US lessor International Lease Finance (ILFC) has pushed back by one year the deliveries of its Airbus A380 aircraft.
The leasing giant has 10 of the double-deck aircraft on order.
It was originally scheduled to take the first five in 2013, with another three in 2014 and the remaining pair arriving in 2015.
But in its latest year-end regulatory filing the lessor states that, subsequent to 31 December 2009, its A380 order was deferred.
"We delayed the deliveries of the A380s, each by one year," it says. It has not given a specific reason for the decision.
The aircraft had been subject to a cancellation option up to 30 June this year, but ILFC says that this deadline has been extended by six months to 31 December.
ILFC has agreed to fit four of its A380s with Engine Alliance GP7200 engines but the powerplants for the other six remain undecided.
Less than a year ago the lessor's then-chief, Steven Udvar-Hazy, reportedly admitted to doubts over the future of the company's A380 order.
ILFC remains the only leasing company with the A380 in its backlog. It originally planned to take five freighters as part of the order for 10, but switched them to passenger airframes in 2006.
