{"abstract":"The FAA is withdrawing a previously published NPRM that proposed to establish one set of duty period limitations, flight time limitations, and rest requirements for flight crewmembers engaged in air transportation. The NPRM also proposed to establish consistent and clear duty period limitations, flight time limitations, and rest requirements for domestic, flag, supplemental, commuter and on-demand operations. We are withdrawing the NPRM because it is outdated and because of the many significant issues commenters raised. The FAA intends to issue a new NPRM to address flight, duty, and rest.","action":"Notice of proposed rulemaking (NPRM); withdrawal.","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/2009/11/23/E9-28054.html","cfr_references":[{"chapter":null,"citation_url":null,"part":121,"title":14},{"chapter":null,"citation_url":null,"part":135,"title":14}],"citation":"74 FR 61067","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The proposed rule published on December 20, 1995 (60 FR 65951), is withdrawn as of November 23, 2009.","disposition_notes":null,"docket_ids":["Docket No. 28081"],"dockets":[],"document_number":"E9-28054","effective_on":null,"end_page":61068,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2009/11/23/E9-28054.xml","html_url":"https://www.federalregister.gov/documents/2009/11/23/E9-28054/flight-crewmember-duty-period-limitations-flight-time-limitations-and-rest-requirements-withdrawal","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E9-28054?publication_date=2009-11-23","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2009-11-23/E9-28054/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":234,"last_updated":"2026-04-04 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2009-11-23/pdf/E9-28054.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2009-11-23","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2009/11/23/E9-28054.txt","regulation_id_number_info":{"2120-AF63":{"issue":"200210","html_url":"https://www.federalregister.gov/regulations/2120-AF63/flight-crewmember-duty-period-limitations-flight-time-limitations-and-rest-requirements","title":"Flight Crewmember Duty Period Limitations, Flight Time Limitations, and Rest Requirements","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200210&RIN=2120-AF63&operation=OPERATION_EXPORT_XML","priority_category":"Other Significant"},"2120-AI93":{"issue":"201004","html_url":"https://www.federalregister.gov/regulations/2120-AI93/flight-crewmember-duty-limitations-and-rest-requirements","title":"Flight Crewmember Duty Limitations and Rest Requirements","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201004&RIN=2120-AI93&operation=OPERATION_EXPORT_XML","priority_category":"Economically Significant"}},"regulation_id_numbers":["2120-AF63","2120-AI93"],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":true,"signing_date":null,"start_page":61067,"subtype":null,"title":"Flight Crewmember Duty Period Limitations, Flight Time Limitations and Rest Requirements; Withdrawal","toc_doc":"Flight Time Limitations and Rest Requirements; Withdrawal","toc_subject":"Flight Crewmember Duty Period Limitations:","topics":[],"type":"Proposed Rule","volume":74}
