SUPPLEMENTARY INFORMATION: Discussion We issued AD 2018–24–01, Amendment 39–19505 (84 FR 2715, February 8, 2019), (‘‘AD 2018–24–01’’), for all IAE PW1133G–JM, PW1133GA– JM, PW1130G–JM, PW1127G–JM, PW1127GA–JM, PW1127G1–JM, PW1124G–JM, PW1124G1–JM, and PW1122G–JM turbofan engines with certain LPT 1st- and 3rd-stage disks installed. AD 2018–24–01 required removing certain LPT 1st- and 3rd-stage disks from service and replacing with a part eligible for installation. AD 2018– 24–01 resulted from by a report of manufacturing defects found on delivered LPT 1st- and 3rd-stage disks. We issued AD 2018–24–01 to prevent failure of the LPT 1st- or 3rd-stage disk. PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 Actions Since AD 2018–24–01 Was Issued Since we issued AD 2018–24–01, we learned of incorrect and omitted serial numbers for LPT 1st-stage and 3rd-stage disks in AD 2018–24–01. Two serial numbers, LLDLAJ4594 and LLDLAJ4595, were identified incorrectly, respectively, as LLDLAJ4494 and LLDLAJ4495 in Figure 1 to Paragraph (g) of AD 2018–24–01. In addition, one serial number, LLDLAJ6115, was included in the NPRM but inadvertently omitted from Figure 2 to Paragraph (g) of AD 2018– 24–01. We are issuing this AD to address the unsafe condition on these products. FAA’s Determination We are issuing this AD because we 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 removing certain LPT 1st- and 3rd-stage disks from service and replacing with a part eligible for installation. FAA’s Justification and Determination of the Effective Date No domestic operators use this product.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued AD 2018-24-01, Amendment 39-19505 (84 FR 2715, February 
8, 2019), (``AD 2018-24-01''), for all IAE PW1133G-JM, PW1133GA-JM, 
PW1130G-JM, PW1127G-JM, PW1127GA-JM, PW1127G1-JM, PW1124G-JM, PW1124G1-
JM, and PW1122G-JM turbofan engines with certain LPT 1st- and 3rd-stage 
disks installed. AD 2018-24-01 required removing certain LPT 1st- and 
3rd-stage disks from service and replacing with a part eligible for 
installation. AD 2018-24-01 resulted from by a report of manufacturing 
defects found on delivered LPT 1st- and 3rd-stage disks. We issued AD 
2018-24-01 to prevent failure of the LPT 1st- or 3rd-stage disk.

Actions Since AD 2018-24-01 Was Issued

    Since we issued AD 2018-24-01, we learned of incorrect and omitted 
serial numbers for LPT 1st-stage and 3rd-stage disks in AD 2018-24-01. 
Two serial numbers, LLDLAJ4594 and LLDLAJ4595, were identified 
incorrectly, respectively, as LLDLAJ4494 and LLDLAJ4495 in Figure 1 to 
Paragraph (g) of AD 2018-24-01. In addition, one serial number, 
LLDLAJ6115, was included in the NPRM but inadvertently omitted from 
Figure 2 to Paragraph (g) of AD 2018-24-01. We are issuing this AD to 
address the unsafe condition on these products.

FAA's Determination

    We are issuing this AD because we 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 removing certain LPT 1st- and 3rd-stage disks from 
service and replacing with a part eligible for installation.

FAA's Justification and Determination of the Effective Date

    No domestic operators use this product. Therefore, we find good 
cause that notice and opportunity for prior public comment are 
impracticable. In addition, for the reason stated above, we find that 
good cause exists 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 we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
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-2018-0735 and product identifier 
2018-NE-26-AD at the beginning of your comments. We specifically invite 
comments on the overall regulatory, economic, environmental, and energy 
aspects of this final rule. We will consider all comments received by 
the

    We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this final rule.

Costs of Compliance

    We estimate that this AD affects 0 engines installed on airplanes 
of U.S. registry.
    We estimate the following costs to comply with this AD:

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.
    We are 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to engines, propellers, and 
associated appliances to the Manager, Engine and Propeller Standards 
Branch, Policy and Innovation Division.

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,
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
