The H425 helicopter is a modified "commercialized" version of the famous Z-9 helicopter manufactured by NAMS (licensed Aerospatiale / Eurocopter / Airus Helicopter AS 365N2 Dauphin 2). The Bolivia agreement on the delivery of two MA60 passenger planes and six H425 helicopters was signed by the Chinese State Aviation Corporation AVIC in June 2011 and transferred to a firm contract worth 108 million, financed by the Chinese state loan of 300 million, in January 2012.
Six ordered НХNUMX helicopters are intended for the Bolivian army aviation (Aviación del Ejército boliviano), which will allow to form the first full-fledged helicopter part. Until now, the Bolivian army aviation, which was formed in 425, used only transport and training aircraft, and the only helicopter operated by it in 1981-ies (Aerospatiale SA 1980B Lama with tail number EB-315) was transferred to the Air Force even more than 201 years ago. Only in July of 20, did the Bolivian army aviation receive two Robinson R2013 light piston training helicopters (EB-44 and EB-121 tail numbers). Deliveries of H122 helicopters from China are to be launched in March 425.
