Worked for DAR before Second World War. From 1946 built the LAZ-7M; LAZ-8 four-seat taxi; LAZ-11 ambulance version of -8; and LAZ-12 single-seat aerobatic aircraft. All except the LAZ-7 sporting monoplane were built in prototype form only. The LAZ-1 OH light helicopter was abandoned before completion. All powered aircraft production in Bulgaria ceased in 1961.
