{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for all AHD Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, EC135T3, EC635T2+, MBB-BK 117 C-2, and MBB-BK 117 D- 2 helicopters. This proposed AD was prompted by reports of cracks on the cable drum of the rescue hoist assembly. This proposed AD would require repetitively inspecting the cable drum of certain rescue hoist assemblies for cracks and depending on the results, replacing or repairing the cable drum of the rescue hoist assembly. This proposed AD would also prohibit the operation and the installation of an affected rescue hoist assembly on a helicopter, unless certain requirements are met. 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/2026/02/13/2026-02923.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"91 FR 6795","comment_url":null,"comments_close_on":"2026-03-30","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this NPRM by March 30, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2026-1326","Project Identifier MCAI-2025-00312-R"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2026-1326-0002"}],"agency_name":"FAA","documents":[{"comment_count":3,"comment_start_date":"2026-02-13","updated_at":"2026-03-31T01:56:26.444-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2026-1326-0001","allow_late_comments":false,"id":"FAA-2026-1326-0001","comment_end_date":"2026-03-31","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2026-1326","title":"MCAI-2025-00312-R; AIRBUS HELICOPTERS DEUTSCHLAND GmbH EC135, EC635 and MBB-BK117 Equipment / Furnishings – Rescue Hoist Cable Drum – Inspection"}],"document_number":"2026-02923","effective_on":null,"end_page":6798,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/02/13/2026-02923.xml","html_url":"https://www.federalregister.gov/documents/2026/02/13/2026-02923/airworthiness-directives-airbus-helicopters-deutschland-gmbh-ahd-helicopters","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-02923?publication_date=2026-02-13","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-02-13/2026-02923/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":151,"last_updated":"2026-04-04 02:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-02-13/pdf/2026-02923.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-02923.pdf?1770903916","publication_date":"2026-02-13","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/02/13/2026-02923.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-2026-1326-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":3,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2026-1326","supporting_documents_count":1,"docket_id":"FAA-2026-1326","document_id":"FAA-2026-1326-0001","regulation_id_number":"2120-AA64","title":"MCAI-2025-00312-R; AIRBUS HELICOPTERS DEUTSCHLAND GmbH EC135, EC635 and MBB-BK117 Equipment / Furnishings – Rescue Hoist Cable Drum – Inspection","checked_regulationsdotgov_at":"2026-03-31T21:55:04Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":6795,"subtype":null,"title":"Airworthiness Directives; Airbus Helicopters Deutschland GmbH (AHD) Helicopters","toc_doc":"Airbus Helicopters Deutschland GmbH (AHD) Helicopters","toc_subject":"Airworthiness Directives","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":91}
