I read that Armavia has financial problems and economy issues are true reason for effort to return the a/c. As far as I know, there is the only one safety issue at first several SSJ - some sensor in climatisation system - if not absolute accurate mounting an cabling it gives false alarm of dehermetisation of cabine.
There are several non technical problems for foreign air companies - for example, when flying from Armenia to Russia for technical check they reportedly wait 2 days for Russian customs formalities. Russia also have not a scheme of financing the supply of a/c to a foreign companies by providing government guarantees for lower rates for loans.
It could be only teething.
