{"abstract":"We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD requires a detailed inspection of the circuit breakers, replacement of damaged circuit breakers, and installation of a circuit breaker bushing assembly. This AD was prompted by a report of cracks found in the plastic casing of cockpit circuit breaker panels. We are issuing this AD to address the unsafe condition on these products.","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/2017/04/26/2017-08184.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"82 FR 19179","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD becomes effective May 11, 2017.","disposition_notes":null,"docket_ids":["Docket No. FAA-2017-0252","Directorate Identifier 2016-NM-187-AD","Amendment 39-18863","AD 2017-09-01"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supporting AD Documents","document_id":"FAA-2017-0252-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2017-04-26","updated_at":"2023-03-01T13:27:58.438-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2017-0252-0001","allow_late_comments":null,"id":"FAA-2017-0252-0001","comment_end_date":"2017-06-13","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2017-0252","title":"2016-NM-187-AD\nBombardier, Inc., Model CL‑600‑2E25 (Regional Jet Series 1000) airplanes"}],"document_number":"2017-08184","effective_on":"2017-05-11","end_page":19181,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2017/04/26/2017-08184.xml","html_url":"https://www.federalregister.gov/documents/2017/04/26/2017-08184/airworthiness-directives-bombardier-inc-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2017-08184?publication_date=2017-04-26","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2017-04-26/2017-08184/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":75,"last_updated":"2026-04-04 20:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2017-04-26/pdf/2017-08184.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2017-08184.pdf?1493124320","publication_date":"2017-04-26","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2017/04/26/2017-08184.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 - Supporting AD Documents","document_id":"FAA-2017-0252-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":0,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2017-0252","supporting_documents_count":1,"docket_id":"FAA-2017-0252","document_id":"FAA-2017-0252-0001","regulation_id_number":"2120-AA64","title":"2016-NM-187-AD\nBombardier, Inc., Model CL‑600‑2E25 (Regional Jet Series 1000) airplanes","checked_regulationsdotgov_at":"2023-03-01T18:27:57Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":19179,"subtype":null,"title":"Airworthiness Directives; Bombardier, Inc., Airplanes","toc_doc":"Bombardier, Inc., Airplanes","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":82}
