{"abstract":"The FAA is proposing to amend the aircraft turbine engine type certification standards to reflect recent analysis of the threat flocking birds present to turbine engine aircraft. These proposed changes would also harmonize FAA, Joint Aviation Authority (JAA), and European Aviation Safety Agency (EASA) bird ingestion standards for aircraft turbine engines type certificated by the United States and the JAA/EASA countries, and simplify airworthiness approvals for import and export. These proposed changes are necessary to establish uniform international standards that provide an adequate level of safety for aircraft turbine engines with respect to the current large flocking bird threat.","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/2006/07/20/E6-11373.html","cfr_references":[{"chapter":null,"citation_url":null,"part":33,"title":14}],"citation":"71 FR 41184","comment_url":null,"comments_close_on":"2006-09-18","correction_of":null,"corrections":[],"dates":"Send your comments on or before September 18, 2006.","disposition_notes":null,"docket_ids":["Docket No. FAA-2006-25375","Notice No. 06-09"],"dockets":[],"document_number":"E6-11373","effective_on":null,"end_page":41192,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2006/07/20/E6-11373.xml","html_url":"https://www.federalregister.gov/documents/2006/07/20/E6-11373/airworthiness-standards-engine-bird-ingestion","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/E6-11373?publication_date=2006-07-20","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2006-07-20/E6-11373/mods.xml","not_received_for_publication":null,"page_length":9,"page_views":{"count":305,"last_updated":"2026-06-26 20:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2006-07-20/pdf/E6-11373.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2006-07-20","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2006/07/20/E6-11373.txt","regulation_id_number_info":{"2120-AI73":null},"regulation_id_numbers":["2120-AI73"],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-11-12T19:47:29Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":41184,"subtype":null,"title":"Airworthiness Standards; Engine Bird Ingestion","toc_doc":"Engine bird ingestion","toc_subject":"Airworthiness standards:","topics":["Air transportation","Aircraft","Aviation safety","Safety"],"type":"Proposed Rule","volume":71}
