Airbus expects to decide soon on a plan to boost widebody output to a rate of 11 aircraft a month even as it delays ramping up narrowbody production.

Airbus had been considering a single-aisle production rate increase to 44 aircraft a month, but has decided to hold off for the moment because of bottlenecks among Tier 2 suppliers. The situation is different for the A330, making a production boost there possible, says John Leahy, Airbus chief operating officer for customers. The company expects to reach a production rate of 10 widebodies per month this year.

Airbus COO Fabrice Bregier hints that a decision on the single-aisle side could wait until a rate of 42 aircraft per month is reached, which is expected next year. “It would be premature to do it now,” he notes.

One of the reasons Airbus is keen to boost production is because of its bulging backlog. The company booked 1,419 net orders last year and made 535 deliveries. And 2012 should see order intake move ahead of deliveries, with new orders forecast to reach 600-650, while deliveries of 570 aircraft are expected. The order intake should include about 30 A380s, matching the 2012 delivery target.

Output is only one of the deliberations for Airbus this year. The other is whether to launch an A330 winglet program. Leahy says studies have begun for both forward-fit and retrofit options. A decision is likely this year.

If the devices could yield a 2% fuel burn benefit, Leahy says such a program would likely move forward.

Not on the near-term agenda is the A380-900 program, a stretched version of the aircraft now on the market. Despite occasional customer interest, such a project would not likely emerge until the second half of the decade, says Airbus CEO Tom Enders. The focus now is on ramping up production. Profit-delivering aircraft will go to customers starting in 2015.
