Airworthiness Directives; International Aero Engines, LLC Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comment; correction.
-----------------------------------------------------------------------
SUMMARY: The FAA is correcting an airworthiness directive (AD) that was
published in the Federal Register. That AD applies to certain
International Aero Engines, LLC (IAE LLC) Model PW1124G1-JM, PW1127G-
JM, PW1127GA-JM, PW1129G-JM, PW1130G-JM, PW1133G-JM, and PW1133GA-JM

date of AD 2023-20-11 remains November 1, 2023.

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-2023-1996 and Project Identifier
AD-2022-01361-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
regulations.gov, 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 Mark
Taylor, Aviation Safety Engineer, FAA, 2200 South 216th Street, Des
Moines, WA 98198. Any commentary that the FAA receives which is not
specifically designated as CBI will be placed in the public docket for
this rulemaking.
Background
AD 2023-20-11, Amendment 39-22570 (88 FR 71466, October 17, 2023),
requires replacement of the high-pressure compressor (HPC) rear hub
with a part eligible for installation for certain IAE LLC Model
PW1124G1-JM, PW1127G-JM, PW1127GA-JM, PW1129G-JM, PW1130G-JM, PW1133G-
JM, and PW1133GA-JM engines.
Need for Correction
As published, paragraph (c) in the regulatory text of AD 2023-20-11
is incorrect. Paragraph (c) of AD 2023-20-11 refers to part number
``30G4008.'' The correct reference is part number ``30G4008 or
30G8208.''
Related Service Information Under 1 CFR Part 51
The FAA reviewed Pratt & Whitney Service Bulletin PW1000G-C-72-00-
0209-00A-930A-D, Issue No: 002, dated June 20, 2023, which provides the
list of affected serial numbers for the HPC rear hub.
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.
Correction of Publication
This document corrects an error and correctly adds the AD as an
amendment to 14 CFR 39.13. Although no other part of the preamble or
regulatory information has been corrected, the FAA is publishing the
entire rule in the Federal Register.
The effective date of this AD remains November 1, 2023.
[[Page 74025]]
Since this action only corrects the mention of an affected part
number, it has no adverse economic impact and imposes no additional
burden on any person. Therefore, the FAA has determined that notice and
public comment procedures are unnecessary.
List of Subjects in 14 CFR Part 39

reference, Safety.
Adoption of the Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the FAA amends part 39 of the Federal Aviation
Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Corrected]
0
2. The FAA amends Sec. 39.13 by adding the following airworthiness
directive:
2023-20-11 International Aero Engines, LLC: Amendment 39-22570;
Docket No. FAA-2023-1996; Project Identifier AD-2022-01361-E.
(a) Effective Date
This airworthiness directive (AD) is effective November 1, 2023.
(b) Affected ADs
None.
(c) Applicability
This AD applies to International Aero Engines, LLC Model
PW1124G1-JM, PW1127G-JM, PW1127GA-JM, PW1129G-JM, PW1130G-JM,
PW1133G-JM, and PW1133GA-JM engines with an installed high-pressure
compressor (HPC) rear hub, part number 30G4008 or 30G8208, with a
serial number (S/N) listed in Table 2 or Table 3 of Pratt & Whitney
Service Bulletin PW1000G-C-72-00-0209-00A-930A-D, Issue No: 002,
dated June 20, 2023 (PW1000G-C-72-00-0209-00A-930A-D, Issue No:
002).
(d) Subject
Joint Aircraft System Component (JASC) Code 7230, Turbine Engine
Compressor Section.
(e) Unsafe Condition
This AD was prompted by a manufacturer investigation which
revealed that Maintenance, Repair, and Overhaul shops were
misinterpreting accepted knife edge coating wear limits. The FAA is
issuing this AD to prevent heat-induced cracking at the forward and
aft knife edge seals and uncontained separation of the HPC rear hub.
The unsafe condition, if not addressed, could result in uncontained
debris release, damage to the engine, damage to the airplane, in-
flight shutdown, and loss of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Required Actions
At the next engine shop visit after the effective date of this
AD, replace the HPC rear hub with a part eligible for installation.
(h) Definitions
(1) For the purpose of this AD, a ``part eligible for
installation'' is:
(i) Any HPC rear hub with an S/N that does not appear in Table 2
or Table 3 of PW1000G-C-72-00-0209-00A-930A-D, Issue No: 002; or
(ii) Any HPC rear hub that has been serviced in accordance with
Pratt & Whitney Service Bulletin PW1000G-C-72-00-0209-00A-930A-D
(any revision).
(2) For the purpose of this AD, an ``engine shop visit'' is the
induction of an engine into the shop for maintenance involving the
separation of major mating engine flange H. The separation of engine
flanges solely for the purpose of transportation without subsequent
engine maintenance does not constitute an engine shop visit.
(i) Credit for Previous Actions
You may take credit for the actions required by paragraph (g) of
this AD if you performed those actions before the effective date of
this AD using Pratt & Whitney Service Bulletin PW1000G-C-72-00-0209-
00A-930A-D, Issue No: 001, dated September 13, 2022.
(j) Alternative Methods of Compliance (AMOCs)
(1) The Manager, AIR-520 Continued Operational Safety Branch,
FAA, has the authority to approve AMOCs for this AD, if requested
using the procedures found in 14 CFR 39.19. In accordance with 14
CFR 39.19, send your request to your principal inspector or local
Flight Standards District Office, as appropriate. If sending
information directly to the manager of the AIR-520 Continued
Operational Safety Branch, send it to the attention of the person
identified in paragraph (k) of this AD and email to: [email protected].
(2) Before using any approved AMOC, notify your appropriate
principal inspector, or lacking a principal inspector, the manager
of the local flight standards district office/certificate holding
district office.
