{"abstract":"The FAA adopts a new airworthiness directive (AD) for General Machine--Diecron, Inc. (GMD) actuator nut assembly, part number (P/N) GMD115-810029-17 and P/N GMD115-810029-23, that are installed on certain Raytheon Aircraft Company (Raytheon) (formerly Beech) airplanes that are not equipped with a hydraulic main landing gear (MLG) or modified to a hydraulic MLG. This AD requires you to determine by maintenance records check and/or inspection whether any actuator nut assembly, P/N GMD115-810029-17 or P/N GMD115-810029-23, is installed on the right main MLG actuator, and, if installed, requires you to replace it with a new actuator nut assembly, P/N GMD115-810029-23B or FAA- approved equivalent P/N. This AD results from several reports of failures of the actuator nut assembly, P/N GMD115-810029-17 and P/N GMD115-810029-23. We are issuing this AD to prevent failure of the actuator nut assembly for the right MLG actuator, which could result in failure of the MLG. This failure could prevent the extension or retraction of the MLG.","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/2006/06/16/06-5429.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"71 FR 34804","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD becomes effective on July 28, 2006.","disposition_notes":null,"docket_ids":["Docket No. FAA-2005-23334","Directorate Identifier 2005-CE-53-AD","Amendment 39-14651","AD 2006-12-25"],"dockets":[],"document_number":"06-5429","effective_on":"2006-07-28","end_page":34806,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2006/06/16/06-5429.xml","html_url":"https://www.federalregister.gov/documents/2006/06/16/06-5429/airworthiness-directives-general-machine-diecron-inc-actuator-nut-assembly-for-the-right-main","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/06-5429?publication_date=2006-06-16","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2006-06-16/06-5429/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":97,"last_updated":"2026-08-24 16:15:16 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2006-06-16/pdf/06-5429.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2006-06-16","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2006/06/16/06-5429.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":{"checked_regulationsdotgov_at":"2011-11-12T19:37:23Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":34804,"subtype":null,"title":"Airworthiness Directives; General Machine-Diecron, Inc.
