BULATSA is the Bulgarian Air Traffic Services Authority, a branch of the Bulgarian Civil Aviation Administration responsible for air traffic management within Bulgaria's airspace.


The establishment of BULATSA is the result of a chain of events in the history of Bulgarian civil aviation. In 1946 a Directorate on Air Communications was established subordinated to the Council of Ministers. In 1948 the Law on Aviation came into force and it went through a series of amendments over the years until the Civil Aviation Act of the Republic of Bulgaria evolved. As a result of the increased requirements to civil aviation in 1966 the State Economic Association "Bulgarian Civil Aviation" was established. In 1967 the Republic of Bulgaria ratified the 1944 Chicago Convention on International Civil Aviation and became a member of the International Civil Aviation Organisation. BULATSA is an EUROCONTROL member since 1997.
