SUPPLEMENTARY INFORMATION:
Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2021-0217, dated September 23, 2021
(EASA AD 2021-0217), to address an unsafe condition for all RRD Trent
XWB-75, Trent XWB-79, Trent XWB-79B, Trent XWB-84, and Trent XWB-97
model turbofan engines.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2021-15-01, Amendment 39-21648 (86 FR
36487, July 12, 2021), (``AD 2021-15-01''). AD 2021-15-01 applied to
all RRD Trent XWB-75, Trent XWB-79, Trent XWB-79B, Trent XWB-84, and
Trent XWB-97 model turbofan engines. The NPRM published in the Federal
Register on March 28, 2022 (87 FR 17209). The NPRM was prompted by the
manufacturer revising the TLM to introduce new instructions for repairs
to the low-pressure compressor blades and fan blade inspections. In the
NPRM, the FAA proposed to require accomplishing the actions specified
in EASA AD 2021-0217, except for any differences identified as
exceptions in the regulatory text of this AD and except as discussed
under ``Differences Between this Proposed AD and the EASA AD.'' The FAA
is issuing this AD to address the unsafe condition on these products.
See EASA AD 2021-0217 for additional background information.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from two commenters. The commenters were
Air Line Pilots Association, International (ALPA) and Delta Air Lines,
Inc (DAL). The following presents the comments received on the NPRM and
the FAA's response to each comment.
Request To Clarify Recording Requirement
DAL requested that the FAA revise paragraph (h)(6), Exceptions to
EASA AD 2021-0217, of this AD to read as follows: ``This AD does not
require compliance with paragraph (5), Recording AD Compliance, of EASA
AD 2021-0217. This AD also does not require that after revising the
AMP, as required by paragraph (3) of EASA AD 2021-0217, that
accomplishment of individual actions is recorded for demonstration of
AD compliance.'' DAL noted that paragraph (5) of EASA AD 2021-0217
states that it is not necessary to record the accomplishment of
individual actions in order to demonstrate AD compliance. DAL indicated
that the proposed language in paragraph (h)(6) of the NPRM would negate
that action, and make the recording of individual actions a requirement
for AD compliance.
The FAA disagrees with revising paragraph (h)(6) of this final
rule. As stated in this AD, this AD does not require compliance with
paragraph (5), Recording AD Compliance, of EASA AD 2021-0217.
Additionally, this AD does not mandate that operators not comply with
paragraph (5), Recording AD Compliance, of EASA AD 2021-0217. The FAA
notes, for purposes of clarification, that this AD only requires
compliance with paragraph (3) of EASA AD 2021-0217, and that paragraph
(3) of EASA AD 2021-0217 does not specify recording of individual
actions in order to demonstrate AD compliance. The FAA did not change
this AD as a result of this comment.
Request To Incorporate by Reference EASA AD 2021-0217
DAL requested that the FAA add paragraph (k), Material Incorporated
by Reference, to this final rule and include EASA AD 2021-0217 in that
paragraph. DAL noted that using EASA ADs as the primary source of
information for compliance with requirements for corresponding FAA ADs
has improved the efficiency of the FAA's AD process and operator's AD
process. DAL also noted that one of the efficiencies of incorporating
EASA AD 2021-0217 by reference is that the Ref. Publications section
would allow for the use of later approved revisions of the TLM.
The FAA notes that EASA AD 2021-0217 was proposed for incorporation
by reference under 1 CFR part 51 in the NPRM, which lists the material
to be incorporated by reference in this final rule. Additionally, while
not typically included in an NPRM, the ``Material Incorporated by
Reference'' paragraph exists in the final rule published for FAA ADs.
The FAA did not change this AD as a result of the comments.
Support for the AD
ALPA expressed support for the AD as written.
Conclusion
The FAA reviewed the relevant data, considered any comments
received, and determined that air safety requires adopting the AD as
proposed. Accordingly, the FAA is issuing this AD to address the unsafe
condition on these products. Except for minor editorial changes, this
AD is adopted as proposed in the NPRM. None of the changes will
increase the economic burden on any operator.
Related Service Information Under 1 CFR Part 51
The FAA reviewed European Union Aviation Safety Agency (EASA) AD
2021-0217, dated September 23, 2021. EASA AD 2021-0217 describes
actions for the incorporation of revised life limits and updated
mandatory inspection intervals of certain critical rotating parts into
the ALS of the RR Trent XWB TLM, as applicable to each engine model,
and the operator's existing approved AMP. This material is reasonably
available because the interested parties have access to it through
their normal course of business or by the means identified in
ADDRESSES.
Other Related Service Information
The FAA reviewed Rolls-Royce Airworthiness Limitations (Mandatory
parts lives), TRENTXWB-A-05-10-01-00A01-030A-D, Revision 016, dated May
1, 2021, of the Rolls-Royce Trent XWB TLM TRENTXWB-K0680-TIME0-01;
Rolls-Royce Airworthiness Limitations (Mandatory Parts Lives),
TRENTXWB-B-05-10-01-00A01-030A-D, Revision 003, dated April 19, 2021,
of the Rolls-Royce Trent XWB TLM TRENTXWB-K0680-TIME0-01; Rolls-Royce
Airworthiness Limitations (Mandatory inspections), TRENTXWB-A-05-20-01-
00A01-030A-D, Revision 015, dated May 1, 2021, of the Rolls-Royce Trent
XWB TLM TRENTXWB-K0680-TIME0-01; and Rolls-Royce Airworthiness
Limitations (Mandatory inspections), TRENTXWB-B-05-20-01-00A01-030A-D,
Revision 008, dated April 19, 2021, of the Rolls-Royce Trent XWB TLM
TRENTXWB-K0680-TIME0-01. These sections of the TLM specify inspection
intervals and life limits, differentiated by engine model, for critical
rotating parts.
Costs of Compliance
The FAA estimates that this AD affects 30 engines installed on
airplanes of U.S. registry.
The FAA estimates 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.
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,
(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.
