{"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 reports of interference between the wing spar lower boom and the wheel fairing attaching screw. We are issuing this AD to require actions to correct 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/2007/01/22/E7-706.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"72 FR 2606","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD becomes effective February 26, 2007.","disposition_notes":null,"docket_ids":["Docket No. FAA-2006-26236 Directorate Identifier 2006-CE-66-AD","Amendment 39-14891","AD 2007-02-04"],"dockets":[],"document_number":"E7-706","effective_on":"2007-02-26","end_page":2608,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2007/01/22/E7-706.xml","html_url":"https://www.federalregister.gov/documents/2007/01/22/E7-706/airworthiness-directives-socata-groupe-aerospatiale-tb-20-and-tb-21-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E7-706?publication_date=2007-01-22","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2007-01-22/E7-706/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":664,"last_updated":"2026-04-04 12:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2007-01-22/pdf/E7-706.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2007-01-22","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2007/01/22/E7-706.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":"2011-11-12T20:34:45Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":2606,"subtype":null,"title":"Airworthiness Directives; SOCATA-Groupe Aerospatiale TB 20 and TB 21 Airplanes","toc_doc":"SOCATA Groupe Aerospatiale","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":72}
