{"abstract":"We are adopting a new airworthiness directive (AD) for certain Rockwell Collins, Inc. TSS-4100 Traffic Surveillance System Processing Units that incorporate TSSA-4100 Field Loadable Software (FLS) Rockwell Collins part numbers 810-0052-002/-003/-010/-011/-012/-100/-101 and are installed on airplanes. This AD was prompted by five instances of air traffic control observing coasting (extrapolated stale data) of automatic dependent surveillance-broadcast data (position/velocity data). This AD requires installing the TSSA-4100 FLS upgrades on the TSS-4100 units. We are 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/2017/11/15/2017-24066.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"82 FR 52827","comment_url":"https://www.regulations.gov/commenton/FAA-2017-0659-0008","comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective December 20, 2017.","disposition_notes":null,"docket_ids":["Docket No. FAA-2017-0659","Product Identifier 2017-CE-014-AD","Amendment 39-19094","AD 2017-22-14"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supporting AD Documents","document_id":"FAA-2017-0659-0009"},{"title":"U.S. DOT/FAA - Supporting AD Documents","document_id":"FAA-2017-0659-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2017-11-15","updated_at":"2024-11-07T00:42:19.605-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2017-0659-0008","allow_late_comments":true,"id":"FAA-2017-0659-0008","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2017-0659","title":"Rockwell Collins TSS-4100 field loadable software upgrade"}],"document_number":"2017-24066","effective_on":"2017-12-20","end_page":52830,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2017/11/15/2017-24066.xml","html_url":"https://www.federalregister.gov/documents/2017/11/15/2017-24066/airworthiness-directives-rockwell-collins-inc-traffic-surveillance-system-processing-unit","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2017-24066?publication_date=2017-11-15","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2017-11-15/2017-24066/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":1292,"last_updated":"2026-04-04 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2017-11-15/pdf/2017-24066.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2017-24066.pdf?1510667124","publication_date":"2017-11-15","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2017/11/15/2017-24066.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":"U.S. DOT/FAA - Supporting AD Documents","document_id":"FAA-2017-0659-0009"},{"title":"U.S. DOT/FAA - Supporting AD Documents","document_id":"FAA-2017-0659-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":0,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2017-0659","supporting_documents_count":2,"docket_id":"FAA-2017-0659","document_id":"FAA-2017-0659-0008","regulation_id_number":"2120-AA64","title":"Rockwell Collins TSS-4100 field loadable software upgrade","checked_regulationsdotgov_at":"2024-11-08T01:00:07Z"},"regulations_dot_gov_url":"https://www.regulations.gov/commenton/FAA-2017-0659-0008","significant":false,"signing_date":null,"start_page":52827,"subtype":null,"title":"Airworthiness Directives; Rockwell Collins, Inc.
