PROGRAMME: Developed by KnAAPO at Komsomolsk as single-engined version of Beriev Be-103 Bekas for Russian Federation market. First aircraft under construction at KnAAPO by September 2001, when designation first announced. Prototype exhibited unflown at Gelendzhik Gidroavia Salon, September 2002. First flight 16 October 2002. Factory trials had been completed by April 2003; certification to Russian AP-23 and FAR Pt 23 due 2003, for first deliveries in 2004, although this timetable not met. Prototype transferred to KnAAPO Sports & Technical Club for experimental service. Reported in 2004 to be undergoing redesign to eliminate buffeting.
