Abstract
The FAA is superseding Airworthiness Directive (AD) 2021-26- 13, which applied to all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model 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 engines. AD 2021-26-13 required revision of the engine Time Limits Manual (TLM) life limits of certain critical rotating parts and direct accumulation counting (DAC) data files. Since the FAA issued AD 2021-26-13, RRD has revised the TLM with more restrictive airworthiness limitations, including updated life limits for certain critical parts and updated DAC data files. This AD was prompted by the manufacturer revising the engine TLM life limits of certain critical rotating parts, updating the DAC data files, and updating certain maintenance tasks. This AD requires revising the existing approved maintenance or inspection program, as applicable, to incorporate more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). 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 superseding Airworthiness Directive (AD) 2021-26-
13, which applied to all Rolls-Royce Deutschland Ltd & Co KG (RRD)
Model 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 engines. AD 2021-26-13 required
revision of the engine Time Limits Manual (TLM) life limits of certain
critical rotating parts and direct accumulation counting (DAC) data
files. Since the FAA issued AD 2021-26-13, RRD has revised the TLM with
more restrictive airworthiness limitations, including updated life
limits for certain critical parts and updated DAC data files. This AD
was prompted by the manufacturer revising the engine TLM life limits of
certain critical rotating parts, updating the DAC data files, and
updating certain maintenance tasks. This AD requires revising the
existing approved maintenance or inspection program, as applicable, to
incorporate more restrictive airworthiness limitations, as specified in
a European Union Aviation Safety Agency (EASA) AD, which is
incorporated by reference (IBR). The FAA is issuing this AD to address
the unsafe condition on these products.
DATES: This AD is effective August 15, 2023.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of August 15,
2023.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2021-26-13, Amendment 39-21872 (86 FR
72840, December 23, 2021), (``AD 2021-26-13''). AD 2021-26-13 applied
to all RRD Model 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 engines. AD 2021-26-13
required operators to update the airworthiness limitations section
(ALS) of their approved maintenance and inspection program by
incorporating the latest revision of the engine TLM life limits of
certain critical rotating parts and updating DAC data files for each
affected model engine. The FAA issued AD 2021-26-13 to prevent the
failure of critical rotating parts.
The NPRM published in the Federal Register on March 23, 2023 (88 FR
17426). The NPRM was prompted by EASA AD 2022-0210, dated October 17,
2022 (referred to after this as ``the MCAI''), issued by EASA, which is
the Technical Agent for the Member States of the European Union. The
MCAI states the manufacturer published a revised TLM introducing new or
more restrictive tasks and limitations. These new or more restrictive
tasks and limitations include updating declared lives of certain
critical parts and updating DAC data files.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-0437.
In the NPRM, the FAA proposed to require revising the existing
approved maintenance or inspection program, as applicable, to
incorporate more restrictive airworthiness limitations, as specified in
EASA AD 2022-0210. The FAA is issuing this AD to address the unsafe
condition on these products.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from one commenter, The Boeing Company
(Boeing). Boeing supported the NPRM without change.
Conclusion
These products have been approved by the aviation authority of
another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with this State of Design
Authority, it has notified the FAA of the unsafe condition described in
the MCAI referenced above. 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 NPRM.
Related Service Information Under 1 CFR Part 51
The FAA reviewed EASA AD 2022-0210. EASA AD 2022-0210 specifies
instructions for accomplishing the actions specified in the applicable
TLM, including performing maintenance tasks, replacing life-limited
parts, and revising the existing approved maintenance or inspection
program, as applicable, by incorporating the limitations, tasks, and
associated thresholds and intervals described in the TLM.
This material is reasonably available because the interested
parties have access to it through their normal course
[[Page 44041]]
of business or by the means identified in ADDRESSES.
Differences Between This AD and the MCAI
Where paragraph (3) of EASA AD 2022-0210 specifies revising the
approved Aircraft Maintenance Programme within 12 months after the
effective date of EASA AD 2022-0210, this AD requires revising the ALS
of the existing approved maintenance or inspection program, as
applicable, within 90 days after the effective date of this AD.
Costs of Compliance
The FAA estimates that this AD affects 32 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-hours x $85 per $0 $85 $2,720
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.
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
The FAA has determined that 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.
