After landing on the runway, direction 12, they noticed that there are construction machines in front of them, and the air traffic controller informed them that they have landed on the closed portion of the runway where construction works were being performed. At the time of the serious incident, three crew members and seven passengers were on board the aircraft, none of whom were injured, and no material damage occurred. The immediate cause of the serious incident in question was failure to identify the active portion of the runway and the closed portion of the runway by the commander of the aircraft. AIA issued safety recommendations to Dubrovnik Airport, Croatia Control (CC), aircraft operator - company Van Air Europe, and Croatian Civil Aviation Agency (CCAA). 1.
