{"abstract":"The FAA proposes to supersede Airworthiness Directive (AD) 2018-26-03, which applies to all The Boeing Company Model 757-200 series airplanes. AD 2018-26-03 requires, for the Captain's and First Officer's seats, repetitive horizontal actuator identifications, repetitive checks of the horizontal movement system (HMS), a detailed inspection of the HMS, as applicable, and applicable on-condition actions. AD 2018-26-03 also requires a general visual inspection to determine the seat part numbers of the Captain's and First Officer's seats, a cable adjustment check on seats with certain seat part numbers, and applicable on-condition actions. Since the FAA issued AD 2018-26-03, the FAA has determined that additional seats are affected by the unsafe condition. This proposed AD would retain the actions required by AD 2018-26-03 and add an inspection for previously omitted part numbers. The FAA is proposing this AD to address the unsafe condition on these products.","action":"Notice of proposed rulemaking (NPRM).","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Federal Aviation Administration","name":"Federal Aviation Administration","id":159,"url":"https://www.federalregister.gov/agencies/federal-aviation-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/159","parent_id":492,"slug":"federal-aviation-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2025/03/31/2025-04985.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"90 FR 14213","comment_url":null,"comments_close_on":"2025-05-15","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by May 15, 2025.","disposition_notes":null,"docket_ids":["Docket No. FAA-2025-0473","Project Identifier AD-2024-00281-T"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2025-0473-0011"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2025-0473-0002"}],"agency_name":"FAA","documents":[{"comment_count":7,"comment_start_date":"2025-03-31","updated_at":"2025-05-16T01:55:42.185-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2025-0473-0001","allow_late_comments":false,"id":"FAA-2025-0473-0001","comment_end_date":"2025-05-16","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2025-0473","title":"AD-2024-00281-T; The Boeing Company Model 757-200 series airplanes; the Captain’s and First Officer’s seats"}],"document_number":"2025-04985","effective_on":null,"end_page":14217,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2025/03/31/2025-04985.xml","html_url":"https://www.federalregister.gov/documents/2025/03/31/2025-04985/airworthiness-directives-the-boeing-company-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2025-04985?publication_date=2025-03-31","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2025-03-31/2025-04985/mods.xml","not_received_for_publication":null,"page_length":5,"page_views":{"count":169,"last_updated":"2026-04-04 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2025-03-31/pdf/2025-04985.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2025-04985.pdf?1743165907","publication_date":"2025-03-31","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2025/03/31/2025-04985.txt","regulation_id_number_info":{"2120-AA64":{"issue":"202410","html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202410&RIN=2120-AA64&operation=OPERATION_EXPORT_XML","priority_category":"Routine and Frequent"}},"regulation_id_numbers":["2120-AA64"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2025-0473-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":7,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2025-0473","supporting_documents_count":1,"docket_id":"FAA-2025-0473","document_id":"FAA-2025-0473-0001","regulation_id_number":"2120-AA64","title":"AD-2024-00281-T; The Boeing Company Model 757-200 series airplanes; the Captain’s and First Officer’s seats","checked_regulationsdotgov_at":"2025-05-17T08:55:04Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":14213,"subtype":null,"title":"Airworthiness Directives; The Boeing Company Airplanes","toc_doc":"The Boeing Company Airplanes","toc_subject":"Airworthiness Directives","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":90}
