{"abstract":"We propose to adopt a new airworthiness directive (AD) for certain Model 737-700 (IGW) series airplanes. This proposed AD would require deactivation or modification of PATS Aircraft, LLC, auxiliary fuel tanks. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.","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/2010/02/12/2010-2994.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"75 FR 6865","comment_url":null,"comments_close_on":"2010-03-29","correction_of":null,"corrections":[],"dates":"We must receive comments on this proposed AD by March 29, 2010.","disposition_notes":null,"docket_ids":["Docket No. FAA-2010-0037","Directorate Identifier 2009-NM-240-AD"],"dockets":[],"document_number":"2010-2994","effective_on":null,"end_page":6868,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2010/02/12/2010-2994.xml","html_url":"https://www.federalregister.gov/documents/2010/02/12/2010-2994/airworthiness-directives-the-boeing-company-model-737-700-igw-series-airplanes-equipped-with","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2010-2994?publication_date=2010-02-12","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2010-02-12/2010-2994/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":339,"last_updated":"2026-08-24 00:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2010-02-12/pdf/2010-2994.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2010-02-12","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2010/02/12/2010-2994.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":"2010-02-12T16:02:25Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":6865,"subtype":null,"title":"Airworthiness Directives; The Boeing Company Model 737-700 (IGW) Series Airplanes Equipped With Auxiliary Fuel Tanks Installed in Accordance With Configuration 3 of Supplemental Type Certificate ST00936NY","toc_doc":"Boeing Company Model 737700 (IGW) Series Airplanes Equipped with Auxiliary Fuel Tanks Installed, etc.","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":75}
