{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 airplanes. This proposed AD was prompted by a report that an incorrect low-pressure distribution supply duct may be installed in the forward cargo compartment. This proposed AD would require an inspection of the low-pressure distribution supply duct to determine the part number, and replacement if necessary, as specified in a Transport Canada Civil Aviation (TCCA) AD, which is proposed for incorporation by reference. 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/2021/04/16/2021-07564.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"86 FR 20091","comment_url":"https://www.regulations.gov/commenton/FAA-2021-0298-0001","comments_close_on":"2021-06-01","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by June 1, 2021.","disposition_notes":null,"docket_ids":["Docket No. FAA-2021-0298","Project Identifier MCAI-2020-01549-T"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Document","document_id":"FAA-2021-0298-0002"}],"agency_name":"FAA","documents":[{"comment_count":3,"comment_start_date":"2021-04-16","updated_at":"2024-11-06T20:33:28.567-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2021-0298-0001","allow_late_comments":true,"id":"FAA-2021-0298-0001","comment_end_date":"2021-06-02","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2021-0298","title":"2020-NM-XXX-AD"}],"document_number":"2021-07564","effective_on":null,"end_page":20093,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2021/04/16/2021-07564.xml","html_url":"https://www.federalregister.gov/documents/2021/04/16/2021-07564/airworthiness-directives-airbus-canada-limited-partnership-type-certificate-previously-held-by-c","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2021-07564?publication_date=2021-04-16","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2021-04-16/2021-07564/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":112,"last_updated":"2026-04-04 12:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2021-04-16/pdf/2021-07564.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2021-07564.pdf?1618490718","publication_date":"2021-04-16","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2021/04/16/2021-07564.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":"Supporting AD Document","document_id":"FAA-2021-0298-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":3,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2021-0298","supporting_documents_count":1,"docket_id":"FAA-2021-0298","document_id":"FAA-2021-0298-0001","regulation_id_number":"2120-AA64","title":"2020-NM-XXX-AD","checked_regulationsdotgov_at":"2024-11-07T01:01:24Z"},"regulations_dot_gov_url":"https://www.regulations.gov/commenton/FAA-2021-0298-0001","significant":false,"signing_date":null,"start_page":20091,"subtype":null,"title":"Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.)
