{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, and 747SR series airplanes. This proposed AD was prompted by reports of inboard foreflap departures from the airplane. This proposed AD would require repetitive replacement of certain parts; a general visual inspection to determine production configuration for certain parts; a repetitive lubrication of certain parts and a repetitive general visual inspection of certain parts for any exuding grease; repetitive detailed inspections of certain parts for loose or missing attachment bolts, cracks or bushing migration, cracks or gouges, or broken, binding, or missing rollers; repetitive detailed inspections of certain parts for cracks or corrosion; repetitive lubrication; and on-condition actions if necessary. 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/2020/05/18/2020-10539.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"85 FR 29673","comment_url":"https://www.regulations.gov/commenton/FAA-2020-0211-0001","comments_close_on":"2020-07-02","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by July 2, 2020.","disposition_notes":null,"docket_ids":["Docket No. FAA-2020-0211","Product Identifier 2020-NM-006-AD"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2020-0211-0002"}],"agency_name":"FAA","documents":[{"comment_count":6,"comment_start_date":"2020-05-18","updated_at":"2024-11-06T19:17:55.772-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2020-0211-0001","allow_late_comments":true,"id":"FAA-2020-0211-0001","comment_end_date":"2020-07-03","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2020-0211","title":"2020-NM-006-AD"}],"document_number":"2020-10539","effective_on":null,"end_page":29676,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2020/05/18/2020-10539.xml","html_url":"https://www.federalregister.gov/documents/2020/05/18/2020-10539/airworthiness-directives-the-boeing-company-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2020-10539?publication_date=2020-05-18","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2020-05-18/2020-10539/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":307,"last_updated":"2026-09-22 12:15:07 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2020-05-18/pdf/2020-10539.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2020-10539.pdf?1589546742","publication_date":"2020-05-18","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2020/05/18/2020-10539.txt","regulation_id_number_info":{"2120-AA64":{"issue":"202504","html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202504&RIN=2120-AA64&operation=OPERATION_EXPORT_XML","priority_category":"Routine and Frequent"}},"regulation_id_numbers":["2120-AA64"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2020-0211-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":6,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2020-0211","supporting_documents_count":1,"docket_id":"FAA-2020-0211","document_id":"FAA-2020-0211-0001","regulation_id_number":"2120-AA64","title":"2020-NM-006-AD","checked_regulationsdotgov_at":"2024-11-07T23:00:19Z"},"regulations_dot_gov_url":"https://www.regulations.gov/commenton/FAA-2020-0211-0001","significant":false,"signing_date":null,"start_page":29673,"subtype":null,"title":"Airworthiness Directives; The Boeing Company Airplanes","toc_doc":null,"toc_subject":null,"topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":85}
