{"abstract":"We are adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by reports that electro-hydrostatic actuators (EHAs), installed on the inboard ailerons, elevators, and rudder, had degraded insulation resistance in the direct drive solenoid valve (DDSOV), due to incorrect sealing application. This AD requires a check of the insulation resistance of the DDSOV of each affected EHA and applicable corrective actions. We are issuing this AD to address the unsafe condition on these products.","action":"Final rule; request for comments.","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/2018/08/15/2018-17482.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"83 FR 40438","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD becomes effective August 30, 2018.","disposition_notes":null,"docket_ids":["Docket No. FAA-2018-0709","Product Identifier 2018-NM-100-AD","Amendment 39-19359","AD 2018-17-05"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2018-0709-0002"}],"agency_name":"FAA","documents":[{"comment_count":2,"comment_start_date":"2018-08-15","updated_at":"2023-03-01T14:36:57.713-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2018-0709-0001","allow_late_comments":null,"id":"FAA-2018-0709-0001","comment_end_date":"2018-10-02","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2018-0709","title":"2018-NM-100-AD\nAirbus SAS Model A350-941 and -1041 airplanes"}],"document_number":"2018-17482","effective_on":"2018-08-30","end_page":40443,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2018/08/15/2018-17482.xml","html_url":"https://www.federalregister.gov/documents/2018/08/15/2018-17482/airworthiness-directives-airbus-sas-airplanes","images":{"ER15AU18.001":{"large":"https://img.federalregister.gov/ER15AU18.001/ER15AU18.001_large.png","original_size":"https://img.federalregister.gov/ER15AU18.001/ER15AU18.001_original_size.png"}},"images_metadata":{"ER15AU18.001":{"large":{"identifier":"ER15AU18.001","content_type":"image/png","size":31267,"width":823,"sha":"23936ddad12618358f09e0eb9c73d24f","url":"https://img.federalregister.gov/ER15AU18.001/ER15AU18.001_large.png","height":423},"original_size":{"identifier":"ER15AU18.001","content_type":"image/png","size":47445,"width":3614,"sha":"86b04b600bd7c0f076e9e90ba719e1ee","url":"https://img.federalregister.gov/ER15AU18.001/ER15AU18.001_original_size.png","height":1857}}},"json_url":"https://www.federalregister.gov/api/v1/documents/2018-17482?publication_date=2018-08-15","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2018-08-15/2018-17482/mods.xml","not_received_for_publication":null,"page_length":6,"page_views":{"count":161,"last_updated":"2026-04-05 00:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2018-08-15/pdf/2018-17482.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2018-17482.pdf?1534250717","publication_date":"2018-08-15","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2018/08/15/2018-17482.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":"Supporting AD Documents","document_id":"FAA-2018-0709-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":2,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2018-0709","supporting_documents_count":1,"docket_id":"FAA-2018-0709","document_id":"FAA-2018-0709-0001","regulation_id_number":"2120-AA64","title":"2018-NM-100-AD\nAirbus SAS Model A350-941 and -1041 airplanes","checked_regulationsdotgov_at":"2023-03-01T19:36:56Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":40438,"subtype":null,"title":"Airworthiness Directives; Airbus SAS Airplanes","toc_doc":"Airbus SAS Airplanes","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":83}
