Abstract
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent 1000-A2, Trent 1000- AE2, Trent 1000-C2, Trent 1000-CE2, Trent 1000-D2, Trent 1000-E2, Trent 1000-G2, Trent 1000-H2, Trent 1000-J2, Trent 1000-K2, and Trent 1000-L2 model turbofan engines. This AD was prompted by the manufacturer revising the engine Time Limits Manual (TLM) life limits of certain critical rotating parts, updating direct accumulation counting (DAC) data files, and updating certain maintenance tasks. This AD requires revision of the engine TLM life limits of certain critical rotating parts and DAC data files, 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.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent 1000-A2, Trent 1000-
AE2, Trent 1000-C2, Trent 1000-CE2, Trent 1000-D2, Trent 1000-E2, Trent
1000-G2, Trent 1000-H2, Trent 1000-J2, Trent 1000-K2, and Trent 1000-L2
model turbofan engines. This AD was prompted by the manufacturer
revising the engine Time Limits Manual (TLM) life limits of certain
critical rotating parts, updating direct accumulation counting (DAC)
data files, and updating certain maintenance tasks. This AD requires
revision of the engine TLM life limits of certain critical rotating
parts and DAC data files, 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.
DATES: This AD is effective January 27, 2022.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of January 27,
2022.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a supplemental notice of proposed rulemaking (SNPRM)
to amend 14 CFR part 39 by adding an AD that would apply to RRD Trent
1000-A2, Trent 1000-AE2, Trent 1000-C2, Trent 1000-CE2, Trent 1000-D2,
Trent 1000-E2, Trent 1000-G2, Trent 1000-H2, Trent 1000-J2, Trent 1000-
K2, and Trent 1000-L2 model turbofan engines. The SNPRM published in
the Federal Register on September 20, 2021 (86 FR 52111). The SNPRM was
prompted by the manufacturer revising the engine TLM life limits of
certain critical rotating parts, updating DAC data files, and updating
certain maintenance tasks. The SNPRM proposed to require operators to
revise the ALS of their approved maintenance program by incorporating
the revised tasks of the applicable TLM for each affected model
turbofan engine. The SNPRM proposed to require accomplishing the
actions specified in EASA AD 2020-0241, dated November 5, 2020 (also
referred to as the Mandatory Continuing Airworthiness Information, or
the MCAI), as incorporated by reference, except for any differences
identified as exceptions in the regulatory text of the 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.
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2020-0241 to correct an unsafe
condition for all RRD Trent 1000-A2, Trent 1000-AE2, Trent 1000-C2,
Trent 1000-CE2, Trent 1000-D2, Trent 1000-E2, Trent 1000-G2, Trent
1000-H2, Trent 1000-J2, Trent 1000-K2, and Trent 1000-L2 model turbofan
engines.
Discussion of Final Airworthiness Directive
Comments
The FAA received one comment from an individual commenter. The
commenter expressed support for the SNPRM without change, but
incorrectly referenced automotive engines within the rationale for the
support.
Conclusion
The FAA reviewed the relevant data, considered the comment
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, this
AD is adopted as proposed in the SNPRM. 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 2020-0241. EASA AD 2020-0241 requires
accomplishment of the actions specified in RRD's updated TLM for
affected engines as specified in Rolls-Royce Trent 1000 TLM T-Trent-
10RRC, Chapters 05-10 and 05-20, Revision 20, dated August 1, 2020.
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.
Costs of Compliance
The FAA estimates that this AD affects 20 engines installed on
airplanes of U.S. registry.
The FAA estimates the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Revise the continuous airworthiness 1 work-hour x $85 per $0 $85 $1,700
maintenance program. hour = $85.
----------------------------------------------------------------------------------------------------------------
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.[FEDREG][VOL]*[/VOL][NO]*[/NO][DATE]*[/
DATE][RULES][RULE][PREAMB][AGENCY]*[/AGENCY][SUBJECT]*[/SUBJECT][/
PREAMB][SUPLINF][HED]*[/HED]
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:
[[Page 72842]]
(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.

This AD was prompted by the manufacturer revising the engine
Time Limits Manual life limits of certain critical rotating parts,
updating the direct accumulation counting data files, and updating
certain maintenance tasks. The FAA is issuing this AD to prevent the
failure of critical rotating parts. The unsafe condition, if not
addressed, could result in failure of one or more engines, loss of
thrust control, and loss of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Required Actions
Except as specified in paragraph (h) of this AD: Perform all
required actions within the compliance times specified in, and in

effective date, this AD requires using the effective date of this
AD.
(3) Paragraph (3) of EASA AD 2020-0241 specifies revising the
approved airworthiness maintenance program within 12 months after
its effective date, but this AD requires revising the existing
approved continuous airworthiness maintenance program within 90 days
after the effective date of this AD.
(4) This AD does not mandate compliance with the ``Remarks''
section of EASA AD 2020-0241.
(i) No Reporting Requirement
Although the service information referenced in EASA AD 2020-0241
specifies to submit certain information to the manufacturer, this AD
does not include that requirement.
