{"abstract":"The FAA is superseding Airworthiness Directive (AD) 2019-16- 05, which applied to all The Boeing Company Model 777 airplanes. AD 2019-16-05 required identifying the part number, and the serial number if applicable, of the Captain's and First Officer's seats, and applicable on-condition actions for affected seats. This AD was prompted by reports of uncommanded fore/aft movement of the Captain's and First Officer's seats. This AD retains the requirements of AD 2019- 16-05 and adds an inspection of previously omitted part numbers. The FAA is issuing this AD to address the unsafe condition on these products.","action":"Final rule.","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/2024/09/09/2024-20110.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"89 FR 72976","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective October 15, 2024.","disposition_notes":null,"docket_ids":["Docket No. FAA-2023-1879","Project Identifier AD-2023-00286-T","Amendment 39-22794","AD 2024-15-03"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2023-1879-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2024-09-09","updated_at":"2024-09-09T09:56:29.053-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2023-1879-0006","allow_late_comments":false,"id":"FAA-2023-1879-0006","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2023-1879","title":"AD-2023-00286-T;
