'When the airline first entered the air carrier market and started using Koltsovo airport’s services, Aviaprad received a very warm welcome. At the same time, things grew less blissful in the fall of 2007 when the carrier’s debts kept growing yet the company was unable to come up with either a clear-cut paying-off schedule or restructuring proposals. Aviaprad’s debt reached more than 1 billion RUR in January 2008,’ RENOVA Group’s representative Andrei Shtorkh said to UrBC.
