{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model H160-B helicopters. This proposed AD was prompted by reports of missing retaining rings on the hinge pins installed on the jettisonable window systems. This proposed AD would require inspecting for missing retaining rings on all the hinge pins installed on the jettisonable window systems and, depending on findings, installing missing retaining rings. 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/2026/04/13/2026-07101.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"91 FR 18790","comment_url":"http://www.regulations.gov/commenton/FAA-2026-3482-0001","comments_close_on":"2026-05-28","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this NPRM by May 28, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2026-3482","Project Identifier MCAI-2025-01288-R"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2026-3482-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2026-04-13","updated_at":"2026-04-13T09:56:24.767-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2026-3482-0001","allow_late_comments":false,"id":"FAA-2026-3482-0001","comment_end_date":"2026-05-29","regulations_dot_gov_open_for_comment":true}],"supporting_documents_count":1,"id":"FAA-2026-3482","title":"MCAI-2025-01288-R; Airbus Helicopters Model H160B Helicopters; Jettisonable Window System Retaining Rings - Inspection"}],"document_number":"2026-07101","effective_on":null,"end_page":18792,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/04/13/2026-07101.xml","html_url":"https://www.federalregister.gov/documents/2026/04/13/2026-07101/airworthiness-directives-airbus-helicopters","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-07101?publication_date=2026-04-13","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-04-13/2026-07101/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":114,"last_updated":"2026-04-17 08:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-04-13/pdf/2026-07101.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-07101.pdf?1775825118","publication_date":"2026-04-13","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/04/13/2026-07101.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":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2026-3482-0002"}],"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-2026-3482","supporting_documents_count":1,"docket_id":"FAA-2026-3482","document_id":"FAA-2026-3482-0001","regulation_id_number":"2120-AA64","title":"MCAI-2025-01288-R; Airbus Helicopters Model H160B Helicopters; Jettisonable Window System Retaining Rings - Inspection","checked_regulationsdotgov_at":"2026-04-14T16:55:07Z"},"regulations_dot_gov_url":"http://www.regulations.gov/commenton/FAA-2026-3482-0001","significant":false,"signing_date":null,"start_page":18790,"subtype":null,"title":"Airworthiness Directives; Airbus Helicopters","toc_doc":"Airbus Helicopters","toc_subject":"Airworthiness Directives","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":91}
