Abstract
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd. & Co KG (RRD) Trent 7000-72 and Trent 7000-72C model turbofan engines. This AD was prompted by the manufacturer revising the engine Time Limits Manual (TLM) life limits of certain critical rotating parts and updating certain maintenance tasks. This AD requires the operator to revise the airworthiness limitation section (ALS) of their existing approved continuous airworthiness maintenance program (CAMP) by incorporating the revised tasks of the applicable TLM for each affected model turbofan engine, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2020-0244, dated November 5, 2020
(EASA AD 2020-0244) (also referred to as the Mandatory Continuing
Airworthiness Information, or the MCAI), to correct an unsafe condition
for all RRD Trent 7000-72 and Trent 7000-72C model turbofan engines.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all RRD Trent 7000-72
and Trent 7000-72C model turbofan engines. The NPRM published in the
Federal Register on August 12, 2021 (86 FR 44316). The NPRM was
prompted by the manufacturer revising the engine TLM life limits of
certain critical rotating parts and updating certain maintenance tasks.
In the NPRM, the FAA proposed to require accomplishing the actions
specified in EASA AD 2020-0244, described previously, as incorporated
by reference, except for any differences identified as exceptions in
the regulatory text of this proposed 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
the MCAI for additional background information.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from three commenters. The commenters
were Air Line Pilots Association, International, The Boeing Company,
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 Add Exception to the Definition of AMP
DAL requested that paragraph (h), Exceptions to EASA AD 2020-0244,
of the proposed rule, be updated to provide an exception to the
definition of the AMP for airplanes operated under FAA regulations. DAL
noted that the EASA AD's definition of an AMP is applicable to an
airplane operated under European Union regulations.
The FAA agrees and has updated paragraph (h)(1) of this AD.
Request To Add Exception for High-Pressure Turbine (HPT) Blade
Inspection
DAL requested that paragraph (h), Exceptions to EASA AD 2020-0244,
of this AD, be updated to provide an exception for the HPT blade visual
inspections in the TLM to make the FAA AD consistent with the most
recent publication of RR Trent 7000 TLM-T-T7000-1RR (the TLM) and with
EASA AD 2021-0169, dated July 19, 2021 (EASA AD 2021-1069). DAL
reasoned that EASA AD 2021-0169 incorporates a life limit of 1,000
flight cycles since new on the HPT blade and explicitly cancels the
inspection intervals defined in the TLM.
The FAA disagrees with adding this exception to paragraph (h) of
this AD. The unsafe condition and corrective actions in EASA AD 2021-
0169 are beyond the scope of this AD. The FAA may consider future
rulemaking in response to EASA AD 2021-0169.
Support for the AD
Air Line Pilots Association, International, and The Boeing Company
supported the AD without change.
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.
Related Service Information Under 1 CFR Part 51
The FAA reviewed EASA AD 2020-0244. EASA AD 2020-0244 specifies
revising the approved AMP by incorporating the limitations, tasks, and
associated thresholds and intervals described in the TLM. 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.
Other Related Service Information
The FAA reviewed Chapter 05-10 of RR Trent 7000 TLM T-T7000-1RR,
dated July 10, 2020. RR Trent 7000 TLM T-T7000-1RR, Chapter 05-10,
identifies the reduced life limits of certain critical rotating parts.
The FAA also reviewed Chapter 05-20 of RR Trent 7000 TLM T-T7000-
1RR, dated July 10, 2020. RR Trent 7000 TLM T-T7000-1RR, Chapter 05-20,
identifies the critical rotating part inspection thresholds and
intervals.

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 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.
