Air Sofia (Sofia) , Bright Aviation Services (BRW/Sofia), Scorpion Air (SPN/Sofia) and Vega Airlines (VEA/Plovdiv) have all lost their operator certificates and have been forced to cease operations. The Bulgarian aviation authorities decided to revoke the certificates as the carriers did not comply with EU safety standards. The operator certificate of Air Scorpio (SCU/Sofia) has been temporarily suspended while the only other Bulgarian cargo operator Heli Air (HLR/Sofia) is allowed to continue its operations outside the European Union but has been banned from European airspace.
