{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787 series airplanes. This proposed AD was prompted by reports that the nose landing gear (NLG) retracted while the airplane was on the ground with weight on wheels, due to the installation of a NLG downlock pin in an incorrect location. This proposed AD would require installing an insert to prevent installation of the pin in the incorrect location. The FAA is 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/2019/07/23/2019-15519.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"84 FR 35352","comment_url":null,"comments_close_on":"2019-09-06","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by September 6, 2019.","disposition_notes":null,"docket_ids":["Docket No. FAA-2019-0494","Product Identifier 2019-NM-051-AD"],"dockets":[{"supporting_documents":[{"title":"Regulatory Evaluation and Record of Discussion","document_id":"FAA-2019-0494-0002"}],"agency_name":"FAA","documents":[{"comment_count":4,"comment_start_date":"2019-07-23","updated_at":"2023-02-28T21:05:20.669-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2019-0494-0001","allow_late_comments":null,"id":"FAA-2019-0494-0001","comment_end_date":"2019-09-07","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2019-0494","title":"2019-NM-051-AD\nThe Boeing Company Model 787-8, 787-9, and 787-10 airplanes"}],"document_number":"2019-15519","effective_on":null,"end_page":35354,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2019/07/23/2019-15519.xml","html_url":"https://www.federalregister.gov/documents/2019/07/23/2019-15519/airworthiness-directives-the-boeing-company-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2019-15519?publication_date=2019-07-23","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2019-07-23/2019-15519/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":4691,"last_updated":"2026-04-04 12:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2019-07-23/pdf/2019-15519.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2019-15519.pdf?1563799517","publication_date":"2019-07-23","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2019/07/23/2019-15519.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 and Record of Discussion","document_id":"FAA-2019-0494-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":4,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2019-0494","supporting_documents_count":1,"docket_id":"FAA-2019-0494","document_id":"FAA-2019-0494-0001","regulation_id_number":"2120-AA64","title":"2019-NM-051-AD\nThe Boeing Company Model 787-8, 787-9, and 787-10 airplanes","checked_regulationsdotgov_at":"2023-03-01T02:05:19Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":35352,"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}
