AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: The FAA is correcting an airworthiness directive (AD) that 
published in the Federal Register. That AD applies to certain 
International Aero Engines, LLC (IAE LLC) PW1122G-JM, PW1124G1-JM, 
PW1124G-JM, PW1127G1-JM, PW1127GA-JM, PW1127G-JM, PW1129G-JM, PW1130G-
JM, PW1133GA-JM, and PW1133G-JM model turbofan engines. The table 
numbers of the service information referenced in paragraphs (g)(2) and 
(3) are incorrect. This document corrects those errors. In all other 
respects, the original document remains the same.

DATES: This correction is effective November 7, 2022. The effective 
date of AD 2022-19-15 remains November 7, 2022.

SUPPLEMENTARY INFORMATION: AD 2022-19-15, Amendment 39-22184 (AD 2022-
19-15), requires performing an ultrasonic inspection (USI) of the high-
pressure turbine (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 for certain IAE LLC PW1122G-JM, 
PW1124G1-JM, PW1124G JM, PW1127G1-JM, PW1127GA-JM, PW1127G-JM, PW1129G-
JM, PW1130G-JM, PW1133GA-JM, and PW1133G-JM model turbofan engines.

Need for the Correction

    As published, the table numbers of the service information 
referenced in Required Actions, paragraphs (g)(2) and (3) of AD 2022-
19-15, are incorrect. The table numbers are incorrectly referenced in 
paragraphs (g)(2) and (3) as ``Table 2.'' and ``Table 3.,'' of Pratt & 
Whitney Service Bulletin (SB) PW1000G-C-72-00-0188-00A-930A-D, Issue 
No: 002, dated July 8, 2022. The correct table number for paragraph 
(g)(2) is ``Table 3.'' and for paragraph (g)(3) is ``Table 4.,'' of PW 
SB PW1000G-C-72-00-0188-00A-930A-D.
    No other part of the preamble or regulatory information has been 
changed; for convenience, the entire rule is being republished.
    The effective date of this AD remains November 7, 2022.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Pratt & Whitney SB PW1000G-C-72-00-0188-00A-930A-
D, Issue No: 002, dated July 8, 2022. This service information 
specifies procedures for performing a USI of the HPT 1st-stage disk and 
the HPT 2nd-stage disk, identified by part number and serial number, 
installed on IAE LLC PW1124G1-JM, PW1127G-JM, PW1127GA-JM, PW1129G-JM, 
PW1130G-JM, PW1133G-JM, and PW1133GA-JM model turbofan engines. 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.

Adoption of the Amendment

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration amends part 39 of 
the Federal Aviation Regulations (14 CFR part 39) by correcting 87 FR 
59660 (October 3, 2022) beginning at page 59663, column 3 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 corrects Sec.  39.13 by correcting the following 
airworthiness directive to read:

2022-19-15 International Aero Engines, LLC: Amendment 39-22184; 
Docket No. FAA-2022-0292; Project Identifier AD-2021-01297-E.

(a) Effective Date

    This airworthiness directive (AD) is effective November 7, 2022.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to International Aero Engines, LLC PW1122G-JM, 
PW1124G1-JM, PW1124G-JM, PW1127G1-JM, PW1127GA-JM, PW1127G-JM, 
PW1129G-JM, PW1130G-JM, PW1133GA-JM, and PW1133G-JM model turbofan 
engines with an installed:
    (1) High-pressure turbine (HPT) 1st-stage disk, part numbers (P/
Ns) 30G4201, 30G6201, or 30G7301; and
    (2) HPT 2nd-stage disk, P/Ns 30G3902, 30G5502, or 30G6602.

[[Page 64157]]

(d) Subject

    Joint Aircraft System Component (JASC) Code 7250, Turbine 
Section.

(e) Unsafe Condition

    This AD was prompted by an analysis of an event involving an 
International Aero Engines AG V2533-A5 model turbofan engine, which 
experienced an uncontained failure of an 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 1st-stage disk 
and HPT 2nd-stage disk. The unsafe condition, if not addressed, 
could result in uncontained HPT disk 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 engines that have not incorporated Pratt & 
Whitney (PW) Service Bulletin (SB) PW1000G-C-72-00-0112-00A-930A-D, 
at the next engine shop visit after the effective date of this AD, 
perform the following:
    (i) Ultrasonic inspection (USI) of the HPT 1st-stage disk using 
the Accomplishment Instructions, paragraph 9.A. or B., as 
applicable, of PW SB PW1000G-C-72-00-0188-00A-930A-D, Issue No: 002, 
dated July 8, 2022 (PW SB PW1000G-C-72-00-0188-00A-930A-D); and
    (ii) USI of the HPT 2nd-stage disk using the Accomplishment

serial number (S/N) identified in the Accomplishment Instructions, 
Table 3., of PW SB PW1000G-C-72-00-0188-00A-930A-D, at the next 
engine shop visit after the effective date of this AD, perform a USI 
of the HPT 1st-stage disk using the Accomplishment Instructions, 
paragraph 9.A. or B., as applicable, of PW SB PW1000G-C-72-00-0188-

an S/N identified in the Accomplishment Instructions, Table 4., of 
PW SB PW1000G-C-72-00-0188-00A-930A-D, at the next engine shop visit 
after the effective date of this AD, perform a USI of the HPT 2nd-

    (4) Based on the results of the USIs required by paragraphs 
(g)(1) through (3) of this AD, if any HPT 1st-stage disk or HPT 2nd-
stage disk does not pass the USI, as specified in the Accomplishment 
Instructions, paragraphs 9.A. through D., of PW SB PW1000G-C-72-00-
0188-00A-930A-D, as applicable, before further flight, remove the 
HPT 1st-stage disk or HPT 2nd-stage disk from service and replace 
with a part eligible for installation.
    (5) For affected engines that have incorporated PW SB PW1000G-C-
72-00-0112-00A-930A-D and do not require an inspection per paragraph 
(g)(2) or (3) of this AD, no further action is required.

(h) Definitions

    (1) For the purpose of this AD, a ``part eligible for 
installation'' is:
    (i) Any HPT 1st-stage disk that has passed the USI required by 
paragraphs (g)(1)(i) or (g)(2) of this AD.
    (ii) Any HPT 2nd-stage disk that has passed the USI required by 
paragraphs (g)(1)(ii) or (g)(3) of this AD.
    (iii) Any HPT 1st-stage disk that has incorporated PW SB 
PW1000G-C-72-00-0112-00A-930A-D and does not require an inspection 
per paragraph (g)(2) of this AD.
    (iv) Any HPT 2nd-stage disk that has incorporated PW SB PW1000G-
C-72-00-0112-00A-930A-D and does not require an inspection per 
paragraph (g)(3) of this AD.
    (v) Any HPT 1st-stage disk or HPT 2nd-stage disk with a 
certificate of conformance that shows ``PW1000G-C-72-00-0188-00A-
930A-D,'' ``1 CODE 45S,'' or identified by part marking ``21CC332'' 
or ``SB 72-0188.''
    (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 the ``M'' flange. Separation of the ``M'' flange 
solely for the purposes of transportation without subsequent engine 
maintenance does not constitute an engine shop visit.

(i) Credit for Previous Actions

    You may take credit for the USIs required by paragraphs (g)(1) 
through (3) of this AD if you performed the USIs before the 
effective date of this AD using PW SB PW1000G-C-72-00-0188-00A-930A-
D, Issue No: 001, dated September 13, 2021.

(j) Installation Prohibition

    After the effective date of this AD, do not install onto any 
engine an HPT 1st-stage disk or HPT 2nd-stage disk that does not 
meet the definition of a part eligible for installation in paragraph 
(h)(1) of this AD.

(k) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, ECO 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
