{"abstract":"This amendment supersedes Airworthiness Directive (AD) 2001- 08-01, which applies to certain JanAero Devices (JanAero) 14D11 and 23D04 series fuel regulator shutoff valves used with certain JanAero combustion heaters that are installed on aircraft. AD 2001-08-01 currently requires you to visually inspect and pressure test these fuel regulator shutoff valves for leaks, and, if leaks are found, replace the fuel regulator shutoff valve. Numerous reports of fuel regulator shutoff valves leaking fuel caused the Federal Aviation Administration (FAA) to issue AD 2001-08-01. This amendment retains the actions of AD 2001-08- 01, except only the visual inspection or the pressure test will be required instead of both. This amendment also specifically calls out the fuel regulator shutoff valves by part number instead of series, includes provisions for disabling the heater as an alternative method of compliance, and makes other minor clarifying revisions and additions to the AD. The actions specified by this AD are intended to eliminate or severely reduce the potential for fuel leakage in aircraft with these combustion heaters, which could result in an aircraft fire with consequent damage or destruction.","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/2001/08/22/01-21010.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"66 FR 44027","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD becomes effective on September 11, 2001.","disposition_notes":null,"docket_ids":["Docket No. 2001-CE-26-AD","Amendment 39-12404","AD 2001-17-13"],"dockets":[],"document_number":"01-21010","effective_on":"2001-09-11","end_page":44030,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2001/08/22/01-21010.xml","html_url":"https://www.federalregister.gov/documents/2001/08/22/01-21010/airworthiness-directives-janaero-devices-part-number-pn-14d11-a14d11-b14d11-c14d11-23d04-a23d04","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/01-21010?publication_date=2001-08-22","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2001-08-22/01-21010/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":229,"last_updated":"2026-08-24 22:15:11 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2001-08-22/pdf/01-21010.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2001-08-22","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2001/08/22/01-21010.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":{"checked_regulationsdotgov_at":"2011-11-12T05:15:51Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":44027,"subtype":null,"title":"Airworthiness Directives; JanAero Devices Part Number (P/N) 14D11, A14D11, B14D11, C14D11, 23D04, A23D04, B23D04, and C23D04 Fuel Regulator Shutoff Valves","toc_doc":"JanAero Devices","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":66}
