Spirit AeroSystems is confident that it is managing the demands of Airbus A350 aerostructures production despite initial problems which contributed to assembly delays.
The US supplier admits that it has been performing catch-up work with the A350's crucial section 15, the centre fuselage to which the wings are mated.
Chief executive Jeff Turner, during an earnings call on 1 November, said the company had delivered two of the sections to Airbus.
He says the company is "in the throes" of section 15 manufacture, conceding it has "a lot of work on", particularly regarding the first four of these sections which were "behind in the process".
"So we've got a lot of travel work and a lot of extra work being done to stay ahead of the customer and help the customer get those airplanes through their production line," he says.
Spirit AeroSystems is also responsible for the front wing spar on the type, and Turner says this structure is "in a little bit better position".
But he is confident that the risk profile on the A350 is not dissimilar to that of other development programmes, and that Spirit's position is "well reserved and conservatively forecast".
