Sukhoi is considering an alternative recipient for a Superjet 100 originally due for delivery to Armavia, after the carrier appeared to postpone plans to take a second example.
Armavia, which became the first operator of the Superjet in April last year, was supposed to take a second in the first half of 2012.
Ulyanovsk-based Spektr-Avia painted the aircraft, already named after movie actor Frunzik Mkrtchyan, in Armavia's colours in March ahead of handing it over to the carrier which planned to put it into service in April.
But Sukhoi Civil Aircraft president Vladimir Prisyazhnyuk says Armavia cancelled the acceptance ceremony, scheduled for 22 June, at short notice and asked for a two-week hiatus.
Sukhoi customer relations chief Igor Syrtsov, speaking at the Farnborough air show, said: "They have not accepted a funding scheme proposed by Vnesheconombank and are currently deciding whether it is worth borrowing funds from other lenders," he says.
Armavia said, on 9 July, that it had not come to terms with the airframer on aircraft pricing. But Prisyazhnyuk believes the door is still open for further negotiations, and adds that alternative customers - such as Tomsk Avia - are prepared to acquire the aircraft.
