{"abstract":"We are adopting a new airworthiness directive (AD) for certain Diamond Aircraft Industries GmbH Models DA 42 NG and DA 42 M-NG airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as the failure of the alternator indication system to indicate warning when one alternator is inoperative. We are issuing this AD to require actions 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/2014/03/03/2014-03604.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"79 FR 11695","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective April 7, 2014.","disposition_notes":null,"docket_ids":["Docket No. FAA-2013-0937","Directorate Identifier 2013-CE-029-AD","Amendment 39-17762","AD 2014-04-04"],"dockets":[],"document_number":"2014-03604","effective_on":"2014-04-07","end_page":11697,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2014/03/03/2014-03604.xml","html_url":"https://www.federalregister.gov/documents/2014/03/03/2014-03604/airworthiness-directives-diamond-aircraft-industries-gmbh-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2014-03604?publication_date=2014-03-03","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2014-03-03/2014-03604/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":134,"last_updated":"2026-04-24 06:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2014-03-03/pdf/2014-03604.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2014-03604.pdf?1393595309","publication_date":"2014-03-03","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2014/03/03/2014-03604.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":{"checked_regulationsdotgov_at":"2014-03-23T06:00:10Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":11695,"subtype":null,"title":"Airworthiness Directives; Diamond Aircraft Industries GmbH Airplanes","toc_doc":"Diamond Aircraft Industries GmbH Airplanes","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":79}
