Download as PDF Federal Register / Vol. 86, No. 179 / Monday, September 20, 2021 / Proposed Rules § 39.13 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 determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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, I certify this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

Any commentary that the FAA receives that is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA issued an NPRM to amend 14 CFR part 39 by adding an AD that would apply to 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. The NPRM published in the Federal Register on April 10, 2020 (85 FR 20216). The NPRM was prompted by the manufacturer revising the engine TLM life limits of certain critical rotating parts and DAC data files. In the NPRM, the FAA proposed to require operators to revise the airworthiness limitation section (ALS) of their approved aircraft maintenance program (AMP) by incorporating the revised tasks of the applicable TLM for each affected model turbofan engine. Actions Since the NPRM Was Issued Since the FAA issued the NPRM, RRD has revised the tasks of the TLM for affected engines, updating the life limits of certain critical rotating parts and updating the DAC data files. RRD published Rolls-Royce Trent 1000 TLM T-Trent-10RRC, Chapters 05–10 and 05– 20, Revision 20, both dated August 1, 2020. Additionally, since the FAA issued the NPRM, EASA, which is the Technical Agent for the Member States of the European Union, superseded AD 2019–0058R1, dated April 2, 2019, with AD 2020–0241, dated November 5, 2020 (EASA AD 2020–0241), to require updates to the life limits and the DAC data files for affected engines. Comments The FAA received one comment on the NPRM from The Boeing Company (Boeing). The agency considered the comment received. Boeing supported the NPRM without change. FAA’s Determination These engines 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 the State of Design Authority, the FAA has been notified about the unsafe condition described in the EASA AD referenced in E:\FR\FM\20SEP1.SGM 20SEP1 52113 Federal Register / Vol. 86, No. 179 / Monday, September 20, 2021 / Proposed Rules this proposed AD. The FAA is issuing this SNPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Certain changes described above expand the scope of the NPRM. As a result, it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this SNPRM. 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 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. Proposed AD Requirements in This SNPRM This proposed AD would require accomplishing the actions specified in EASA AD 2020–0241, 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.’’ Explanation of Required Compliance Information In the FAA’s ongoing efforts to improve the efficiency of the AD process, the FAA initially worked with Airbus and EASA to develop a process to use certain EASA ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has since coordinated with other manufacturers and civil aviation authorities (CAAs) to use this process. As a result, the FAA proposes to incorporate EASA AD 2020–0241 in the FAA final rule. This proposed AD would require compliance with EASA AD 2020–0241 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in EASA AD 2020–0241 does not mean that operators need comply only with that section. For example, where the AD requirement refers to ‘‘all required actions and compliance times,’’ compliance with this AD requirement is not limited to the section titled ‘‘Required Action(s) and Compliance Time(s)’’ in EASA AD 2020–0241. Service information specified in EASA AD 2020–0241 that is required for compliance with it will be available at https://www.regulations.gov by searching for and locating Docket No. FAA–2020–0364 after the FAA final rule is published. Differences Between This Proposed AD and the EASA AD This AD does not mandate the ‘‘Maintenance Tasks and Replacement of Critical Parts’’ and ‘‘Corrective Action(s)’’ sections of EASA AD 2020– 0241. Where EASA AD 2020–0241 requires compliance from its effective date, this proposed AD requires using the effective date of this AD. Where EASA AD 2020–0241 requires operators revising the approved AMP within 12 months from its effective date, this proposed AD requires revising the approved AMP within 90 days after the effective date of this AD. This AD does not mandate compliance with the ‘‘Remarks’’ section of EASA AD 2020– 0241. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 20 engines installed on airplanes of U.S. Registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Revise the AMP .............................................. 1 work-hour × $85 per 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. VerDate Sep<11>2014 15:49 Sep 17, 2021 Jkt 253001 Cost per product Parts cost $0 Cost on U.S. operators $85 $1,700 Regulatory Findings List of Subjects in 14 CFR Part 39 The FAA determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

ACTION: Supplemental notice of proposed rulemaking (SNPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA is revising a notice of proposed rulemaking (NPRM) 
that applied to 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 action revises the 
NPRM by requiring revision of the engine Time Limits Manual (TLM) life 
limits of certain critical rotating parts and direct accumulation 
counting (DAC) data files, as specified in a European Union Aviation 
Safety Agency (EASA) AD, which is proposed for incorporation by 
reference (IBR). The FAA is proposing this AD to address the unsafe 
condition on these products. Since these actions would impose an 
additional burden over those in the NPRM, the agency is requesting 
comments on this SNPRM.

DATES: The FAA must receive comments on this SNPRM by November 4, 2021.

ADDRESSES: You may send comments, using the procedures found in 14 CFR

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this SNPRM contain 
commercial or financial information that is customarily treated as 
private, that you actually treat as private, and that is relevant or 
responsive to this SNPRM, it is important that you clearly designate 
the submitted comments as CBI. Please mark each page of your submission 
containing CBI as ``PROPIN.'' The FAA will treat such marked 
submissions as confidential under the FOIA, and they will not be placed 
in the public docket of this SNPRM. Submissions containing CBI should 
be sent to Kevin M. Clark, Aviation Safety Engineer, ECO Branch, FAA, 
1200 District Avenue, Burlington, MA 01803. Any commentary that the FAA 
receives that is not specifically designated as CBI will be placed in 
the public docket for this rulemaking.

Background

    The FAA issued an NPRM to amend 14 CFR part 39 by adding an AD that 
would apply to 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. The NPRM published in the Federal Register on April 10, 2020 
(85 FR 20216). The NPRM was prompted by the manufacturer revising the 
engine TLM life limits of certain critical rotating parts and DAC data 
files. In the NPRM, the FAA proposed to require operators to revise the 
airworthiness limitation section (ALS) of their approved aircraft 
maintenance program (AMP) by incorporating the revised tasks of the 
applicable TLM for each affected model turbofan engine.

Actions Since the NPRM Was Issued

    Since the FAA issued the NPRM, RRD has revised the tasks of the TLM 
for affected engines, updating the life limits of certain critical 
rotating parts and updating the DAC data files. RRD published Rolls-
Royce Trent 1000 TLM T-Trent-10RRC, Chapters 05-10 and 05-20, Revision 
20, both dated August 1, 2020.
    Additionally, since the FAA issued the NPRM, EASA, which is the 
Technical Agent for the Member States of the European Union, superseded 
AD 2019-0058R1, dated April 2, 2019, with AD 2020-0241, dated November 
5, 2020 (EASA AD 2020-0241), to require updates to the life limits and 
the DAC data files for affected engines.

Comments

    The FAA received one comment on the NPRM from The Boeing Company 
(Boeing). The agency considered the comment received. Boeing supported 
the NPRM without change.

FAA's Determination

    These engines 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 the State of Design 
Authority, the FAA has been notified about the unsafe condition 
described in the EASA AD referenced in

[[Page 52113]]

this proposed AD. The FAA is issuing this SNPRM after determining that 
the unsafe condition described previously is likely to exist or develop 
on other products of the same type design. Certain changes described 
above expand the scope of the NPRM. As a result, it is necessary to 
reopen the comment period to provide additional opportunity for the 
public to comment on this SNPRM.

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 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.

Proposed AD Requirements in This SNPRM

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2020-0241, 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.''

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA initially worked with Airbus and EASA to develop a 
process to use certain EASA ADs as the primary source of information 
for compliance with requirements for corresponding FAA ADs. The FAA has 
since coordinated with other manufacturers and civil aviation 
authorities (CAAs) to use this process. As a result, the FAA proposes 
to incorporate EASA AD 2020-0241 in the FAA final rule. This proposed 
AD would require compliance with EASA AD 2020-0241 in its entirety 
through that incorporation, except for any differences identified as 
exceptions in the regulatory text of this proposed AD. Using common 
terms that are the same as the heading of a particular section in EASA 
AD 2020-0241 does not mean that operators need comply only with that 
section. For example, where the AD requirement refers to ``all required 
actions and compliance times,'' compliance with this AD requirement is 
not limited to the section titled ``Required Action(s) and Compliance 
Time(s)'' in EASA AD 2020-0241. Service information specified in EASA 
AD 2020-0241 that is required for compliance with it will be available 
at https://www.regulations.gov by searching for and locating Docket No. 
FAA-2020-0364 after the FAA final rule is published.

Differences Between This Proposed AD and the EASA AD

    This AD does not mandate the ``Maintenance Tasks and Replacement of 
Critical Parts'' and ``Corrective Action(s)'' sections of EASA AD 2020-
0241. Where EASA AD 2020-0241 requires compliance from its effective 
date, this proposed AD requires using the effective date of this AD. 
Where EASA AD 2020-0241 requires operators revising the approved AMP 
within 12 months from its effective date, this proposed AD requires 
revising the approved AMP within 90 days after the effective date of 
this AD. This AD does not mandate compliance with the ``Remarks'' 
section of EASA AD 2020-0241.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 20 engines installed on airplanes of U.S. Registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

                                                 Estimated Costs

                                         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 determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.
