Croatian Civil Aviation Agency is a legal entity, which under its public authority performs tasks stipulated by the Air Traffic Act, as an activity of special interest to the Republic of Croatia, as well as all other tasks in accordance with regulations adopted pursuant to the Air Traffic Act.

The Agency is an expert organization which, in line with the rapid technical and technological development in the civil aviation, monitors and implements international standards mandatory for fulfilment of Croatia's obligations in the civil air traffic safety and security field.

Republic of Croatia, as a European Union member state, has the obligation of complete harmonization of the Croatian national legislation in the air traffic field with the EU's acquis communautaire. With Croatia's accession to the European Union, EU's acquis communautaire in the field of civil aviation became applicable in Croatia superseding the national legislation.
