{"abstract":"We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-800 series airplanes. This proposed AD was prompted by reports of inadequate clearance between a certain fuel quantity indicating system (FQIS) tank unit and a certain reinforcement angle upon accomplishment of a certain modification. This proposed AD would require a detailed inspection to measure the clearance between the FQIS tank unit and a certain reinforcement angle, and repair if necessary. We are proposing this AD to address the unsafe condition on these products.","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/2019/05/14/2019-09866.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"84 FR 21279","comment_url":null,"comments_close_on":"2019-06-28","correction_of":null,"corrections":[],"dates":"We must receive comments on this proposed AD by June 28, 2019.","disposition_notes":null,"docket_ids":["Docket No. FAA-2019-0323","Product Identifier 2019-NM-026-AD"],"dockets":[{"supporting_documents":[{"title":"Regulatory Evaluation","document_id":"FAA-2019-0323-0003"},{"title":"Supporting AD Documents","document_id":"FAA-2019-0323-0002"}],"agency_name":"FAA","documents":[{"comment_count":3,"comment_start_date":"2019-05-14","updated_at":"2023-02-28T14:18:33.490-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2019-0323-0001","allow_late_comments":null,"id":"FAA-2019-0323-0001","comment_end_date":"2019-06-29","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2019-0323","title":"2019-NM-026-AD\nThe Boeing Company Model 737-800 series airplanes"}],"document_number":"2019-09866","effective_on":null,"end_page":21282,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2019/05/14/2019-09866.xml","html_url":"https://www.federalregister.gov/documents/2019/05/14/2019-09866/airworthiness-directives-the-boeing-company-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2019-09866?publication_date=2019-05-14","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2019-05-14/2019-09866/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":305,"last_updated":"2026-04-05 02:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2019-05-14/pdf/2019-09866.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2019-09866.pdf?1557751519","publication_date":"2019-05-14","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2019/05/14/2019-09866.txt","regulation_id_number_info":{"2120-AA64":{"issue":"202410","html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202410&RIN=2120-AA64&operation=OPERATION_EXPORT_XML","priority_category":"Routine and Frequent"}},"regulation_id_numbers":["2120-AA64"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Regulatory Evaluation","document_id":"FAA-2019-0323-0003"},{"title":"Supporting AD Documents","document_id":"FAA-2019-0323-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":3,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2019-0323","supporting_documents_count":2,"docket_id":"FAA-2019-0323","document_id":"FAA-2019-0323-0001","regulation_id_number":"2120-AA64","title":"2019-NM-026-AD\nThe Boeing Company Model 737-800 series airplanes","checked_regulationsdotgov_at":"2023-02-28T19:18:32Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":21279,"subtype":null,"title":"Airworthiness Directives; The Boeing Company Airplanes","toc_doc":"The Boeing Company Airplanes","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":84}
