{"abstract":"We are revising an earlier proposed airworthiness directive (AD) for Eurocopter Deutschland GmbH (Eurocopter) Model BO-105A, BO- 105C, BO-105LS A-1, BO-105LS A-3, and BO-105S helicopters, which proposed inspecting for debonding of the erosion protective shell (abrasion strip) on the leading edge of each main rotor blade. This SNPRM proposes to revise those inspection requirements by identifying specific dates of replacement of the applicable parts and identifying a specific inspection method for debonding of an abrasion strip.","action":"Supplemental notice of proposed rulemaking (SNPRM); reopening of comment period.","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/2012/12/19/2012-30588.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"77 FR 75073","comment_url":null,"comments_close_on":"2013-02-04","correction_of":null,"corrections":[],"dates":"We must receive comments on this proposed AD by February 4, 2013.","disposition_notes":null,"docket_ids":["Docket No. FAA-2011-1285","Directorate Identifier 2010-SW-073-AD"],"dockets":[],"document_number":"2012-30588","effective_on":null,"end_page":75075,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2012/12/19/2012-30588.xml","html_url":"https://www.federalregister.gov/documents/2012/12/19/2012-30588/airworthiness-directives-eurocopter-deutschland-gmbh-helicopters","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2012-30588?publication_date=2012-12-19","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2012-12-19/2012-30588/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":66,"last_updated":"2026-04-04 12:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2012-12-19/pdf/2012-30588.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2012-30588.pdf?1355839722","publication_date":"2012-12-19","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2012/12/19/2012-30588.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":{"supporting_documents":[{"title":"U.S. DOT/FAA - See Attachment","document_id":"FAA-2011-1285-0008"},{"title":"U.S. DOT/FAA - See Attachments","document_id":"FAA-2011-1285-0007"},{"title":"U.S. DOT/FAA - See Attachment","document_id":"FAA-2011-1285-0003"},{"title":"U.S. DOT/FAA - See Attachments","document_id":"FAA-2011-1285-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2011-1285","supporting_documents_count":4,"docket_id":"FAA-2011-1285","regulation_id_number":"2120-AA64","title":"2009-SW-51-AD Eurocopter France Model SA341G Helicopters","checked_regulationsdotgov_at":"2013-02-16T05:00:33Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":75073,"subtype":null,"title":"Airworthiness Directives; Eurocopter Deutschland GmbH Helicopters","toc_doc":"Eurocopter Deutschland GmbH Helicopters","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":77}
