{"abstract":"The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757-200, -200PF, and -300 series airplanes, powered by Pratt & Whitney PW2000 series engines. This AD requires repetitive inspections for loose or damaged components of the support brackets and associated fasteners for the hydraulic lines located in the nacelle struts, and any related investigative and corrective actions. This AD results from reports of damage and subsequent failure of the support brackets and associated fasteners for the hydraulic lines located internal to the upper fairing cavity of the nacelle struts. We are issuing this AD to prevent such failure, which, in conjunction with sparking of electrical wires, failure of seals that would allow flammable fluids to migrate to compartments with ignition sources, or overheating of the pneumatic ducts beyond auto-ignition temperatures, could result in an uncontained fire.","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/2005/10/13/05-20264.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"70 FR 59644","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD becomes effective November 17, 2005.","disposition_notes":null,"docket_ids":["Docket No. FAA-2005-20137","Directorate Identifier 2004-NM-96-AD","Amendment 39-14338","AD 2005-20-41"],"dockets":[],"document_number":"05-20264","effective_on":"2005-11-17","end_page":59647,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2005/10/13/05-20264.xml","html_url":"https://www.federalregister.gov/documents/2005/10/13/05-20264/airworthiness-directives-boeing-model-757-200--200pf-and--300-series-airplanes-powered-by-pratt-and","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/05-20264?publication_date=2005-10-13","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2005-10-13/05-20264/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":35,"last_updated":"2026-04-04 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2005-10-13/pdf/05-20264.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2005-10-13","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2005/10/13/05-20264.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":"2011-11-12T17:19:18Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":59644,"subtype":null,"title":"Airworthiness Directives; Boeing Model 757-200, -200PF, and -300 Series Airplanes, Powered by Pratt & Whitney PW2000 Series Engines","toc_doc":"Boeing","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":70}
