{"abstract":"We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2A12 (CL-601 Variant) and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. This AD was prompted by a determination that the bushing holes on the engine mount rib might not conform to the engineering drawings and that certain inspections of the engine mount rib must be included in the airworthiness limitations section (ALS) of the Instructions for Continued Airworthiness (ICA). This AD requires revising the maintenance or inspection program to incorporate certain airworthiness limitation items (ALIs). We are issuing this AD to address 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/2017/11/20/2017-24737.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"82 FR 55040","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective December 26, 2017.","disposition_notes":null,"docket_ids":["Docket No. FAA-2017-0338","Product Identifier 2016-NM-153-AD","Amendment 39-19103","AD 2017-23-09"],"dockets":[{"supporting_documents":[{"title":"Signed MOC AD 2017-23-09","document_id":"FAA-2017-0338-0006"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2017-0338-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2017-11-20","updated_at":"2023-03-01T15:51:17.258-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2017-0338-0005","allow_late_comments":null,"id":"FAA-2017-0338-0005","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2017-0338","title":"2016-NM-153-AD\nBombardier, Inc., Model CL‑600‑2A12 (CL‑601 Variant) and CL-600‑2B16 (CL‑601‑3A, CL‑601‑3R, and CL‑604 Variants) airplanes"}],"document_number":"2017-24737","effective_on":"2017-12-26","end_page":55042,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2017/11/20/2017-24737.xml","html_url":"https://www.federalregister.gov/documents/2017/11/20/2017-24737/airworthiness-directives-bombardier-inc-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2017-24737?publication_date=2017-11-20","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2017-11-20/2017-24737/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":215,"last_updated":"2026-04-04 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2017-11-20/pdf/2017-24737.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2017-24737.pdf?1510926322","publication_date":"2017-11-20","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2017/11/20/2017-24737.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":"Signed MOC AD 2017-23-09","document_id":"FAA-2017-0338-0006"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2017-0338-0002"}],"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-2017-0338","supporting_documents_count":2,"docket_id":"FAA-2017-0338","document_id":"FAA-2017-0338-0005","regulation_id_number":"2120-AA64","title":"2016-NM-153-AD\nBombardier, Inc., Model CL‑600‑2A12 (CL‑601 Variant) and CL-600‑2B16 (CL‑601‑3A, CL‑601‑3R, and CL‑604 Variants) airplanes","checked_regulationsdotgov_at":"2023-03-01T20:51:16Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":55040,"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}
