Independence was declared on 25 June 1991. Following that, Adria was facing an entirely new set of circumstances. On 28 June 1991, Yugoslav Federal Air Force attacked Adria's hangar, causing serious damage to four aircraft, the building, and vehicles. An Airbus A320, less than a year old, was heavily damaged and was flown to Toulouse later that year for almost a year of repairs. In addition, two Dash-7 and 1 DC-9-30 were damaged as well, while other planes escaped damage after being flown just hours earlier to the nearest airport of Klagenfurt. Adria was very handicapped that year because of the insurance and registration issues.
