{"abstract":"We propose to adopt a new airworthiness directive (AD) for Diamond Aircraft Industries GmbH Model H-36, HK 36 R, HK 36 TS, and HK 36 TTS airplanes. This proposed AD results from 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 describes the unsafe condition as installation of an unsuitable self-locking nut on the bell crank of the elevator push rod that can cause failure of the elevator, resulting in loss of control. We are issuing this proposed AD to require actions 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/2012/11/05/2012-26971.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"77 FR 66409","comment_url":null,"comments_close_on":"2012-12-20","correction_of":null,"corrections":[],"dates":"We must receive comments on this proposed AD by December 20, 2012.","disposition_notes":null,"docket_ids":["Docket No. FAA-2012-1172","Directorate Identifier 2012-CE-040-AD"],"dockets":[],"document_number":"2012-26971","effective_on":null,"end_page":66411,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2012/11/05/2012-26971.xml","html_url":"https://www.federalregister.gov/documents/2012/11/05/2012-26971/airworthiness-directives-diamond-aircraft-industries-gmbh-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2012-26971?publication_date=2012-11-05","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2012-11-05/2012-26971/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":54,"last_updated":"2026-04-04 00:15:02 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2012-11-05/pdf/2012-26971.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2012-26971.pdf?1351860795","publication_date":"2012-11-05","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2012/11/05/2012-26971.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":"U.S. DOT/FAA - See Attachment","document_id":"FAA-2012-1172-0006"},{"title":"U.S. DOT/FAA - See Attachments","document_id":"FAA-2012-1172-0004"},{"title":"U.S. DOT/FAA - See Attachments","document_id":"FAA-2012-1172-0002"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2012-1172","supporting_documents_count":3,"docket_id":"FAA-2012-1172","regulation_id_number":null,"title":"2012-CE- 040-AD","checked_regulationsdotgov_at":"2012-11-29T05:00:17Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":66409,"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":"Proposed Rule","volume":77}
