St Petersburg-based Rossiya is to modify other Antonov An-148 regional jets in its fleet as the airline continues to introduce the type to its operation.
The carrier on 24 August accepted the fifth serially built An-148, with the sixth of the type due to begin pre-delivery test flights at the Voronezh airframer VASO.
One of four An-148s, registered RA-61701, has been flown back to VASO to undergo performance reviews and refinement.
Rossiya says it will also successively transfer the other three previously received jets for technological improvements.
"These should remove the technical glitches and allow us to stretch the type's serviceability, up to deploying it on international routes," he says.
