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 PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 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 regulations.gov 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.

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. 44041 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 Action Labor cost Parts cost Cost per product Cost on U.S. operators Revise the continuous airworthiness maintenance program. 1 work-hours × $85 per hour = $85 $0 $85 $2,720 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. ddrumheller on DSK120RN23PROD with RULES1 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.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Bombardier, Inc., Model BD–100–1A10 airplanes. The NPRM published in the Federal Register on January 12, 2023 (88 FR 2029). The NPRM was prompted by AD CF–2022– 28, dated May 26, 2022, issued by Transport Canada, which is the aviation authority for Canada (referred to after this as the MCAI). The MCAI states there have been multiple reports of erratic electrical system status on the PBAs and the EICAS while on-ground and during flight, and in several cases, leading to momentary loss of electrical power and loss of flight displays following flight crew responses to the erratic statuses. It was found that airplanes could experience misleading electrical system status indications (PBA and EICAS) as a result of contamination of electrical contacts in the LH DCPC internal communication data bus. Those erratic indications could cause the crew to turn off fullyoperational electrical power sources, leading to partial or complete loss of electrical power. Loss of electrical power could result in the loss of flight displays and reduced controllability of the airplane. The MCAI also states that Transport Canada previously issued AD CF–2020– 46, dated November 17, 2020 (which corresponds to FAA AD 2021–23–14, Amendment 39–21812 (86 FR 68889, December 6, 2021)), which mandated the use of revised Electrical Emergency and Non-Normal Procedures in the airplane flight manual that directed crews not to turn off active generators in the event of an erroneous electrical system status indication. The MCAI advised that further corrective action is being developed to introduce a design improvement to the DCPC that is intended to protect the internal communication data bus from contaminants, and that a time-limited maintenance check will also be implemented. In the NPRM, the FAA proposed to require a records check and replacement E:\FR\FM\11JYR1.SGM 11JYR1

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 regulations.gov 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

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.
