{"abstract":"This document proposes adopting a new airworthiness directive (AD) for Bell Helicopter Textron (Bell) Model 206A and 206B helicopters modified by Aeronautical Accessories, Inc. Supplemental Type Certificate (STC) SH1392SO with certain part-numbered high crosstubes. The AD would require inspecting at specified time intervals and replacing any cracked crosstubes. This proposal is prompted by the discovery of a cracked high forward crosstube. The actions specified by the proposed AD are intended to detect a crack in the crosstube which could lead to failure of the crosstube, collapse of the landing gear, and subsequent loss of control of the helicopter.","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/2005/05/17/05-9762.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"70 FR 28220","comment_url":null,"comments_close_on":"2005-07-18","correction_of":null,"corrections":[],"dates":"Comments must be received on or before July 18, 2005.","disposition_notes":null,"docket_ids":["Docket No. FAA-2005-21230","Directorate Identifier 2004-SW-51-AD"],"dockets":[],"document_number":"05-9762","effective_on":null,"end_page":28221,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2005/05/17/05-9762.xml","html_url":"https://www.federalregister.gov/documents/2005/05/17/05-9762/airworthiness-directives-bell-helicopter-textron-model-206a-and-206b-helicopters","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/05-9762?publication_date=2005-05-17","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2005-05-17/05-9762/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":182,"last_updated":"2026-04-04 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2005-05-17/pdf/05-9762.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2005-05-17","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2005/05/17/05-9762.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":{"checked_regulationsdotgov_at":"2011-11-12T16:02:03Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":28220,"subtype":null,"title":"Airworthiness Directives; Bell Helicopter Textron Model 206A and 206B Helicopters","toc_doc":"Bell","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Safety"],"type":"Proposed Rule","volume":70}
