{"abstract":"The FAA is withdrawing a previously published advance notice of proposed rulemaking that sought public comment from interested persons involving glider operations in the National Airspace System. The action responded to recommendations from members of Congress and the National Transportation Safety Board and was intended to gather information to determine whether the current glider exception from transponder equipage and use provides the appropriate level of safety in the National Airspace System. The FAA is withdrawing that action because the limited safety benefit gained does not justify the high cost of equipage.","action":"Advance notice of proposed rulemaking (ANPRM); withdrawal.","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/2016/12/23/2016-30910.html","cfr_references":[{"chapter":null,"citation_url":null,"part":91,"title":14}],"citation":"81 FR 94277","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This action becomes effective December 23, 2016.","disposition_notes":null,"docket_ids":["Docket No. FAA-2015-2147","Notice No. 15-05"],"dockets":[],"document_number":"2016-30910","effective_on":"2016-12-23","end_page":94281,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2016/12/23/2016-30910.xml","html_url":"https://www.federalregister.gov/documents/2016/12/23/2016-30910/transponder-requirement-for-gliders-withdrawal","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2016-30910?publication_date=2016-12-23","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2016-12-23/2016-30910/mods.xml","not_received_for_publication":null,"page_length":5,"page_views":{"count":2727,"last_updated":"2026-04-24 06:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2016-12-23/pdf/2016-30910.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2016-30910.pdf?1482414363","publication_date":"2016-12-23","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2016/12/23/2016-30910.txt","regulation_id_number_info":{"2120-AK51":{"issue":"201610","html_url":"https://www.federalregister.gov/regulations/2120-AK51/transponder-requirement-for-gliders","title":"Transponder Requirement for Gliders","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201610&RIN=2120-AK51&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2120-AK51"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"The Honorable Mark Amodei","document_id":"FAA-2015-2147-0021"},{"title":"The Honorable Harry Reid","document_id":"FAA-2015-2147-0020"},{"title":"Executive Order 12866","document_id":"FAA-2015-2147-0019"},{"title":"National Transportation Safety Board - Safety Recommendations","document_id":"FAA-2015-2147-0018"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AK51/transponder-requirement-for-gliders","title":"Transponder Requirement for Gliders"},"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2015-2147","supporting_documents_count":4,"docket_id":"FAA-2015-2147","regulation_id_number":"2120-AK51","title":"Transponder Requirement for Gliders","checked_regulationsdotgov_at":"2017-01-12T06:00:19Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":94277,"subtype":null,"title":"Transponder Requirement for Gliders; Withdrawal","toc_doc":"Transponder Requirement for Gliders; Withdrawal","toc_subject":null,"topics":[],"type":"Proposed Rule","volume":81}
