ACTION: Issuance of accepted means of compliance. AGENCY: 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 sideby-side view, linking applicable regulations to the associated ASTM sections. SUMMARY: The FAA accepts the means of compliance effective March 11, 2022. FOR FURTHER INFORMATION CONTACT: Hieu Nguyen, Federal Aviation Administration, Policy and Innovation Division, Small Airplane Strategic Policy Section, AIR–615, 901 Locust Street, Room 301, Kansas City, Missouri 64106; telephone (316) 946–4123; facsimile: (316) 946–4107; email: hieu.nguyen@faa.gov. SUPPLEMENTARY INFORMATION: DATES: 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 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. 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. 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. 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. 13911 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 § 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.’’ 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.

ACTION: Final rule. AGENCY: The FAA is superseding Airworthiness Directive (AD) 2019–03– 01 and AD 2021–05–51 for certain Pratt & Whitney Division (PW) PW4074, PW4074D, PW4077, PW4077D, PW4084D, PW4090, and PW4090–3 model turbofan engines. AD 2019–03– 01 required performing initial and repetitive thermal acoustic image (TAI) inspections for cracks in certain 1ststage low-pressure compressor (LPC) blades and removal of those blades that fail inspection. AD 2021–05–51 required performing a one-time TAI inspection for cracks in certain 1st-stage LPC blades and removal of those blades that fail inspection. This AD was prompted by three in-flight failures of a 1st-stage LPC blade, with one failure resulting in an engine fire during flight, and subsequent manufacturer publication of service information specifying improved inspections for three critical locations on the 1st-stage LPC blade. This AD requires initial and repetitive ultrasonic (UT) inspections and TAI inspections for cracks in certain 1st-stage LPC blades and removal of those blades that fail inspection. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective April 15, 2022. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of April 15, 2022.

AD 2019–03–01 and AD 2021–05–51 applied to certain PW PW4074, PW4074D, PW4077, PW4077D, PW4084D, PW4090, and PW4090–3 model turbofan engines. The NPRM published in the Federal Register on December 28, 2021 (86 FR 73699). The NPRM was prompted by the manufacturer developing an improved UT inspection for the three critical locations on the 1st-stage LPC blade, two at the mid span region of the blade and one at the flow path region of the blade, following three in-flight failures of a 1st-stage LPC blade, with one failure resulting in an engine fire during flight. The manufacturer published Pratt & Whitney Alert Service Bulletin (ASB) PW4G–112–A72–361, dated October 15, 2021, which provides instructions for performing both the improved UT inspection and the TAI inspection. The manufacturer also determined that it was necessary to adjust the initial TAI inspection threshold and lower the Frm 00023 Fmt 4700 Sfmt 4700 repetitive TAI inspection interval on the 1st-stage LPC blades to address the unsafe condition. In the NPRM, the FAA proposed to require initial and repetitive UT inspections and TAI inspections for cracks in certain 1ststage LPC blades and removal of those blades that fail inspection. Discussion of Final Airworthiness Directive Comments Background PO 00000 13923 The FAA received comments from five commenters. The commenters were Air Line Pilots Association, International (ALPA), All Nippon Airways (ANA), The Boeing Company (Boeing), Japan Airlines (JAL), and United Airlines (UAL). The following presents the comments received on the NPRM and the FAA’s response to each comment. Request To Revise Note and Add Additional Note in Required Actions UAL requested that the FAA revise Note 2 to paragraph (g)(1)(ii) of the NPRM [Note 1 to paragraph (g)(1)(ii) of this AD] to ‘‘The FAA-approved TAI inspection method and the vendors that can perform the FAA-approved TAI inspection are specified in the Accomplishment Instructions section and Vendor Services section of PW4G– 112–A72–361, respectively.’’ UAL also requested that the FAA add the same note to paragraph (g)(2)(iii) of this AD. The FAA agrees and revised Note 1 to paragraph (g)(1)(ii) of this AD and added Note 2 to paragraph (g)(2)(iii) to this AD, as requested by UAL. Request To Change the Initial Compliance Time to Before Revenue Flight ANA requested that the FAA change the Required Actions, paragraph (g)(1) Initial 1st-stage LPC Blade Inspections, from ‘‘before further flight after the effective of this AD’’ to ‘‘before the next revenue flight’’ to clarify the ferry flight requirement. Similarly, JAL requested the FAA change the Required Actions, paragraph (g)(1) Initial 1st-stage LPC Blade Inspections, from ‘‘before further flight after the effective of this AD’’ to ‘‘before the next revenue flight’’ or ‘‘before further flight except the ferry flight without passenger and cargos.’’ The FAA disagrees with changing the initial compliance in paragraph (g) of this AD as requested by ANA and JAL. The FAA has determined it is necessary to require certain actions prior to any flight, except as permitted in paragraph (i), Special Flight Permit, of this AD. E:\FR\FM\11MRR1.SGM 11MRR1

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/.

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.
