Design and development

Construction started in 1937, but the first flight of the JDA-10M was in September 1939. After the beginning of the Second World War it was planned to transform airplane into a light bomber for military purposes. This work was halted by the Soviet occupation of Latvia in June 1940. Only one example was built and its fate remains unknown.

The VEF JDA-10M was of primarily wood construction, with fixed conventional landing gear.[1]
