an airplane with a powered-trim system 
would need to supplement the accepted MOC(s) with additional means for 
Sec.  23.2300 to demonstrate safe controllability after a probable trim 
system runaway. To do this, applicants could use the provisions of 
Sec.  23.677(d), amendment 23-49, or other MOC(s) accepted under Sec.  
23.2010. Further information on supplemental MOCs 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.\4\

23.2620: ASTM F3264-17, 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 (F3235-17 [egr]\1\)--to correct 
information that does not change the meaning or intent of a standard. 
Any MOC accepted by this document 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 MOC accepted by this document will not be automatically 
accepted and will require further FAA acceptance in order for the 
revisions to be an accepted MOC.
