SUPPLEMENTARY INFORMATION:
Comments Invited
The FAA invites you to send any written data, views, or arguments
about this final rule. Send your comments to an address listed under
ADDRESSES. Include ``Docket No. FAA-2022-1649; Project Identifier MCAI-
2022-01206-E'' at the beginning of your comments. The most helpful
comments reference a specific portion of the final rule, explain the
reason for any recommended change, and include supporting data. The FAA
will consider all comments received by the closing date and may amend
this final rule because of those comments.
Except for Confidential Business Information (CBI) as described in
the following paragraph, and other information as described in 14 CFR
11.35, the FAA will post all comments received, without change, to
<a href="http://regulations.gov">regulations.gov</a>, including any personal information you provide. The
agency will also post a report summarizing each substantive verbal
contact received about this final rule.
Confidential Business Information
CBI is commercial or financial information that is both customarily
and actually treated as private by its owner. Under the Freedom of
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public
disclosure. If your comments responsive to this AD contain commercial
or financial information that is customarily treated as private, that
you actually treat as private, and that is relevant or responsive to
this AD, it is important that you clearly designate the submitted
comments as CBI. Please mark each page of your submission containing
CBI as ``PROPIN.'' The FAA will treat such marked submissions as
confidential under the FOIA, and they will not be placed in the public
docket of this AD. Submissions containing CBI should be sent to Sungmo
Cho, Aviation Safety Engineer, ECO Branch, FAA, 1200 District Avenue,
Burlington, MA 01803. Any commentary that the FAA receives which is not
specifically designated as CBI will be placed in the public docket for
this rulemaking.
Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2022-0184, dated September 2, 2022
(EASA AD 2022-0184) (referred to after this as ``the MCAI''), to
correct an unsafe condition for all RRD TAY 620-15 and TAY 650-15 model
turbofan engines. The MCAI states that cracks on attachment bolts have
been reported which, if not detected and corrected, could result in
failure of HPT stage 1 and stage 2 rotor disks, high energy debris
release, damage to the airplane, and reduced control of the airplane.
The FAA is issuing this AD to address the unsafe condition on these
products.
You may examine the MCAI in the AD docket under Docket No. FAA-
2022-1649.
Related Service Information Under 1 CFR Part 51
The FAA reviewed EASA AD 2022-0184, dated September 2, 2022, which
specifies procedures for repetitive inspections of the HPT stage 2
intermediate air seal and attachment bolts and, depending on the
findings, replacement of all damaged parts.
This material is reasonably available because the interested
parties have access to it through their normal course of business or by
the means identified in ADDRESSES.
FAA's Determination
These products have been approved by the aviation authority of
another country, and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with the State of Design
Authority, it has notified the FAA of the unsafe condition referenced
in the MCAI described above. The FAA is issuing this AD after
determining that the unsafe condition described previously is likely to
exist or develop in other products of the same type design.
AD Requirements
This AD requires accomplishing the actions specified in EASA AD
2022-0184, described previously, except for any differences identified
as exceptions in the regulatory text of this AD and except as discussed
under ``Differences Between this AD and the MCAI.''
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has since
coordinated with other manufacturers and CAAs to use this process. As a
result, EASA AD 2022-0184 will be incorporated by reference in this
final rule. This AD, therefore, requires compliance with EASA AD 2022-
0184 in its entirety through that incorporation, except for any
differences identified as exceptions in the regulatory text of this AD.
Using common terms that are the same as the heading of a particular
section in the EASA AD does not mean that operators need comply only
with that section. For example, where the AD requirement refers to
``all required actions and compliance times,'' compliance with this AD
requirement is not limited to the section titled ``Required Action(s)
and Compliance Time(s)'' in EASA AD 2022-0184. Service information
required by the EASA AD for compliance will be available at
<a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2022-1649.
Differences Between This AD and the MCAI
Where EASA AD 2022-0184 requires replacement of all damaged parts,
this AD requires replacement of attachment bolts and the HPT stage 1
and stage 2 rotor disks.
Justification for Immediate Adoption and Determination of the Effective
Date
Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and
comment procedures for rules when the agency, for ``good cause,'' finds
that those procedures are ``impracticable, unnecessary, or contrary to
the public interest.'' Under this section, an agency, upon finding good
cause, may issue a final rule without providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.
There are currently no domestic operators of these products.
Accordingly, notice and opportunity for prior public comment are
unnecessary, pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the
foregoing reason, the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in less than 30 days
for the same reasons the FAA found good cause to forego notice and
comment.
Regulatory Flexibility Act
The requirements of the Regulatory Flexibility Act (RFA) do not
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt
a rule without prior notice and comment. Because the FAA has determined
that it has good cause to adopt this rule without notice and comment,
RFA analysis is not required.
[[Page 79800]]
Costs of Compliance
Currently, there are no U.S. registered airplanes with the affected
engines installed. If an affected engine is installed on an airplane,
or if an airplane with an affected engine is imported and placed on the
U.S. Register in the future, the FAA provides the following cost
estimates to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Repetitive inspection of the HPT 3 work-hours x $85 per $0 $255 $0
stage 2 intermediate air seal and hour = $255.
attachment bolts.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary
replacements that would be required based on the results of the
inspection.
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Replace attachment bolts and HPT stage 1 and 6 work-hours x $85 per hour = $280,189 $280,699
stage 2 rotor disks. $510.
----------------------------------------------------------------------------------------------------------------
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs
describes in more detail the scope of the Agency's authority.
The FAA is issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: General requirements.
Under that section, Congress charges the FAA with promoting safe flight
of civil aircraft in air commerce by prescribing regulations for
practices, methods, and procedures the Administrator finds necessary
for safety in air commerce. This regulation is within the scope of that
authority because it addresses an unsafe condition that is likely to
exist or develop on products identified in this rulemaking action.
Regulatory Findings
This AD will not have federalism implications under Executive Order
13132. This AD will not have a substantial direct effect on the States,
on the relationship between the national government and the States, or
on the distribution of power and responsibilities among the various
levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866, and
(2) Will not affect intrastate aviation in Alaska.
