{"abstract":"This amendment corrects information in an existing airworthiness directive (AD), applicable to certain Boeing Model 727 series airplanes, that currently requires that the FAA-approved maintenance inspection program be revised to include inspections that will give no less than the required damage tolerance rating for each Structural Significant Item (SSI), and repair of cracked structure. The actions specified in that AD are intended to ensure the continued structural integrity of the entire Boeing Model 727 fleet. This amendment corrects the requirements of the current AD by allowing operators not to change their programs if they determine that the existing inspections are effective for the new or affected SSI. This amendment is prompted by a review of the requirements of the existing AD.","action":"Final rule; correction.","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/1999/01/07/99-183.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"64 FR 989","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective June 23, 1998.","disposition_notes":null,"docket_ids":["Docket No. 96-NM-263-AD","Amendment 39-10983","AD 98-11-03 R1"],"dockets":[],"document_number":"99-183","effective_on":"1998-06-23","end_page":991,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":null,"html_url":"https://www.federalregister.gov/documents/1999/01/07/99-183/airworthiness-directives-boeing-model-727-series-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/99-183?publication_date=1999-01-07","mods_url":"https://www.govinfo.gov/metadata/granule/FR-1999-01-07/99-183/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":18,"last_updated":"2026-04-05 02:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-1999-01-07/pdf/99-183.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"1999-01-07","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/1999/01/07/99-183.txt","regulation_id_number_info":{"2120-AA64":{"issue":"202504","html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202504&RIN=2120-AA64&operation=OPERATION_EXPORT_XML","priority_category":"Routine and Frequent"}},"regulation_id_numbers":["2120-AA64"],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-09-20T22:36:46Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":989,"subtype":null,"title":"Airworthiness Directives; Boeing Model 727 Series Airplanes","toc_doc":null,"toc_subject":null,"topics":[],"type":"Rule","volume":64}
