SUPPLEMENTARY INFORMATION: Background Conclusion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain CFM LEAP–1A23, LEAP–1A24, LEAP–1A24E1, LEAP– 1A26, LEAP–1A26CJ, LEAP–1A26E1, LEAP–1A29, LEAP–1A29CJ, LEAP– 1A30, LEAP–1A32, LEAP–1A33, LEAP– 1A33B2, and LEAP–1A35A model turbofan engines. The NPRM published in the Federal Register on March 23, 2021 (86 FR 15443). The NPRM was prompted by a report of a manufacturing quality escape found during an inspection of an HPT case. In the NPRM, the FAA proposed to require the removal from service of the affected HPT case. The FAA is issuing this AD to address the unsafe condition on these products. The FAA reviewed the relevant data 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. This AD is adopted as proposed in the NPRM. Discussion of Final Airworthiness Directive Costs of Compliance Comments The FAA received no comments on the NPRM or on the determination of the costs. Related Service Information Under 1 CFR Part 51 The FAA reviewed CFM Service Bulletin (SB) LEAP–1A–72–00–0421– 01A–930A–D, Issue 001, dated October 22, 2020. This SB specifies procedures for replacing the affected HPT cases. 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. The FAA estimates that this AD affects 8 engines installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: khammond on DSKJM1Z7X2PROD with RULES ESTIMATED COSTS Action Labor cost Remove and replace the HPT case ............... 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. 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 VerDate Sep<11>2014 15:59 Jun 09, 2021 Jkt 253001 Parts cost 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.

The IFR provided an opportunity for interested persons to submit comments, as well as file a request for hearing or waiver of hearing, on or before November 30, 2020. DEA received three comments and did not receive any requests for hearing or waiver of hearing. Comments Received In response to the IFR, DEA received three comments. The submissions were from individuals or anonymous commenters. One commenter suggested that oliceridine be placed in schedule III rather than schedule II, one commenter had a statement on the controlled name, and the third commenter discussed another substance entirely that was unrelated to oliceridine. As such, the third comment was outside the scope of this current scheduling action. Comment: One commenter suggested that oliceridine be placed in schedule III of the CSA, rather than schedule II. The commenter mentioned that placement of oliceridine in schedule II will limit its medical applications and limit access to the drug due to schedule II manufacturing quotas. The commenter stated that oliceridine has the potential E:\FR\FM\10JNR1.SGM 10JNR1

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 CFM LEAP-1A23, 
LEAP-1A24, LEAP-1A24E1, LEAP-1A26, LEAP-1A26CJ, LEAP-1A26E1, LEAP-1A29, 
LEAP-1A29CJ, LEAP-1A30, LEAP-1A32, LEAP-1A33, LEAP-1A33B2, and LEAP-
1A35A model turbofan engines. The NPRM published in the Federal 
Register on March 23, 2021 (86 FR 15443). The NPRM was prompted by a 
report of a manufacturing quality escape found during an inspection of 
an HPT case. In the NPRM, the FAA proposed to require the removal from 
service of the affected HPT case. The FAA is issuing this AD to address 
the unsafe condition on these products.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the costs.

Conclusion

    The FAA reviewed the relevant data 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. This AD is 
adopted as proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed CFM Service Bulletin (SB) LEAP-1A-72-00-0421-01A-
930A-D, Issue 001, dated October 22, 2020. This SB specifies procedures 
for replacing the affected HPT cases. 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 8 engines installed on 
airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this AD:

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
