Believe me my friend when our second aircraft came from russia it took a lot of maintenance and a lot of sudden problems comming up in flight..... which where odd ,that took time to repair now after a couple of months its up to standards, after inspection the third aircraft was even in a worse condition than the second so management rejected it. Now they are looking for a 3th aircraft urgently because the market is there and trafficload is high.
btw it is not because an aircaft is 20 years old it should be in bad condition.
