{"abstract":"The FAA is revising an existing airworthiness directive (AD) for certain Boeing Model 757-200 and -200PF series airplanes. That AD currently requires inspections, adjustments, and functional checks of the engine thrust reverser system; and modification of the engine thrust reverser directional control valve. That AD also requires installation of an additional thrust reverser locking feature and periodic functional tests of the locking feature following installation. This new AD retains the requirements of the existing AD, but removes certain tests and inspections for certain airplanes. This AD is prompted by a determination of an error in the existing AD. We are issuing this AD to prevent deployment of a thrust reverser in flight and subsequent reduced controllability of the airplane.","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/2005/01/13/05-536.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"70 FR 2330","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective January 28, 2005.","disposition_notes":null,"docket_ids":["Docket No. FAA-2005-20009","Directorate Identifier 2003-NM-220-AD","Amendment 39-13937","AD 94-01-10 R2"],"dockets":[],"document_number":"05-536","effective_on":"2005-01-28","end_page":2333,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2005/01/13/05-536.xml","html_url":"https://www.federalregister.gov/documents/2005/01/13/05-536/airworthiness-directives-boeing-model-757-200-and--200pf-series-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/05-536?publication_date=2005-01-13","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2005-01-13/05-536/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":364,"last_updated":"2026-04-04 14:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2005-01-13/pdf/05-536.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2005-01-13","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2005/01/13/05-536.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":{"checked_regulationsdotgov_at":"2011-11-12T14:22:57Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":2330,"subtype":null,"title":"Airworthiness Directives; Boeing Model 757-200 and -200PF Series Airplanes","toc_doc":"Boeing","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":70}
