{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation (Gulfstream) Model GVII- G500 airplanes. This proposed AD results from flap yoke fittings with design features that cause decreased fatigue life. This proposed AD would require replacing the flap inboard and outboard yoke fitting assemblies and establishing a 20,000 flight cycle life limit for the fittings. 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/2021/05/07/2021-09243.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"86 FR 24546","comment_url":"https://www.regulations.gov/commenton/FAA-2021-0156-0001","comments_close_on":"2021-06-21","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by June 21, 2021.","disposition_notes":null,"docket_ids":["Docket No. FAA-2021-0156","Project Identifier AD-2020-01594-T"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Document","document_id":"FAA-2021-0156-0003"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2021-05-07","updated_at":"2024-11-06T21:42:56.576-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2021-0156-0001","allow_late_comments":true,"id":"FAA-2021-0156-0001","comment_end_date":"2021-06-22","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2021-0156","title":"Gulfstream GVII-G500GVII-G500 left and right hand wing inboard and outboard flap actuator yoke fittings"}],"document_number":"2021-09243","effective_on":null,"end_page":24549,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2021/05/07/2021-09243.xml","html_url":"https://www.federalregister.gov/documents/2021/05/07/2021-09243/airworthiness-directives-gulfstream-aerospace-corporation-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2021-09243?publication_date=2021-05-07","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2021-05-07/2021-09243/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":625,"last_updated":"2026-08-25 04:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2021-05-07/pdf/2021-09243.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2021-09243.pdf?1620305118","publication_date":"2021-05-07","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2021/05/07/2021-09243.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 Document","document_id":"FAA-2021-0156-0003"}],"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-2021-0156","supporting_documents_count":1,"docket_id":"FAA-2021-0156","document_id":"FAA-2021-0156-0001","regulation_id_number":"2120-AA64","title":"Gulfstream GVII-G500GVII-G500 left and right hand wing inboard and outboard flap actuator yoke fittings","checked_regulationsdotgov_at":"2024-11-07T23:00:19Z"},"regulations_dot_gov_url":"https://www.regulations.gov/commenton/FAA-2021-0156-0001","significant":false,"signing_date":null,"start_page":24546,"subtype":null,"title":"Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes","toc_doc":"Gulfstream Aerospace Corporation Airplanes","toc_subject":"Airworthiness Directives:\n","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":86}
