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 Pilatus Model PC–12/ 47E airplanes. The NPRM was published in the Federal Register on March 19, 2026 (91 FR 13240). The NPRM was prompted by AD 2025–0271, dated December 2, 2025 (EASA AD 2025–0271) (also referred to as the MCAI), issued by EASA, which is the Technical Agent for the Member States of the European Union. The MCAI states that during a test flight on a Pilatus Model PC–12/47E airplane in which the airplane flew specific maneuvers where gravitational loads (g-loads) were close to 0 g, during landing with flaps at 40 degrees, the SWPS triggered at a higher- than-expected airspeed, including the aural warning, stick shaker, and stick pusher. This same software is on the delivered airplanes that are affected by this AD. This condition, if not addressed, could result in reduced safety margins of the airplane, increased pilot workload, and reduced control of the airplane. In the NPRM, the FAA proposed to require updating operational software and incorporating a POH TR. The NPRM also proposed to prohibit the installation of affected software, as specified in EASA AD 2025–0271. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2026–2715. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs. Conclusion These products have been approved by the civil 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, that authority has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA reviewed the relevant data, considered any comments 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. This AD is adopted as proposed in the NPRM. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed EASA AD 2025– 0271, which specifies procedures for updating the Honeywell Primus APEX operational software, and for incorporating Pilatus PC–12/47E POH TR No. 32 into the POH. EASA AD 2025–0271 also allows for the incorporation of a later POH revision that includes the same POH amendment content and prohibits the installation of affected software. 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 the ADDRESSES section. Costs of Compliance The FAA estimates that this AD affects 265 airplanes of U. S. registry. The FAA estimates the following costs to comply with this AD: VerDate Sep<11>2014 15:59 Jun 08, 2026 Jkt 268001 PO 00000 Frm 00028 Fmt 4700 Sfmt 4700 E:\FR\FM\09JNR1.SGM 09JNR1 lotter on DSK8BHNXB4PROD with RULES1

34753 Federal Register / Vol. 91, No. 110 / Tuesday, June 9, 2026 / Rules and Regulations E STIMATED C OSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Update software ......................... 3 work-hours × $85 per hour = $255 .............................................. $0 $255 $67,575 Revise POH ............................... 1 work-hour × $85 per hour = $85 ................................................. 0 85 22,525 The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators. 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 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

34754 Federal Register / Vol. 91, No. 110 / Tuesday, June 9, 2026 / Rules and Regulations 1 The language being discussed originally was codified at 21 U.S.C. 823(g). It was redesignated as 21 U.S.C. 823(h) by the Medical Marijuana and Cannabidiol Research Expansion Act, 117 Public Law 215 § 103 (2022). 2 This requirement was incorporated into the CSA by the Narcotic Treatment Act of 1974 (NATA), 93 P.L. 281 § 3 (1974). 3 21 U.S.C. 802(29) defines maintenance treatment as the dispensing, for a period in excess of twenty-one days, of a narcotic drug in the treatment of an individual for dependence upon heroin or other morphine-like drugs. 4 21 U.S.C. 802(30) defines detoxification treatment as the dispensing, for a period not in excess of one hundred and eighty days, of a narcotic drug in decreasing doses to an individual in order to alleviate adverse physiological or psychological effects incident to withdrawal from the continuous or sustained use of a narcotic drug and as a method of bringing the individual to a narcotic drug-free state within such period. 5 DEA notes that the SUPPORT for Patients and Communities Reauthorization Act of 2025 (Pub. L. 119–44) became law on December 1, 2025, which includes an additional flexibility to allow delivery of a controlled substance by a pharmacy to a practitioner. This provision will be implemented in a future rulemaking. 6 On October 17, 2000, Congress passed the Drug Addiction Treatment Act of 2000 (DATA), amending the CSA to establish ‘‘waiver authority for physicians who dispense or prescribe certain narcotic drugs for maintenance treatment or detoxification treatment.’’ Public Law 106–310, title XXXV; 114 Stat. 1222. Prior to DATA, the CSA and DEA regulations required practitioners who wanted to conduct maintenance or detoxification treatment using any narcotic controlled drugs to be registered as a Narcotic Treatment Program (NTP) in addition to the practitioner’s personal registration. Hence, the term ‘‘DATA-waiver program’’ is used to describe the process by which individual practitioners (physicians, nurse practitioners, physician assistants, clinical nurse specialists, certified registered nurse anesthetists, and certified nurse midwives) would receive an identification number from DEA, and be exempt from the requirement for separate registration to dispense or prescribe schedule III, IV, or V narcotic controlled drugs approved by the Food and Drug Administration specifically for use in maintenance or detoxification treatment.

[FR Doc. 2026–11528 Filed 6–8–26; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF JUSTICE Drug Enforcement Administration 21 CFR Parts 1300, 1301, and 1306 [Docket No. DEA–499] RIN 1117–AB55 Implementation of the Substance Use- Disorder Prevention That Promotes Opioid Recovery and Treatment for Patients and Communities Act of 2018: Dispensing and Administering Controlled Substances for Medication- Assisted Treatment AGENCY : Drug Enforcement Administration, Department of Justice. ACTION : Final rule. SUMMARY : The ‘‘Substance Use-Disorder Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities Act of 2018 (the SUPPORT Act),’’ which became law on October 24, 2018, amended the Controlled Substances Act to expand the conditions a practitioner must meet to provide medication-assisted treatment for opioid use disorder and expand the options available for a physician to be considered a qualifying physician. The SUPPORT Act also allowed a pharmacy to deliver prescribed controlled substances to a practitioner’s registered location for the purpose of maintenance or detoxification treatment to be administered under certain conditions by a practitioner. The Drug Enforcement Administration promulgated an interim final rule with request for comments in November 2020 to amend its regulations to make them consistent with the SUPPORT Act and implement its requirements. On December 29, 2022, the Restoring Hope for Mental Health and Well-Being Act of 2022 removed many of the statutory provisions of the SUPPORT Act. This final rule adopts the provisions of the interim final rule that are still applicable as final, with minor changes. In addition, this final rule implements the related provisions of the Restoring Hope for Mental Health and Well-Being Act of 2022. DATES : This final rule is effective July 9, 2026.

Achbach, Regulatory Drafting and Policy Support Section (DPW) Diversion Control Division, Drug Enforcement Administration; Mailing Address: 8701 Morrissette Drive, Springfield, Virginia 22152; Telephone: (571) 776–3882. SUPPLEMENTARY INFORMATION : Legal Authority Pertinent Provisions of the SUPPORT Act The Controlled Substances Act (CSA), in 21 U.S.C 823(h), 1 has long mandated that practitioners who dispense narcotic drugs for maintenance or detoxification treatment must obtain an annual separate registration for that purpose 2 and has also provided exceptions to that requirement in a previous iteration. Congress has revised, and then removed, the exceptions over time. Previously, 21 U.S.C. 823(h)(2) set forth the conditions under which a practitioner could, without being separately registered as a Narcotic Treatment Program (NTP), dispense a narcotic drug in Schedule III, IV, or V for the purpose of maintenance treatment 3 or detoxification treatment. 4 On October 24, 2018, the President signed the SUPPORT Act into law as Public Law 115–271. Sections 3201 and 3202 of the SUPPORT Act amended certain provisions of 21 U.S.C. 823(g)(2) [now 823(h)(2)]. 5 Section 3204 of the SUPPORT Act amended the Controlled Substances Act (CSA) by adding section 309A (21 U.S.C. 829a), which sets forth the conditions under which a pharmacy may deliver certain controlled substances to the prescribing practitioner or the practitioner administering the controlled substance (administering practitioner) for the purpose of maintenance or detoxification treatment. All of the changes to the CSA, from these sections of the SUPPORT Act, will be fully described below. Restoring Hope for Mental Health and Well-Being Act of 2022 On December 29, 2022, the President signed the Restoring Hope for Mental Health and Well-Being Act of 2022 into law by way of the Consolidated Appropriations Act, 2023 (hereinafter Omnibus), as title I of Division FF of Public Law 117–328. Section 1262 of the Omnibus amended the CSA by striking section 303(h)(2) (21 U.S.C. 823(h)(2)) in its entirety and striking parts of 303(h)(1) (21 U.S.C. 823(h)(1)), eliminating the DATA-waiver program. 6 Additionally, Section 1263 of the Omnibus added paragraph (m) to section 303 (21 U.S.C. 823), implementing a one-time training requirement for prescribers of controlled VerDate Sep<11>2014 15:59 Jun 08, 2026 Jkt 268001 PO 00000 Frm 00030 Fmt 4700 Sfmt 4700 E:\FR\FM\09JNR1.SGM 09JNR1 lotter on DSK8BHNXB4PROD with RULES1
