Background
On March 18, 2020, an Airbus Model A321-231 airplane, powered by
International Aero Engines AG (IAE AG) Model V2533-A5 engines,
experienced an uncontained HPT 1st-stage disk failure that resulted in
high-energy debris penetrating the engine cowling. Based on a
preliminary analysis of this event, on March 21, 2020, the FAA issued
Emergency AD 2020-07-51 (followed by publication in the Federal
Register on April 13, 2020, as a final
[[Page 57000]]
rule, request for comments (85 FR 20402)), which requires the removal
from service of certain HPT 1st-stage disks installed on IAE AG Model
V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5,
V2530-A5, and V2533-A5 engines. A manufacturer investigation found that
the failure of the HPT 1st-stage disk was a result of a material
anomaly attributed to deficiencies in the manufacturing process.
Based on the analysis performed since that March 2020 event, the
manufacturer, PW, identified a different population of HPT 1st-stage
disks and HPT 2nd-stage disks that are subject to the same unsafe
condition identified in AD 2020-07-51. In response, the FAA issued AD
2021-19-10, Amendment 39-21728 (86 FR 50610, September 10, 2021) (AD
2021-19-10), which requires the removal from service of certain HPT
1st-stage disks and HPT 2nd-stage disks installed on IAE LLC Model
PW1122G-JM, PW1124G1-JM, PW1124G-JM, PW1127G1-JM, PW1127GA-JM, PW1127G-
JM, PW1129G-JM, PW1130G-JM, PW1133GA-JM, and PW1133G-JM engines.
Since the FAA issued AD 2021-19-10, PW identified another
subpopulation of HPT 1st-stage disks and HPT 2nd-stage disks that,
because of their susceptibility to the same material anomaly, require
inspection and possible removal from service. In response, the FAA
issued AD 2022-19-15, Amendment 39-22184 (87 FR 59660, October 3, 2022;
corrected 87 FR 64156, October 24, 2022) (AD 2022-19-15), which
requires performing a USI of the HPT 1st-stage disk and HPT 2nd-stage
disk and, depending on the results of the inspections, replacement of
the HPT 1st-stage disk or HPT 2nd-stage disk installed on IAE LLC Model
PW1122G-JM, PW1124G1-JM, PW1124G-JM, PW1127G1-JM, PW1127GA-JM, PW1127G-
JM, PW1129G-JM, PW1130G-JM, PW1133GA-JM, and PW1133G-JM engines.
Since the FAA issued AD 2022-19-15, on December 24, 2022 an Airbus
Model A320neo airplane powered by IAE LLC Model PW1127GA-JM engines,
experienced an HPC IBR-7 failure that resulted in engine shutdown and
aborted take-off. Following this event, the manufacturer conducted a
records review of production and field-returned parts, and re-evaluated
their engineering analysis methodology. The new analysis identified HPT
1st-stage hubs and HPT 2nd-stage hubs that are susceptible to failure
much earlier than previously determined. On August 4, 2023, PW issued
service information to instructing operators to conduct a USI to detect
cracks and prevent premature failure. The new service information
necessitates action much earlier than the timing mandated in AD 2022-
19-15. The manufacturer's updated analysis also identified PW1400G
series engines that contain HPT 1st-stage hubs and HPT 2nd-stage hubs
that are also subject to this vulnerability and therefore need
immediate inspection. This condition, if not addressed, could result in
uncontained disk failure, release of high-energy debris, damage to the
engine, damage to the airplane, and loss of the airplane. The FAA is
issuing this AD to address the unsafe condition on these products.
FAA's Determination
The FAA is issuing this AD because the agency has determined the
unsafe condition described previously is likely to exist or develop in
other products of the same type design.
Related Service Information Under 1 CFR Part 51
The FAA reviewed PW Special Instruction No. 149F-23, dated August
4, 2023. This service information provides the list of affected HPT
1st-stage hubs and HPT 2nd-stage hubs, identified by part number and
serial number, installed on certain IAE LLC engines.
Pratt & Whitney Service Bulletin PW1000G-C-72-00-0188-00A-930A-D,
Issue No: 002, dated July 8, 2022, was previously approved for
incorporation by reference on November 7, 2022 (87 FR 59660, October 3,
2022; corrected 87 FR 64156, October 24, 2022).
This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in ADDRESSES.
AD Requirements
This AD requires performing a USI of the HPT 1st-stage hub and HPT
2nd-stage hub and, depending on the results of the inspections,
replacement of the HPT 1st-stage hub or HPT 2nd-stage hub.
Differences Between the AD and the Service Information
PW Service Bulletin PW1000G-C-72-00-0188-00A-930A-D, Issue No: 002,
dated July 8, 2022, includes only PW1100G-JM series engines in its
applicability. This AD applies to both PW1100G-JM series engines and
PW1400G-JM series engines.
Interim Action
The FAA considers this AD to be an interim action. This unsafe
condition is still under investigation by the manufacturer and,
depending on the results of that investigation, the FAA may consider
further rulemaking action.
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.
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies forgoing notice and comment prior to adoption of this rule.
The presence of material anomalies in the HPT 1st-stage hubs and HPT
2nd-stage hubs discovered after the December 24, 2022 engine shutdown
and aborted take-off could lead to premature fracture and uncontained
failure, which indicates an immediate safety of flight problem. The
manufacturer also recently conducted a records review of production and
field-returned parts, and re-evaluated their engineering analysis
methodology and identified HPT 1st-stage hubs and HPT 2nd-stage hubs
that require USI much earlier than previously required. The
manufacturer issued service information on August 4, 2023 instructing
operators to remove these engines from service by September 15, 2023
due to the urgency of the safety of flight issue. The longer these
parts remain in service, without the inspections required by this AD,
the higher the probability of failure. Therefore, the compliance time
for these required inspections is shorter than the time necessary for
the public to comment and for publication of the final rule.
Accordingly, notice and opportunity for prior public comment are
impracticable and contrary to the public interest pursuant to 5 U.S.C.
553(b)(3)(B).
In addition, the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in
[[Page 57001]]
less than 30 days, for the same reasons the FAA found good cause to
forgo 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 FAA has determined
that it has good cause to adopt this rule without prior notice and
comment, RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 20 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
----------------------------------------------------------------------------------------------------------------
USI the HPT 1st-stage hub............. 100 work-hours x $85 per $0 $8,500 $170,000
hour = $8,500.
USI the HPT 2nd-stage hub............. 100 work-hours x $85 per 0 8,500 170,000
hour = $8,500.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary
replacement that would be required based on the results of the
inspection. The agency has no way of determining the number of aircraft
that might need this replacement:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Replace HPT 1st-stage hub or HPT 2nd-stage hub 1 work-hours x $85 per hour = $171,000 $171,085
$85.
----------------------------------------------------------------------------------------------------------------
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.
