{"abstract":"The FAA proposes to supersede Airworthiness Directive (AD) 2008-24-04 for Eurocopter France (now Airbus Helicopters) Model AS355E, AS355F, AS355F1, AS355F2, and AS355N helicopters. AD 2008-24-04 requires repetitively inspecting the lubricating pump and checking the magnetic chip detector plug (chip detector) and the main gearbox (MGB) oil-sight glass. Since the FAA issued AD 2008-24-04, Airbus Helicopters has developed an alteration of the MGB oil flow distribution that corrects the unsafe condition. This proposed AD would retain the requirements of AD 2008-24-04 and would allow the option of altering the MGB oil flow distribution as a terminating action for the inspections. The actions of this proposed AD are intended to address an 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/2019/12/31/2019-27978.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"84 FR 72254","comment_url":null,"comments_close_on":"2020-03-02","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by March 2, 2020.","disposition_notes":null,"docket_ids":["Docket No. FAA-2017-0404","Product Identifier 2015-SW-066-AD"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2017-0404-0005"},{"title":"Supporting AD Document","document_id":"FAA-2017-0404-0004"},{"title":"Supporting AD Documents","document_id":"FAA-2017-0404-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2019-12-31","updated_at":"2023-02-28T13:51:43.029-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2017-0404-0001","allow_late_comments":null,"id":"FAA-2017-0404-0001","comment_end_date":"2020-03-03","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":3,"id":"FAA-2017-0404","title":"Airbus Helicopters Model AS355E, AS355F, AS355F1, AS355F2, and AS355N helicopters, to require inspecting/replacing the main gearbox and the oil pump.\n\n"}],"document_number":"2019-27978","effective_on":null,"end_page":72257,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2019/12/31/2019-27978.xml","html_url":"https://www.federalregister.gov/documents/2019/12/31/2019-27978/airworthiness-directives-airbus-helicopters-previously-eurocopter-france","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2019-27978?publication_date=2019-12-31","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2019-12-31/2019-27978/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":363,"last_updated":"2026-04-04 14:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2019-12-31/pdf/2019-27978.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2019-27978.pdf?1577713518","publication_date":"2019-12-31","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2019/12/31/2019-27978.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":"Supporting AD Documents","document_id":"FAA-2017-0404-0005"},{"title":"Supporting AD Document","document_id":"FAA-2017-0404-0004"},{"title":"Supporting AD Documents","document_id":"FAA-2017-0404-0002"}],"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-2017-0404","supporting_documents_count":3,"docket_id":"FAA-2017-0404","document_id":"FAA-2017-0404-0001","regulation_id_number":"2120-AA64","title":"Airbus Helicopters Model AS355E, AS355F, AS355F1, AS355F2, and AS355N helicopters, to require inspecting/replacing the main gearbox and the oil pump.\n\n","checked_regulationsdotgov_at":"2023-02-28T18:51:42Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":72254,"subtype":null,"title":"Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France)","toc_doc":"Airbus Helicopters (Previously Eurocopter France)","toc_subject":"Airworthiness Directives:\n","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":84}
