{"abstract":"We are adopting a new airworthiness directive (AD) for all 328 Support Services GmbH Model 328-100 and -300 airplanes. This AD was prompted by reports indicating corrosion on the horizontal stabilizer bearing supports at the contact surface to the horizontal stabilizer rear spar. This AD requires inspections for corrosion and any other damage (i.e., cracking and chafing) of the horizontal stabilizer rear bearing supports, replacement of the affected horizontal stabilizer rear bearing supports if necessary, and modification of the horizontal stabilizer rear spar. We are 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/2018/09/26/2018-20357.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"83 FR 48524","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective October 31, 2018.","disposition_notes":null,"docket_ids":["Docket No. FAA-2018-0503","Product Identifier 2018-NM-048-AD","Amendment 39-19413","AD 2018-19-13"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2018-0503-0005"},{"title":"Supporting AD Documents","document_id":"FAA-2018-0503-0003"},{"title":"U.S. DOT/FAA - Product ID 2018-NM-048-AD","document_id":"FAA-2018-0503-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2018-09-26","updated_at":"2023-03-01T14:38:14.029-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2018-0503-0004","allow_late_comments":null,"id":"FAA-2018-0503-0004","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":3,"id":"FAA-2018-0503","title":"2018-NM-048-AD\n328 Support Services GmbH Model 328‑100 and -300 airplanes"}],"document_number":"2018-20357","effective_on":"2018-10-31","end_page":48527,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2018/09/26/2018-20357.xml","html_url":"https://www.federalregister.gov/documents/2018/09/26/2018-20357/airworthiness-directives-328-support-services-gmbh-type-certificate-previously-held-by-avcraft","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2018-20357?publication_date=2018-09-26","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2018-09-26/2018-20357/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":104,"last_updated":"2026-09-20 10:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2018-09-26/pdf/2018-20357.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2018-20357.pdf?1537879518","publication_date":"2018-09-26","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2018/09/26/2018-20357.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-2018-0503-0005"},{"title":"Supporting AD Documents","document_id":"FAA-2018-0503-0003"},{"title":"U.S. DOT/FAA - Product ID 2018-NM-048-AD","document_id":"FAA-2018-0503-0002"}],"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-2018-0503","supporting_documents_count":3,"docket_id":"FAA-2018-0503","document_id":"FAA-2018-0503-0004","regulation_id_number":"2120-AA64","title":"2018-NM-048-AD\n328 Support Services GmbH Model 328‑100 and -300 airplanes","checked_regulationsdotgov_at":"2023-03-01T19:38:13Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":48524,"subtype":null,"title":"Airworthiness Directives; 328 Support Services GmbH (Type Certificate Previously Held by AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) Airplanes","toc_doc":"328 Support Services GmbH (Type Certificate Previously Held by AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) Airplanes","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":83}
