{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This proposed AD was prompted by an in-flight uncommanded, unarrested flaps movement accompanied by a FLAPS FAIL caution message. This proposed AD would require revising the existing aircraft flight manual (AFM) to provide the flightcrew with procedures to follow in the event of an uncommanded, unarrested flap movement. 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/2026/05/26/2026-10382.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"91 FR 30516","comment_url":"http://www.regulations.gov/commenton/FAA-2026-4642-0001","comments_close_on":"2026-07-10","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by July 10, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2026-4642","Project Identifier MCAI-2024-00705-T"],"dockets":[{"supporting_documents":[],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2026-05-26","updated_at":"2026-05-26T08:56:22.527-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2026-4642-0001","allow_late_comments":false,"id":"FAA-2026-4642-0001","comment_end_date":"2026-07-11","regulations_dot_gov_open_for_comment":true}],"supporting_documents_count":0,"id":"FAA-2026-4642","title":"2026-NM-XXXX"}],"document_number":"2026-10382","effective_on":null,"end_page":30519,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/05/26/2026-10382.xml","html_url":"https://www.federalregister.gov/documents/2026/05/26/2026-10382/airworthiness-directives-bombardier-inc-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-10382?publication_date=2026-05-26","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-05-26/2026-10382/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":137,"last_updated":"2026-05-28 12:15:07 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-05-26/pdf/2026-10382.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-10382.pdf?1779453913","publication_date":"2026-05-26","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/05/26/2026-10382.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":[],"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-2026-4642","supporting_documents_count":0,"docket_id":"FAA-2026-4642","document_id":"FAA-2026-4642-0001","regulation_id_number":"2120-AA64","title":"2026-NM-XXXX","checked_regulationsdotgov_at":"2026-05-27T15:55:05Z"},"regulations_dot_gov_url":"http://www.regulations.gov/commenton/FAA-2026-4642-0001","significant":false,"signing_date":null,"start_page":30516,"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":"Proposed Rule","volume":91}
