{"abstract":"The FAA proposes to supersede Airworthiness Directive (AD) 2019-08-13 for Textron Aviation, Inc. (type certificate previously held by Cessna Aircraft Company) Models 525, 525A, and 525B airplanes with Tamarack active load alleviation system (ATLAS) winglets installed in accordance with Supplemental Type Certificate (STC) SA03842NY. AD 2019- 08-13 resulted 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 malfunction of the ATLAS. This AD results from the identification of corrective actions that, if implemented, allow operators to reactivate the ATLAS and restore operations to normal procedures. The FAA is proposing this AD 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/2020/06/02/2020-11351.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"85 FR 33583","comment_url":null,"comments_close_on":"2020-07-17","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by July 17, 2020.","disposition_notes":null,"docket_ids":["Docket No. FAA-2020-0493","Product Identifier 2019-CE-046-AD"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2020-0493-0006"},{"title":"Supporting AD Document","document_id":"FAA-2020-0493-0002"}],"agency_name":"FAA","documents":[{"comment_count":2,"comment_start_date":"2020-06-02","updated_at":"2023-03-01T03:52:44.994-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2020-0493-0001","allow_late_comments":null,"id":"FAA-2020-0493-0001","comment_end_date":"2020-07-18","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2020-0493","title":"Textron 525 with Tamarack ATLAS winglets; AFM additions and STC modification, 2019-CE-046-AD"}],"document_number":"2020-11351","effective_on":null,"end_page":33587,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2020/06/02/2020-11351.xml","html_url":"https://www.federalregister.gov/documents/2020/06/02/2020-11351/airworthiness-directives-textron-aviation-inc-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2020-11351?publication_date=2020-06-02","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2020-06-02/2020-11351/mods.xml","not_received_for_publication":null,"page_length":5,"page_views":{"count":467,"last_updated":"2026-08-26 10:15:07 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2020-06-02/pdf/2020-11351.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2020-11351.pdf?1591015519","publication_date":"2020-06-02","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2020/06/02/2020-11351.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-2020-0493-0006"},{"title":"Supporting AD Document","document_id":"FAA-2020-0493-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":2,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2020-0493","supporting_documents_count":2,"docket_id":"FAA-2020-0493","document_id":"FAA-2020-0493-0001","regulation_id_number":"2120-AA64","title":"Textron 525 with Tamarack ATLAS winglets; AFM additions and STC modification, 2019-CE-046-AD","checked_regulationsdotgov_at":"2023-03-01T08:52:44Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":33583,"subtype":null,"title":"Airworthiness Directives; Textron Aviation, Inc.
