{"abstract":"This document reopens the comment period of an earlier proposed airworthiness directive (AD) that would supersede AD 98-05-04, which currently requires repetitively inspecting the front and rear wood spars for damage, including installing any necessary inspection holes, on certain American Champion Aircraft Corporation (ACAC) Model 8GCBC airplanes; and repairing or replacing any damaged wood spar. Damage is defined as cracks; compression cracks; longitudinal cracks through the bolt holes or nail holes; or loose or missing nails. The proposed AD would retain the actions of AD 98-05-04; would extend these actions to ACAC 7, 8, and 11 series airplanes; and would incorporate alternative methods of accomplishing the actions. Since issuing the NPRM, the Federal Aviation Administration (FAA) received a comment requesting additional time to comment on the proposed AD. The FAA concurs that the comment period for the proposal should be reopened and the public should have additional time to comment.","action":"Notice of proposed rulemaking (NPRM); Reopening of the comment period.","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/1999/08/04/99-20062.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"64 FR 42297","comment_url":null,"comments_close_on":"1999-09-10","correction_of":null,"corrections":[],"dates":"Comments must be received on or before September 10, 1999.","disposition_notes":null,"docket_ids":["Docket No. 98-CE-121-AD"],"dockets":[],"document_number":"99-20062","effective_on":null,"end_page":42300,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":null,"html_url":"https://www.federalregister.gov/documents/1999/08/04/99-20062/airworthiness-directives-american-champion-aircraft-corporation-7-8-and-11-series-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/99-20062?publication_date=1999-08-04","mods_url":"https://www.govinfo.gov/metadata/granule/FR-1999-08-04/99-20062/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":20,"last_updated":"2026-10-23 14:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-1999-08-04/pdf/99-20062.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"1999-08-04","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/1999/08/04/99-20062.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":"2011-09-21T07:49:47Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":42297,"subtype":null,"title":"Airworthiness Directives; American Champion Aircraft Corporation 7, 8, and 11 Series Airplanes","toc_doc":null,"toc_subject":null,"topics":[],"type":"Proposed Rule","volume":64}
