46706 Federal Register / Vol. 91, No. 141 / Friday, July 24, 2026 / Rules and Regulations also determined that this action is an Executive Order 14192 deregulatory action. B. Regulatory Flexibility Act Pursuant to section 605(b) of the Regulatory Flexibility Act (5 U.S.C. 601 et seq. ), FCA hereby certifies that the rule will not have a significant economic impact on a substantial number of small entities. Each of the banks in the Farm Credit System, considered together with its affiliated associations, has assets and annual income more than the amounts that would qualify them as small entities. Therefore, Farm Credit System institutions are not ‘‘small entities’’ as defined in the Regulatory Flexibility Act. C. Congressional Review Act Under the provisions of the Congressional Review Act (5 U.S.C. 801 et seq. ), OIRA has determined that this final rule is not a ‘‘major rule’’ as the term is defined at 5 U.S.C. 804(2).

Airplanes AGENCY : Federal Aviation Administration (FAA), DOT. ACTION : Final rule; request for comments. SUMMARY : The FAA is adopting a new airworthiness directive (AD) for certain Textron Aviation Inc. (Textron) Model B300 and B300C airplanes. This AD was prompted by the manufacturer’s revision of the airworthiness limitations manual (ALM) to introduce revised inspection intervals to detect cracks in the wing spar or wing supporting structure. This AD requires revising the Airworthiness Limitations section (ALS) of the existing aircraft maintenance manual (AMM) or instructions for continued airworthiness (ICA) and the existing approved maintenance or inspection program, as applicable. The FAA is issuing this AD to address the unsafe condition on these products. DATES : This AD is effective August 10, 2026. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of August 10, 2026. The FAA must receive comments on this AD by September 8, 2026. ADDRESSES : You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to regulations.gov.

46707 Federal Register / Vol. 91, No. 141 / Friday, July 24, 2026 / Rules and Regulations will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this AD. Submissions containing CBI should be sent to Soban Saeed, Aviation Safety Engineer, FAA, 1801 South Airport Road, Wichita, KS 67209. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA was notified by Textron that the existing ALM of the ICA for Textron Model B300 and B300C airplanes contained incorrect wing inspection intervals for airplanes that are certified to or operating at a 16,500 pound (lb.) maximum takeoff weight (MTOW). As a result, Textron has revised the existing Model B300 and B300C structural inspection and repair manual (SIRM) and ALM to separate the wing inspection criteria and intervals between airplanes that are certified to or operating at a 15,000 lb. MTOW and those that are certified to or operating at a 16,500 MTOW. The new and updated inspection criteria are based upon the airplane operating hours. The FAA is issuing this AD to prevent undetected cracks in the wing or wing supporting structure. The unsafe condition, if not addressed, could result in reduced structural integrity and consequent wing separation from the fuselage in flight. FAA’s Determination The FAA is issuing this AD because the agency determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed Textron Mandatory Service Letter MTL–57–04, Revision 1, dated March 27, 2025. This material specifies information about the new and updated wing inspection criteria for Model B300 and B300C airplanes within the SIRM and ALM based upon the airplane operating hours. 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. AD Requirements This AD requires revising the ALS of the existing AMM or ICA and the existing approved maintenance or inspection program, as applicable, by incorporating the actions and associated intervals specified in the material already described. Justification for Immediate Adoption and Determination of the Effective Date Section 553(b) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq. ) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for ‘‘good cause,’’ finds that those procedures are ‘‘impracticable, unnecessary, or contrary to the public interest.’’ Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause. An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies forgoing notice and comment prior to adoption of this rule because the existing incorrect wing inspection intervals need to be revised to detect any crack that could develop in the wing spar or wing supporting structure due to differences in operators’ mission profiles (airplanes operating at a 16,500 lb. MTOW). Current FAA data indicate that a number of airplanes are past the revised inspection intervals specified in this AD. Cracks in the wing spar or wing supporting structure could result in reduced structural integrity and consequent wing separation from the fuselage in flight. Additionally, the compliance time in this AD is shorter than the time necessary for the public to comment and for publication of the final rule. Accordingly, notice and opportunity for prior public comment are impracticable and contrary to the public interest pursuant to 5 U.S.C. 553(b). In addition, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days, for the same reasons the FAA found good cause to forgo notice and comment. Regulatory Flexibility Act The requirements of the Regulatory Flexibility Act (RFA) do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because FAA has determined that it has good cause to adopt this rule without prior notice and comment, RFA analysis is not required. Costs of Compliance The FAA estimates that this AD affects 113 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: E STIMATED C OSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Revise the ALS ........................... 1 work-hours × $85 per hour = $85 ................................................. $0 $85 $9,605 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: VerDate Sep<11>2014 15:52 Jul 23, 2026 Jkt 268001 PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 E:\FR\FM\24JYR1.SGM 24JYR1 khammond on DSK9W7S144PROD with RULES
