Russian carrier Transaero insists it is still committed to taking Sukhoi Superjet 100 aircraft, adding that the two sides are working to meet conditions of the order.
Transaero signed for up to 16 of the 90-seat aircraft last year, for delivery from 2015, with six to arrive as an initial batch.
But it says there were several conditions attached to the deal and that, since it was signed, it has been working “jointly and constructively” with Sukhoi to fulfil them.
“This work is continuing,” it says, adding that it aims to secure high-quality airframes with good technical support.
Transaero admits that, as a result of the continuing negotiations, it has not yet applied to fund the Superjet order.
But the airline, which has strongly favoured Western-built types, points out that it has reached agreements with two Russian lessors for 12 Irkut MC-21s.
It already operates Tupolev Tu-214s and is using Tu-204 freighters.
