{"abstract":"We are adopting a new airworthiness directive (AD) for certain Mooney Aviation Company, Inc. (Mooney) Models M20R and M20TN airplanes. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires inspecting the tail pitch trim assembly for correct positioning and proper attachment and inspecting the Huck Bolt fasteners for proper security with repair as necessary. The AD also requires sending the inspection results to the FAA and Mooney. This AD was prompted by a report of an incident on a Mooney Model M20TN airplane regarding failure of the tail pitch trim assembly, which could result in loss of control. We are issuing this AD to correct 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/2012/02/29/2012-4176.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"77 FR 12179","comment_url":"http://www.regulations.gov/commenton/FAA-2012-0182-0001","comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective February 29, 2012 to all persons except those persons to whom it was made immediately effective by Emergency AD 2012-03-52, issued on February 10, 2012, which contained the requirements of this amendment.","disposition_notes":null,"docket_ids":["Docket No. FAA-2012-0182","Directorate Identifier 2012-CE-005-AD","Amendment 39-16958","AD 2012-03-52"],"dockets":[],"document_number":"2012-4176","effective_on":"2012-02-29","end_page":12182,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2012/02/29/2012-4176.xml","html_url":"https://www.federalregister.gov/documents/2012/02/29/2012-4176/airworthiness-directives-mooney-aviation-company-inc-mooney-airplanes","images":{"ER29FE12.000":{"large":"https://img.federalregister.gov/ER29FE12.000/ER29FE12.000_large.png","medium":"https://img.federalregister.gov/ER29FE12.000/ER29FE12.000_medium.png","original_size":"https://img.federalregister.gov/ER29FE12.000/ER29FE12.000_original_size.png"}},"images_metadata":{"ER29FE12.000":{"large":{"identifier":"ER29FE12.000","content_type":"image/png","size":67614,"width":776,"sha":"2b10cc2ad268f6859694f0e74feed9a8","url":"https://img.federalregister.gov/ER29FE12.000/ER29FE12.000_large.png","height":555},"medium":{"identifier":"ER29FE12.000","content_type":"image/png","size":16504,"width":365,"sha":"4db7f605e68977258f7766b0a80525b4","url":"https://img.federalregister.gov/ER29FE12.000/ER29FE12.000_medium.png","height":261},"original_size":{"identifier":"ER29FE12.000","content_type":"image/png","size":547014,"width":2764,"sha":"ed737f4c5cf2509e292ad2f000e91155","url":"https://img.federalregister.gov/ER29FE12.000/ER29FE12.000_original_size.png","height":1976}}},"json_url":"https://www.federalregister.gov/api/v1/documents/2012-4176?publication_date=2012-02-29","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2012-02-29/2012-4176/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":656,"last_updated":"2026-10-25 02:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2012-02-29/pdf/2012-4176.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2012-04176.pdf?1330464892","publication_date":"2012-02-29","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2012/02/29/2012-4176.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":[{"title":"U.S. DOT/FAA - See Attachments","document_id":"FAA-2012-0182-0002"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2012-0182","supporting_documents_count":1,"docket_id":"FAA-2012-0182","regulation_id_number":null,"title":"2012-CE-005-AD","checked_regulationsdotgov_at":"2023-03-01T18:08:55Z"},"regulations_dot_gov_url":"http://www.regulations.gov/commenton/FAA-2012-0182-0001","significant":false,"signing_date":null,"start_page":12179,"subtype":null,"title":"Airworthiness Directives; Mooney Aviation Company, Inc.
