{"abstract":"We propose to supersede Airworthiness Directive (AD) 2018-10- 07, which applies to Sikorsky Aircraft Corporation (Sikorsky) Model S- 76C helicopters. AD 2018-10-07 requires inspecting the engine collective position transducer (CPT). Since we issued AD 2018-10-07, we determined that an additional part-numbered engine CPT is affected by the same unsafe condition. This proposed AD would retain the requirements of AD 2018-10-07 and expand the applicability to include the additional engine CPT. We are 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/2019/05/23/2019-10772.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"84 FR 23740","comment_url":null,"comments_close_on":"2019-07-08","correction_of":null,"corrections":[],"dates":"We must receive comments on this proposed AD by July 8, 2019.","disposition_notes":null,"docket_ids":["Docket No. FAA-2019-0389","Product Identifier 2018-SW-035-AD"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2019-0389-0005"},{"title":"Disposition of Comments","document_id":"FAA-2019-0389-0004"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2019-0389-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2019-05-23","updated_at":"2023-02-28T14:17:07.678-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2019-0389-0001","allow_late_comments":null,"id":"FAA-2019-0389-0001","comment_end_date":"2019-07-09","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":3,"id":"FAA-2019-0389","title":"Sikorsky Aircraft Corporation Model S-76C helicopters, to require inspecting the engine collective position transducers.\t\n2018-SW-035-AD\n\n"}],"document_number":"2019-10772","effective_on":null,"end_page":23742,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2019/05/23/2019-10772.xml","html_url":"https://www.federalregister.gov/documents/2019/05/23/2019-10772/airworthiness-directives-sikorsky-aircraft-corporation-helicopters","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2019-10772?publication_date=2019-05-23","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2019-05-23/2019-10772/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":756,"last_updated":"2026-04-04 20:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2019-05-23/pdf/2019-10772.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2019-10772.pdf?1558529118","publication_date":"2019-05-23","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2019/05/23/2019-10772.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-2019-0389-0005"},{"title":"Disposition of Comments","document_id":"FAA-2019-0389-0004"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2019-0389-0002"}],"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-2019-0389","supporting_documents_count":3,"docket_id":"FAA-2019-0389","document_id":"FAA-2019-0389-0001","regulation_id_number":"2120-AA64","title":"Sikorsky Aircraft Corporation Model S-76C helicopters, to require inspecting the engine collective position transducers.\t\n2018-SW-035-AD\n\n","checked_regulationsdotgov_at":"2023-02-28T19:17:06Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":23740,"subtype":null,"title":"Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters","toc_doc":"Sikorsky Aircraft Corporation Helicopters","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety"],"type":"Proposed Rule","volume":84}
