{"abstract":"This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 777-200 and -300 series airplanes. This action requires replacement of the switch guard on the switch used to control the passenger and/or therapeutic oxygen system with a new, improved switch guard. This action is necessary to prevent displacement of the passenger/therapeutic oxygen switch, which could result in the unavailability of supplemental/therapeutic oxygen and possible incapacitation of passengers during flight. This action is intended to address the identified unsafe condition.","action":"Final rule; request for comments.","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/2002/04/02/02-7414.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"67 FR 15470","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective April 17, 2002.","disposition_notes":null,"docket_ids":["Docket No. 2002-NM-22-AD","Amendment 39-12693","AD 2002-06-15"],"dockets":[],"document_number":"02-7414","effective_on":"2002-04-17","end_page":15472,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2002/04/02/02-7414.xml","html_url":"https://www.federalregister.gov/documents/2002/04/02/02-7414/airworthiness-directives-boeing-model-777-200-and--300-series-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/02-7414?publication_date=2002-04-02","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2002-04-02/02-7414/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":34,"last_updated":"2026-04-04 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2002-04-02/pdf/02-7414.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2002-04-02","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2002/04/02/02-7414.txt","regulation_id_number_info":{"2120-AA64":{"issue":"202504","html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202504&RIN=2120-AA64&operation=OPERATION_EXPORT_XML","priority_category":"Routine and Frequent"}},"regulation_id_numbers":["2120-AA64"],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":15470,"subtype":null,"title":"Airworthiness Directives; Boeing Model 777-200 and -300 Series Airplanes","toc_doc":"Boeing","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":67}
