(d) Process for adding, changing, or removing restrictions. Restrictions on the importation of specific types of cut flowers will be changed through the following processes: (1) Process for removing or relaxing restrictions. (i) If APHIS determines that the requirements for the importation of a specific type of cut flower are no longer necessary to reasonably mitigate the pest risk posed by the cut flower, APHIS will publish a notice in the Federal Register proposing to revise the requirements for the importation of the cut flower. The notice will also make the new pest risk documentation on which these proposed requirements are based available for public comment. The notice will allow for at least 60 days of public comment. (ii) APHIS will issue a second notice after the close of the public comment period on the notice described in paragraph (d)(1)(i) of this section. This notice will inform the public of APHIS’ decision whether to remove or relax requirements for the importation of the cut flower, and it will respond to any comments received on the initial notice. (2) Process for adding restrictions. (i) If APHIS determines that the requirements for the importation of a specific type of cut flower are no longer sufficient to reasonably mitigate the pest risk posed by the cut flower, APHIS will prohibit or further restrict importation of the cut flower. APHIS will also publish a notice in the Federal Register advising the public of its finding. The notice will specify the amended importation requirements, provide an effective date for the change, and will invite public comment on the subject. The notice will allow for at least 60 days of public comment. (ii) APHIS will issue a second notice after the close of the public comment period on the notice described in paragraph (d)(2)(i) of this section. This notice will inform the public of APHIS’ decision whether to add requirements for the importation of the cut flower, and it will respond to any comments received on the initial notice. (e) Previously imposed restrictions on the importation of specific types of cut flowers. Types of cut flowers whose importation was subject to specific restrictions as of November 9, 2026, will continue to be subject to those restrictions, except as changed in accordance with the process specified in paragraph (d) of this section. The restrictions are found in the USDA Agricultural Commodity Import Requirements database. * * * * * (Approved by the Office of Management and Budget under control number 0579–0049) Done in Washington, DC, this 29th day of September 2026.

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 received a report that an Airbus Model A380 airplane equipped with EA Model GP7270 engines experienced an uncontained failure of the HPT interstage seal that resulted in an engine shutdown and aborted takeoff. A manufacturer investigation determined that cracking most likely initiated at the clocking keys between the HPT interstage seal and the HPT stage-1 disk aft shaft. Although the root cause is still under investigation, HPT interstage mid-seal clocking has been identified as a contributing factor for the failure, and the manufacturer has noted that clocking is greater on HPT interstage seals that have been reassembled at overhaul. As a result, the FAA has determined that it is necessary to require removal of the 15 HPT interstage seals with the highest cycles since overhaul. This condition, if not addressed, could result in an engine fire and damage to the airplane. The FAA is issuing this AD to address the unsafe condition on these products. 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 EA Alert Service Bulletin EAGP7–A72–479, dated September 4, 2026, which specifies the affected engine serial numbers, affected HPT interstage seal part numbers, and procedures for removal from service and replacement of the HPT interstage seal. 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 accomplishing the actions specified in the material described previously. Interim Action The FAA considers this AD to be an interim action. If final action is later identified, the FAA might consider further rulemaking at that time. 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 uncontained failure of the HPT interstage seal has been reported with clocking of the HPT interstage seal as a contributing factor. Uncontained failure of the HPT interstage seal could result in an engine fire and damage to the airplane. The clocking was determined to be greater on HPT interstage seals that were re-assembled during overhaul, and the FAA has determined that certain affected engines will need to have the HPT interstage seals removed and replaced within 50 flight cycles or within 30 days after effective date of this AD, whichever occurs first, depending on the serial number. 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.

64258 Federal Register / Vol. 91, No. 194 / Thursday, October 8, 2026 / Rules and Regulations 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 0 engines installed on 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 Replace HPT interstage seal .................. 10 work-hours × $85 per hour = $850 ................................ $527,300 $528,150 $0 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, and (2) Will not affect intrastate aviation in Alaska.

ACTION : Final rule. SUMMARY : The FAA is superseding Airworthiness Directive (AD) 2019–20– 07, which applied to The Boeing Company Model 787–8, 787–9, and 787–10 airplanes. AD 2019–20–07 required repetitive operational checks of the leading edge (LE) outboard (OB) slats and applicable on-condition actions. AD 2019–20–07 also required revising the airplane flight manual (AFM) to prohibit flap retraction under icing conditions after landing and revising the existing maintenance or inspection program, as applicable, to incorporate a new operation check. This AD was prompted by the manufacturer developing further actions to address the unsafe condition. This AD continues to require all requirements of AD 2019– 20–07. This AD would also require replacing the LE outboard geared rotary actuator (GRA) with a LE outboard lockout actuator (LEOLA) at leading edge OB slat locations and revising the existing maintenance or inspection program, as applicable, to incorporate a new certification maintenance requirement (CMR), which terminates the retained requirements of AD 2019– 20–07. This AD also removes airplanes from the applicability. The FAA is issuing this AD to address the unsafe condition on these products. DATES : This AD is effective November 12, 2026. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of November 12, 2026. The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of October 11, 2019 (84 FR 54765, October 11, 2019).

FOR FURTHER INFORMATION CONTACT : Emanuel Chaves Torres, Aviation Safety Engineer, FAA, 2200 South 216th St., Des Moines, WA 98198; phone: 562– 627–5350; email: emanuel.chaves.torres@faa.gov. SUPPLEMENTARY INFORMATION : Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2019–20–07, Amendment 39–19760 (84 FR 54765, October 11, 2019) (AD 2019–20–07). AD 2019–20–07 applied to all The Boeing Company Model 787–8, 787–9, and 787–10 airplanes. The NPRM was published in the Federal Register on March 18, 2026 (91 FR 12942). The NPRM was prompted by the manufacturer developing further actions to address the unsafe condition. In the NPRM, the FAA proposed to continue to require all requirements of AD 2019– 20–07. The NPRM also proposed to require replacing the LE outboard GRA with a LEOLA at leading edge OB slat locations and revising the existing maintenance or inspection program, as applicable, to incorporate a new CMR. The NPRM also proposed to remove airplanes from the applicability. The FAA is issuing this AD to address a potential condition in which the LE OB slat system could be out of position without flight deck annunciation. The unsafe condition, if not addressed, could result in insufficient lift, resulting in inability to maintain continued safe flight and landing. Discussion of Final Airworthiness Directive Comments The FAA received comments from the Air Line Pilots Association, International (ALPA) and United Airlines who supported the NPRM without change. The FAA received additional comments from Boeing. The following presents the comments received on the NPRM and the FAA’s response to each comment. Request To Clarify That the New Requirements Terminate AD 2019–20– 07 Boeing requested a revision to the Summary section of the proposed AD to specify that the new proposed actions would terminate the requirements of AD 2019–20–07. The FAA agrees and has revised the Summary section of this AD accordingly. Request To Clarify Timing of Flap Retraction Prohibition Boeing requested a revision to the Summary and Background sections and the heading to paragraph (i) of the proposed AD to clarify that flap retraction is prohibited under icing conditions ‘‘after landing.’’ The FAA agrees that the AFM provision prohibits flap retraction under icing conditions after landing and has revised the Summary section accordingly. However, no other changes to this AD are necessary because the VerDate Sep<11>2014 15:51 Oct 07, 2026 Jkt 271001 PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 E:\FR\FM\08OCR1.SGM 08OCR1 lotter on DSK8BHNXB4PROD with RULES1
