{"abstract":"We are adopting a new airworthiness directive (AD) for the products listed above. 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 smoke or fire, which could be fanned by oxygen leakage from the third crew member oxygen mask box. This AD requires actions that are intended to address the unsafe condition described in the MCAI.","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/2007/01/25/07-258.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"72 FR 3345","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD becomes effective February 9, 2007.","disposition_notes":null,"docket_ids":["Docket No. FAA-2007-26920","Directorate Identifier"],"dockets":[],"document_number":"07-258","effective_on":"2007-02-09","end_page":3347,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2007/01/25/07-258.xml","html_url":"https://www.federalregister.gov/documents/2007/01/25/07-258/airworthiness-directives-dassault-model-mystere-falcon-900-and-falcon-900ex-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/07-258?publication_date=2007-01-25","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2007-01-25/07-258/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":16,"last_updated":"2026-04-04 12:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2007-01-25/pdf/07-258.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2007-01-25","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2007/01/25/07-258.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":{"checked_regulationsdotgov_at":"2011-11-12T20:37:42Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":3345,"subtype":null,"title":"Airworthiness Directives; Dassault Model Mystere-Falcon 900 and Falcon 900EX Airplanes","toc_doc":"Dassault","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":72}
