{"abstract":"The Transportation Security Administration (TSA) is amending its interpretive rule that provides guidance to the public on the types of items that TSA considers to be weapons, explosives, and incendiaries, which are prohibited in airport sterile areas, in the cabins of aircraft, or in passengers' checked baggage. This document adds a limited type of unpressurized gas cylinders for air guns used in competitive shooting to those items that may be placed in checked baggage but continue to be prohibited in sterile areas and aircraft cabins. This document also provides clarification on prohibited sharp objects and certain self-defense items.","action":"Interpretive rule.","agencies":[{"raw_name":"DEPARTMENT OF HOMELAND SECURITY","name":"Homeland Security Department","id":227,"url":"https://www.federalregister.gov/agencies/homeland-security-department","json_url":"https://www.federalregister.gov/api/v1/agencies/227","parent_id":null,"slug":"homeland-security-department"},{"raw_name":"Transportation Security Administration","name":"Transportation Security Administration","id":494,"url":"https://www.federalregister.gov/agencies/transportation-security-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/494","parent_id":227,"slug":"transportation-security-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2023/10/26/2023-23653.html","cfr_references":[{"chapter":null,"citation_url":null,"part":1540,"title":49}],"citation":"88 FR 73537","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective October 26, 2023.","disposition_notes":null,"docket_ids":[],"dockets":[{"supporting_documents":[],"agency_name":"TSA","documents":[{"comment_count":0,"comment_start_date":"2023-10-26","updated_at":"2023-10-26T10:57:45.112-04:00","comment_url":"https://www.regulations.gov/commenton/TSA-2013-0001-0259","allow_late_comments":null,"id":"TSA-2013-0001-0259","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":0,"id":"TSA-2013-0001","title":"Federal Registers for Applications, Notices, and Orders - Miscellaneous"}],"document_number":"2023-23653","effective_on":"2023-10-26","end_page":73542,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2023/10/26/2023-23653.xml","html_url":"https://www.federalregister.gov/documents/2023/10/26/2023-23653/prohibited-items","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2023-23653?publication_date=2023-10-26","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2023-10-26/2023-23653/mods.xml","not_received_for_publication":null,"page_length":6,"page_views":{"count":2736,"last_updated":"2026-04-03 16:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2023-10-26/pdf/2023-23653.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2023-23653.pdf?1698237966","publication_date":"2023-10-26","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2023/10/26/2023-23653.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[],"comments_count":0,"agency_id":"TSA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=TSA-2013-0001","supporting_documents_count":0,"docket_id":"TSA-2013-0001","document_id":"TSA-2013-0001-0259","regulation_id_number":null,"title":"Federal Registers for Applications, Notices, and Orders - Miscellaneous","checked_regulationsdotgov_at":"2023-10-27T14:00:14Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":73537,"subtype":null,"title":"Prohibited Items","toc_doc":"Prohibited Items","toc_subject":null,"topics":[],"type":"Rule","volume":88}
