The Aircraft Accident Investigation Unit (AAIU) was established in October 2001 in accordance with the provisions of: Annex 13 for aircraft accident and incident investigation to the Chicago Convention, Council Directive 94/56 establishing the fundamental principles governing the investigation of civil aviation accidents and incidents and Article 3 of the Regulation No:13 of the Ministry of Transport, Information Technology and Communications for aircraft accident investigation, dated 27 January 1999. In 2004 the Civil Aviation Act was revised and amended and Article 16 d was created which represents the legal provision for the establishment of the AAIU. The AAIU is completely independent from the Civil Aviation Authority and reports directly to the Minister of Transport, Information Technology and Communications of the Republic of Bulgaria.
