SUPPLEMENTARY INFORMATION:
Discussion
On March 21, 2020, the FAA issued
Emergency AD 2020–07–51, which
requires removal from service of
affected HPT 1st-stage disks installed on
IAE V2522–A5, V2524–A5, V2525–D5,
V2527–A5, V2527E–A5, V2527M–A5,
V2528–D5, V2530–A5, and V2533–A5
model turbofan engines. This emergency
AD was sent previously to all known
U.S. owners and operators of these
engines. This action was prompted by
investigative findings from an event that
occurred on March 18, 2020, in which
an Airbus Model A321–231 airplane,
powered by IAE V2533–A5 model
turbofan engines, experienced an
uncontained HPT 1st-stage disk failure
that resulted in an aborted takeoff. This
condition, if not addressed, could result
in uncontained HPT failure, release of
high-energy debris, damage to the
engine, damage to the airplane, and loss
of the airplane.
FAA’s Determination
The FAA is issuing this AD because
the Agency evaluated all the relevant
information and determined the unsafe
condition described previously is likely
to exist or develop in other products of
the same type design.
AD Requirements
This AD requires removal from
service of affected HPT 1st-stage disks
installed on IAE V2522–A5, V2524–A5,
V2525–D5, V2527–A5, V2527E–A5,
V2527M–A5, V2528–D5, V2530–A5,
and V2533–A5 model turbofan engines.
Interim Action
The FAA considers this AD interim
action. The root cause of this event is
still under investigation.
FAA’s Justification and Determination
of the Effective Date
Section 553(b)(3)(B) of the
Administrative Procedure Act (APA) (5
E:\FR\FM\13APR1.SGM
13APR1
Federal Register / Vol. 85, No. 71 / Monday, April 13, 2020 / Rules and Regulations
U.S.C.) 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
seeking comment prior to the
rulemaking. Similarly, Section 553(d) of
the APA authorizes agencies to make
rules effective in less than 30 days,
upon a finding of good cause.
An unsafe condition exists that
required the immediate adoption of
Emergency AD 2020–07–51, issued on
March 21, 2020, to all known U.S.
owners and operators of these engines.
The FAA has found that the risk to the
flying public justifies forgoing notice
and comment prior to adoption of this
rule. On March 18, 2020, an Airbus
Model A321–231 airplane, powered by
IAE V2533–A5 model turbofan engines,
experienced an uncontained HPT 1ststage disk failure that resulted in an
aborted takeoff. The uncontained failure
of the HPT 1st-stage disk resulted in
high-energy debris penetrating the
engine cowling. This unsafe condition,
caused by an uncontained HPT 1st-stage
disk failure, may result in loss of the
airplane.
The FAA considers removal of the
affected HPT 1st-stage disks to be an
urgent safety issue. Removal of the
affected HPT 1st-stage disks must be
accomplished within 5 cycles after the
effective date of this AD. These
conditions still exist and the AD is
hereby published in the Federal
Register as an amendment to section
39.13 of the Federal Aviation
Regulations (14 CFR 39.13) to make it
effective to all persons. Accordingly,
notice and opportunity for prior public
comment are impracticable and contrary
to public interest pursuant to 5 U.S.C.
553(b)(3)(B). In addition, for the reasons
stated above, 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.
Comments Invited
This AD is a final rule that involves
requirements affecting flight safety and
was not preceded by notice and an
opportunity for public comment.
However, the FAA invites you to send
any written data, views, or arguments
about this final rule. Send your
comments to an address listed under the
ADDRESSES section. Include the docket
number FAA–2020–0314 and Product
Identifier AD–2020–00369–E at the
beginning of your comments. The FAA
specifically invite comments on the
overall regulatory, economic,
environmental, and energy aspects of
this final rule. 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 https://
www.regulations.gov, including any
personal information you provide. The
FAA will also post a report
summarizing each substantive verbal
contact received about this AD.
Confidential Business Information
Confidential Business Information
(CBI) is commercial or financial
20403
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 Nicholas J. Paine,
Aerospace 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.
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 FAA
has determined that it has good cause to
adopt this rule without notice and
comment, RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD
affects 2 engines installed on airplanes
of U.S. registry.
The FAA estimates the following
costs to comply with this AD:

SUPPLEMENTARY INFORMATION:
Discussion
On March 21, 2020, the FAA issued Emergency AD 2020-07-51, which
requires removal from service of affected HPT 1st-stage disks installed
on IAE V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5,
V2528-D5, V2530-A5, and V2533-A5 model turbofan engines. This emergency
AD was sent previously to all known U.S. owners and operators of these
engines. This action was prompted by investigative findings from an
event that occurred on March 18, 2020, in which an Airbus Model A321-
231 airplane, powered by IAE V2533-A5 model turbofan engines,
experienced an uncontained HPT 1st-stage disk failure that resulted in
an aborted takeoff. This condition, if not addressed, could result in
uncontained HPT failure, release of high-energy debris, damage to the
engine, damage to the airplane, and loss of the airplane.
FAA's Determination
The FAA is issuing this AD because the Agency evaluated all the
relevant information and determined the unsafe condition described
previously is likely to exist or develop in other products of the same
type design.
AD Requirements
This AD requires removal from service of affected HPT 1st-stage
disks installed on IAE V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-
A5, V2527M-A5, V2528-D5, V2530-A5, and V2533-A5 model turbofan engines.
Interim Action
The FAA considers this AD interim action. The root cause of this
event is still under investigation.
FAA's Justification and Determination of the Effective Date
Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5
[[Page 20403]]
U.S.C.) 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 seeking comment prior to the
rulemaking. Similarly, Section 553(d) of the APA authorizes agencies to
make rules effective in less than 30 days, upon a finding of good
cause.
An unsafe condition exists that required the immediate adoption of
Emergency AD 2020-07-51, issued on March 21, 2020, to all known U.S.
owners and operators of these engines. The FAA has found that the risk
to the flying public justifies forgoing notice and comment prior to
adoption of this rule. On March 18, 2020, an Airbus Model A321-231
airplane, powered by IAE V2533-A5 model turbofan engines, experienced
an uncontained HPT 1st-stage disk failure that resulted in an aborted
takeoff. The uncontained failure of the HPT 1st-stage disk resulted in
high-energy debris penetrating the engine cowling. This unsafe
condition, caused by an uncontained HPT 1st-stage disk failure, may
result in loss of the airplane.
The FAA considers removal of the affected HPT 1st-stage disks to be
an urgent safety issue. Removal of the affected HPT 1st-stage disks
must be accomplished within 5 cycles after the effective date of this
AD. These conditions still exist and the AD is hereby published in the
Federal Register as an amendment to section 39.13 of the Federal
Aviation Regulations (14 CFR 39.13) to make it effective to all
persons. Accordingly, notice and opportunity for prior public comment
are impracticable and contrary to public interest pursuant to 5 U.S.C.
553(b)(3)(B). In addition, for the reasons stated above, 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.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment. However, the FAA invites you to send any written data, views,
or arguments about this final rule. Send your comments to an address
listed under the ADDRESSES section. Include the docket number FAA-2020-
0314 and Product Identifier AD-2020-00369-E at the beginning of your
comments. The FAA specifically invite comments on the overall
regulatory, economic, environmental, and energy aspects of this final
rule. 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
https://www.regulations.gov, including any personal information you
provide. The FAA will also post a report summarizing each substantive
verbal contact received about this AD.
Confidential Business Information
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 Nicholas J. Paine, Aerospace 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.
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 FAA has determined
that it has good cause to adopt this rule without notice and comment,
RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 2 engines installed on
airplanes of U.S. registry.
The FAA estimates the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor Cost Parts Cost product operators
----------------------------------------------------------------------------------------------------------------
Remove 1st-stage HPT disk............. 226 work-hours x $85 per $335,690 $354,900 $709,800
hour = $19,210.
----------------------------------------------------------------------------------------------------------------
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.

(e) Unsafe Condition
This AD was prompted by investigative findings from an event
involving an uncontained failure of a HPT 1st-stage disk that
resulted in high-energy debris penetrating the engine cowling. The
FAA is issuing this AD to prevent failure of the HPT. The unsafe
condition, if not addressed, could result in uncontained HPT
failure, release of high-energy debris, damage to the engine, damage
to the airplane, and loss of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Required Actions
(1) For affected IAE model turbofan engines with an engine
serial number and HPT 1st-stage disk serial number listed in Table 1
to paragraph (g)(1) of this AD, within 5 flight cycles after the
effective date of this AD, remove the HPT 1st-stage disk from
service.
