{"abstract":"The FAA is adopting a new airworthiness directive (AD) to supersede AD 2001-17-13, which applies to aircraft equipped with a Kelly Aerospace Power Systems (Kelly Aerospace) part number (P/N) 14D11, A14D11, B14D11, C14D11, 23D04, A23D04, B23D04, C23D04, or P23D04 fuel regulator shutoff valve used with Kelly Aerospace B1500, B2030, B2500, B3040, B3500, B4050, or B4500 B-Series combustion heaters. AD 2001-17-13 requires you to visually inspect or pressure test the fuel regulator shutoff valves for leaks and replace the fuel regulator shutoff valve if leaks are found. This AD is the result of continued reports of fuel regulator shutoff valve problems and the manufacturer revising the service information to modify the pressure test procedures and to specify installing improved design replacement parts. This AD retains the actions required in AD 2001-17-13, makes the inspection repetitive, and requires installing improved design replacement parts. We are issuing this AD to prevent failure of the fuel regulator shutoff valve, which could result in fuel leakage in aircraft with these combustion heaters. This failure could result in an aircraft fire.","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/2004/12/16/04-27283.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"69 FR 75228","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD becomes effective on January 5, 2005.","disposition_notes":null,"docket_ids":["Docket No. FAA-2004-19693","Directorate Identifier 2004-CE-40-AD","Amendment 39-13904","AD 2004-25-16"],"dockets":[],"document_number":"04-27283","effective_on":"2005-01-05","end_page":75231,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2004/12/16/04-27283.xml","html_url":"https://www.federalregister.gov/documents/2004/12/16/04-27283/airworthiness-directives-kelly-aerospace-power-systems-part-number-pn-14d11-a14d11-b14d11-c14d11","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/04-27283?publication_date=2004-12-16","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2004-12-16/04-27283/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":320,"last_updated":"2026-08-23 18:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2004-12-16/pdf/04-27283.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2004-12-16","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2004/12/16/04-27283.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":"2011-11-12T14:14:31Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":75228,"subtype":null,"title":"Airworthiness Directives; Kelly Aerospace Power Systems Part Number (P/N) 14D11, A14D11, B14D11, C14D11, 23D04, A23D04, B23D04, C23D04, or P23D04 Fuel Regulator Shutoff Valves (Formerly Owned by ElectroSystems, JanAero Devices, Janitrol, C&D, FL Aerospace, and Midland-Ross Corporation)","toc_doc":"Kelly Aerospace Power Systems","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":69}
