{"abstract":"The FAA is adopting a new airworthiness directive (AD) for all DG Flugzeugbau GmbH Models DG-808C and DG-1000T gliders. This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as damaged fuel hoses due to environmental and fatigue deterioration. This AD requires inspecting the polyurethane (PU) fuel hoses, replacing the PU fuel hoses if there is damage, and establishing a life limit for the PU fuel hoses. 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/2021/09/30/2021-21095.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"86 FR 54037","comment_url":"https://www.regulations.gov/commenton/FAA-2021-0212-0004","comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective November 4, 2021.","disposition_notes":null,"docket_ids":["Docket No. FAA-2021-0212","Project Identifier 2018-CE-032-AD","Amendment 39-21715","AD 2021-18-14"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2021-0212-0005"},{"title":"Supporting AD Document","document_id":"FAA-2021-0212-0003"},{"title":"Supporting AD Document","document_id":"FAA-2021-0212-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2021-09-30","updated_at":"2024-11-06T20:42:02.696-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2021-0212-0004","allow_late_comments":true,"id":"FAA-2021-0212-0004","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":3,"id":"FAA-2021-0212","title":"DG Flugzeugbau DG-808C/DG-1000T fuel hoses, 2018-CE-032-AD"}],"document_number":"2021-21095","effective_on":"2021-11-04","end_page":54039,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2021/09/30/2021-21095.xml","html_url":"https://www.federalregister.gov/documents/2021/09/30/2021-21095/airworthiness-directives-dg-flugzeugbau-gmbh-gliders","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2021-21095?publication_date=2021-09-30","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2021-09-30/2021-21095/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":175,"last_updated":"2026-07-25 20:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2021-09-30/pdf/2021-21095.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2021-21095.pdf?1632919523","publication_date":"2021-09-30","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2021/09/30/2021-21095.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-2021-0212-0005"},{"title":"Supporting AD Document","document_id":"FAA-2021-0212-0003"},{"title":"Supporting AD Document","document_id":"FAA-2021-0212-0002"}],"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-2021-0212","supporting_documents_count":3,"docket_id":"FAA-2021-0212","document_id":"FAA-2021-0212-0004","regulation_id_number":"2120-AA64","title":"DG Flugzeugbau DG-808C/DG-1000T fuel hoses, 2018-CE-032-AD","checked_regulationsdotgov_at":"2024-11-07T01:53:41Z"},"regulations_dot_gov_url":"https://www.regulations.gov/commenton/FAA-2021-0212-0004","significant":false,"signing_date":null,"start_page":54037,"subtype":null,"title":"Airworthiness Directives; DG Flugzeugbau GmbH Gliders","toc_doc":"DG Flugzeugbau GmbH Gliders","toc_subject":"Airworthiness Directives:\n","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":86}
