SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all International Aero 
Engines, LLC (IAE LLC) Model PW1122G-JM, PW1124G-JM, PW1124G1-JM, 
PW1127G-JM, PW1127G1-JM, PW1127G1A-JM, PW1127G1B-JM, PW1127GA-JM, 
PW1129G-JM, PW1130G-JM, PW1133G-JM, PW1133GA-JM, PW1428G-JM, PW1428GA-
JM, PW1428GH-JM, PW1431G-JM, PW1431GA-JM, and PW1431GH-JM engines. The 
NPRM was published in the Federal Register on March 28, 2025 (90 FR 
14057). The NPRM wasF prompted by multiple reports of fan blade 
fracture events due to bird strikes. Three of these events resulted in 
an engine under cowl fire or pool fire. In the NPRM, the FAA proposed 
to require removal of one loop cushion clamp from the CP09 tube 
assembly and replacement of the TMS clevis mounts with redesigned TMS 
clevis mounts.
    The FAA is issuing this AD to prevent a fuel leak resulting from a 
fan blade fracture. The unsafe condition, if not addressed, could 
result in an uncontrolled engine fire and damage to the airplane.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from nine commenters. The commenters were

[[Page 1079]]

the Airline Pilots Association, International (ALPA); All Nippon 
Airways (ANA); Delta Air Lines (Delta); Lufthansa Technik AG 
(Lufthansa); PW; ProTech Aero Services Limited (ProTech); United 
Airlines (United); and an individual. The following presents the 
comments received on the NPRM and the FAA's response to each comment.

Support for the NPRM

    ALPA, United, and the individual expressed support for the NPRM.

Request To Define ``Next Engine Shop Visit''

    In the NPRM, the FAA proposed that paragraph (g) would require 
certain parts to be replaced ``at the next engine shop visit.'' 
Lufthansa, Delta, and ANA requested that the FAA refine this term. 
Delta stated that there was no definition of ``engine shop visit'' in 
the NPRM. Lufthansa requested that the FAA specify the type of shop 
visit. Lufthansa stated that during quick-turn shop visits with nose-
down procedure, it is not possible to perform the required 
modification. Lufthansa also noted that the modification requirement 
could have a significant effect on operations that are intended to 
minimize turnaround time, and requested that such types of visits be 
excluded from the rule. ANA indicated that the engine manufacturer's 
recommended maintenance program defines ``shop visit'' as ``whenever an 
engine maintenance opportunity entails separating pairs of major mating 
gas path flanges.'' ANA requested clarification on whether this 
definition of ``shop visit'' from the engine maintenance program is 
applicable.
    The FAA agrees to define ``next engine shop visit,'' however, the 
FAA does not agree to exclude quick-turn shop visits. To clarify, for 
this AD quick-turn shop visits are defined as limited scope and meant 
to target specific engine issues. However, regardless of the reason for 
induction, the FAA considers those quick-turn shop visits to be 
``engine shop visits,'' as defined in paragraph (i) of this final rule. 
Operators may request an alternative method of compliance (AMOC) in 
accordance with the procedures specified in paragraph (k) of this AD, 
provided sufficient data are submitted to substantiate that the AMOC 
would provide an acceptable level of safety. The FAA has revised this 
final rule by including paragraph (i), which includes the definition of 
``engine shop visit.''

Request To Alter Compliance Times

    The individual requested that the FAA account for different 
compliance schedules in relation to this NPRM. The commenter stated 
that the compliance schedule of the required actions could affect 
operators with major operational interruptions and higher maintenance 
costs if additional down time is necessary to comply with this proposed 
AD. Additionally, the commenter encouraged the FAA to work with 
stakeholders to improve the AD, such as by exploring other alternative 
methods of risk reduction or conducting a cost-benefit analysis.
    The FAA disagrees with the request to alter the compliance times of 
this AD. In developing an appropriate compliance time for this action, 
the FAA considered the recommendations from the manufacturer. These 
recommendations included the urgency associated with the unsafe 
condition, the availability of required parts, and the practical aspect 
of accomplishing the required modification within a period of time that 
corresponds to the normal scheduled maintenance for most affected 
operators. In consideration of these items, the FAA has determined that 
the specified compliance times will ensure an acceptable level of 
safety. The NPRM gives all stakeholders and the general public the 
opportunity to comment on the proposed required actions and compliance 
times.
    As to the commenter's other suggestion, the FAA worked with 
industry stakeholders, including the manufacturer, and affected 
operators through the public comment process, to develop this final 
rule. However, any operator may request an AMOC in accordance with the 
procedures specified in paragraph (k) of this AD, provided sufficient 
data are submitted to substantiate that the AMOC would provide an 
acceptable level of safety. The FAA has not changed this AD based on 
this comment.

Request for Different Compliance Times for Engines That Are Not 
Installed

    ProTech stated support for the compliance times for engines that 
are already installed on airplanes. However, ProTech requested that the 
FAA specify a compliance time of ``Within 30 days after the effective 
date of this AD, or at the time of installation on an airplane, 
whichever comes later . . .'' for engines which are not installed on an 
airplane.
    The FAA agrees to clarify the compliance time and has revised 
paragraph (g)(1) of this AD to account for each subset of engines.

Request To Remove Certain Language

    PW requested that the FAA remove ``due to bird strike'' from the 
Summary, Background, and the Unsafe Condition sections.
    The FAA agrees with the request. Although three of the six fan 
blade fracture events were caused by bird strikes, other events can 
fracture a fan blade. The FAA has removed all instances of ``due to 
bird strike'' in this final rule, except for the description of the 
NPRM in the Background section.

Request To Use Updated Service Material

    Delta and ANA requested that the FAA update the required actions to 
refer to an updated revision of the applicable service material. Delta 
stated that the later revision allows operators to reuse certain part-
numbered bolts that are removed, if the bolts pass certain inspection 
requirements. Delta stated that this is based on parts availability. 
Delta also requested the FAA revise the credit for previous actions 
paragraph to include the updated service material.
    ANA stated that the instructions in a certain engine manual do not 
specify the requirement to discard bolt part number MS9716-08 or to 
install new bolts. ANA also stated that if the bolts have passed 
certain inspections and procedures and the required torque was applied, 
these bolts are not required to be discarded. ANA requested that the 
FAA allow certain part-numbered bolts to be reused and not discarded if 
they have passed certain inspections and procedures.
    The FAA agrees to allow certain part-numbered bolts to be reused if 
they have passed certain inspections and procedures. Additionally, 
since the NPRM was published, the manufacturer has released multiple 
revisions to PW Alert Service Bulletin (ASB) PW1000G-C-72-00-0214-00A-
930A-D. The FAA has revised this AD to reference PW ASB PW1000G-C-72-
00-0214-00A-930A-D, Issue 006 as the appropriate source of material and 
has included credit for all previous revisions.

Request To Require Reinstallation of the Loop Cushion Clamp

    Delta requested that the FAA revise the required actions to require 
reinstallation of the loop cushion clamp after replacement of the TMS 
clevis mounts. Delta stated that PW ASB PW1000G-C-72-00-0214-00A-930A-D 
contains a step for reinstalling the loop cushion clamp after the TMS 
clevis mounts have been replaced, which the FAA did not include in the 
NPRM. Delta expressed the expectation that

[[Page 1080]]

since the required steps of the service material include removal of the 
loop cushion clamp, that the intention would also be to reinstall.
    The FAA agrees. However, since the NPRM was published, PW ASB 
PW1000G-C-72-00-0214-00A-930A-D has been updated and the FAA has 
revised this AD to refer to the latest revision of the required 
material. Additionally, the steps contained in the updated material 
have changed, which in turn, caused the steps referenced in this AD to 
change. Accordingly, the FAA has revised paragraph (g)(2) of this AD to 
require the steps in the latest revision of PW ASB PW1000G-C-72-00-
0214-00A-930A-D, which includes reinstalling the loop cushion clamp 
with the redesigned TMS clevis mounts after the TMS clevis mounts are 
replaced.

Request To Revise Terminating Action

    PW requested that the FAA revise the terminating action paragraph 
of the NPRM to specify that the actions specified in paragraph (g)(2) 
of the NPRM constitute a terminating action for the entire NPRM. No 
further justification was provided.
    The FAA disagrees with the request to revise the terminating action 
to apply to the entire AD. The FAA notes that the terminating action 
paragraph of this AD only applies to the removal of the loop cushion 
clamp because once the TMS clevis mounts are replaced, this action is 
no longer necessary. The FAA has not changed this AD based on this 
request.

Request To Change Interim Action to Final Action

    PW requested that the FAA revise the wording of the NPRM to specify 
that the required actions are final and that the NPRM is not considered 
an interim action. PW stated that the TMS clevis mounts replacement and 
subsequent reinstallation of the loop cushion clamp addresses the 
unsafe condition.
    The FAA agrees that the TMS clevis mounts replacement and 
subsequent reinstallation of the loop cushion clamp does address the 
unsafe condition. However, since the FAA has not included the interim 
action paragraph in this final rule, there is no need for the FAA to 
change this final rule based on the request.

Request for Clarification Regarding Removal of the Loop Cushion Clamp

    ANA requested that the FAA revise paragraphs (c) or (g)(1) of the 
NPRM to include an exemption for engines that have already complied 
with ASB PW1000G-C-72-00-0214-00A-930A-D. ANA requested clarification 
whether engines that have replaced the TMS clevis mounts are also 
required to remove the loop cushion clamp. ANA stated that even though 
the terminating action removes the requirement to remove the loop 
cushion clamp, there is still possibility for confusion for the 
operator, which may accidentally do both actions.
    The FAA agrees to clarify. The replacement of the TMS clevis mounts 
specified in paragraph (g)(2) of this AD terminates the loop clamp 
removal specified in paragraph (g)(1) of this AD. As discussed 
previously in this final rule, the FAA has also included reinstallation 
of the loop clamp as an additional requirement to paragraph (g)(2) of 
this AD and as such, there is no need to include the language suggested 
by the commenter. Furthermore, paragraph (f) of this AD states to 
accomplish the required actions within the compliance times specified, 
``unless already done.'' Therefore, if operators have accomplished the 
actions required for compliance with this AD before the effective date 
of this AD, no further action is necessary. The FAA has not revised 
this AD in this regard.

Conclusion

    The FAA reviewed the relevant data, considered any comments 
received, and determined that air safety requires adopting this AD as 
proposed. Accordingly, the FAA is issuing this AD to address the unsafe 
condition on these products. Except for minor editorial changes, and 
any other changes described previously, this AD is adopted as proposed 
in the NPRM. None of the changes will increase the economic burden on 
any operator.

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

[[Page 1081]]

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,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) 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.
