{"abstract":"The FAA is superseding Airworthiness Directive (AD) 2013-26-01 for all CFM International, S.A. (CFM) CFM56-3 and CFM56-7B model turbofan engines with a certain accessory gearbox assembly (AGB) not equipped with a dynamic oil seal assembly in the handcranking pad. AD 2013-26-01 required an independent inspection to verify re-installation of the handcranking pad cover after removal of the pad cover for maintenance. This AD was prompted by a dual engine loss of oil event and 42 prior events of total loss of engine oil during flight. This AD requires independent inspection to verify re-installation of the AGB handcranking pad cover after maintenance. This AD also requires the replacement of the affected AGB as a terminating action to the inspection requirement. The FAA is issuing this AD to address the unsafe condition on these products.","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/2022/02/15/2022-03039.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"87 FR 8402","comment_url":"https://www.regulations.gov/commenton/FAA-2021-0259-0010","comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective March 22, 2022.","disposition_notes":null,"docket_ids":["Docket No. FAA-2021-0259","Project Identifier AD-2020-01128-E","Amendment 39-21900","AD 2022-02-03"],"dockets":[{"supporting_documents":[{"title":"Airworthiness Directives: CFM International, S.A.
