The DAR-9 Siniger, was a trainer produced in Bulgaria during World War II.
To provide the Bulgarian Air Force with a modern trainer, DAR took out a licence to build the Focke-Wulf Fw 44J.
The first series, powered by a Siemens-Halske Sh 14 radial engine, was built at the DAR factory, but subsequent series were built at the DSF (Derzhavna Samoletna Fabrika)[1] Surviving aircraft in 1948 were re-engined with Walter Minor 6.III inline engines due to difficulty in procuring spares and the poor condition of the Siemens-Halske engines.
Nine surplus DAR 9s were transferred to the Yugoslavian Air Force in 1947, withdrawn from service by 1958.
