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. 72841 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.

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

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.
