{"abstract":"The FAA is adopting a new airworthiness directive (AD) for certain Pratt & Whitney (P&W) PW1500G and PW1900G model turbofan engines. This AD was prompted by an analysis of an event involving an International Aero Engines AG (IAE) V2533-A5 model turbofan engine, which experienced an uncontained failure of a high-pressure turbine (HPT) 1st-stage disk that resulted in high-energy debris penetrating the engine cowling. This AD requires removing certain HPT 1st-stage and HPT 2nd-stage disks from service and replacing with parts eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.","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/2022/01/12/2022-00414.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"87 FR 1664","comment_url":"https://www.regulations.gov/commenton/FAA-2021-1182-0001","comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective January 27, 2022.","disposition_notes":null,"docket_ids":["Docket No. FAA-2021-1182","Project Identifier AD-2021-01393-E","Amendment 39-21902","AD 2022-02-05"],"dockets":[{"supporting_documents":[],"agency_name":"FAA","documents":[{"comment_count":1,"comment_start_date":"2022-01-12","updated_at":"2024-11-06T20:56:43.736-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2021-1182-0001","allow_late_comments":true,"id":"FAA-2021-1182-0001","comment_end_date":"2022-03-01","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":0,"id":"FAA-2021-1182","title":"AD-2021-01393-E Pratt & Whitney PW1000 series turbofan engines; Removal of HPT disks"}],"document_number":"2022-00414","effective_on":"2022-01-27","end_page":1666,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2022/01/12/2022-00414.xml","html_url":"https://www.federalregister.gov/documents/2022/01/12/2022-00414/airworthiness-directives-pratt-and-whitney-turbofan-engines","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2022-00414?publication_date=2022-01-12","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2022-01-12/2022-00414/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":637,"last_updated":"2026-04-04 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2022-01-12/pdf/2022-00414.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2022-00414.pdf?1641590124","publication_date":"2022-01-12","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2022/01/12/2022-00414.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":[],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":1,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2021-1182","supporting_documents_count":0,"docket_id":"FAA-2021-1182","document_id":"FAA-2021-1182-0001","regulation_id_number":"2120-AA64","title":"AD-2021-01393-E Pratt & Whitney PW1000 series turbofan engines; Removal of HPT disks","checked_regulationsdotgov_at":"2024-11-07T01:53:09Z"},"regulations_dot_gov_url":"https://www.regulations.gov/commenton/FAA-2021-1182-0001","significant":false,"signing_date":null,"start_page":1664,"subtype":null,"title":"Airworthiness Directives; Pratt & Whitney Turbofan Engines","toc_doc":"Pratt and Whitney Turbofan Engines","toc_subject":"Airworthiness Directives:\n","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":87}
