{"abstract":"The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes. This AD was prompted by a report of cracking on the radius of the rib 0 forward longeron at a certain frame. This AD requires a one-time inspection for defects of the radius, and repair if necessary. The FAA is issuing this AD to address the unsafe condition on these products.","action":"Final rule.","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/2024/09/30/2024-22319.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"89 FR 79423","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective November 4, 2024.","disposition_notes":null,"docket_ids":["Docket No. FAA-2024-1478","Project Identifier MCAI-2023-01216-T","Amendment 39-22831","AD 2024-17-06"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2024-1478-0004"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2024-1478-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2024-09-30","updated_at":"2024-09-30T09:57:30.510-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2024-1478-0003","allow_late_comments":false,"id":"FAA-2024-1478-0003","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2024-1478","title":"MCAI-2023-01216-T; BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes; cracking on rib 0 forward longeron at frame 26."}],"document_number":"2024-22319","effective_on":"2024-11-04","end_page":79425,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2024/09/30/2024-22319.xml","html_url":"https://www.federalregister.gov/documents/2024/09/30/2024-22319/airworthiness-directives-bae-systems-operations-limited-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2024-22319?publication_date=2024-09-30","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2024-09-30/2024-22319/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":87,"last_updated":"2026-04-04 22:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2024-09-30/pdf/2024-22319.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2024-22319.pdf?1727441135","publication_date":"2024-09-30","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2024/09/30/2024-22319.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-2024-1478-0004"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2024-1478-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":0,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2024-1478","supporting_documents_count":2,"docket_id":"FAA-2024-1478","document_id":"FAA-2024-1478-0003","regulation_id_number":"2120-AA64","title":"MCAI-2023-01216-T; BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes; cracking on rib 0 forward longeron at frame 26.","checked_regulationsdotgov_at":"2024-10-01T12:00:30Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":79423,"subtype":null,"title":"Airworthiness Directives; BAE Systems (Operations) Limited Airplanes","toc_doc":"BAE Systems (Operations) Limited Airplanes","toc_subject":"Airworthiness Directives","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":89}
