{"abstract":"This special condition is issued for Supplemental Type Certificate (STC), Project Number ST2902RC-R, for the installation of a Pratt and Whitney PT6-67D Turbine Engine on Global Helicopter Technology Inc. (GHTI), Restricted Category, U.S. Army military surplus helicopters, Model UH-1H, type certificated under type certificate (TC) R00002RC. The installation of the PT6-67D on the Restricted Category UH-1H will have a novel or unusual design feature associated with the installation of the Full Authority Digital Engine Control (FADEC). The applicable airworthiness regulations do not contain adequate or appropriate safety standards to protect systems that perform critical control functions from the effects of a high-intensity radiated field (HIRF). This special condition contains the additional safety standards that the Administrator considers necessary to ensure that critical control functions of systems will be maintained when exposed to HIRF.","action":"Final special condition; 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/2007/11/16/07-5698.html","cfr_references":[{"chapter":null,"citation_url":null,"part":21,"title":14},{"chapter":null,"citation_url":null,"part":29,"title":14}],"citation":"72 FR 64529","comment_url":null,"comments_close_on":"2008-01-15","correction_of":null,"corrections":[],"dates":"The effective date of this special condition is November 7, 2007.
