While there are no overt red flags that came out of the Airbus press conference on Tuesday in Seville, the event marked a rhetorical course correction three and a half years out from first delivery of the A350 XWB.
Airbus has maintained that the A350-900 set to delivery to Qatar Airways in mid-2013 following a 15-month flight test program with five aircraft. A mid-2013 (May-August) delivery puts the A350’s first flight somewhere in the February to May 2012 time period, 25 to 28 months from now.
Tom Enders, Airbus CEO, established watch areas for parts of the aircraft’s design that are currently requiring additional (manpower) resources. While not a direct indication of any future issues, Enders has said the composite paneled fuselage and wing require extra attention:
We have today, more than 3000 Airbus engineers working on the program, plus another 3000 engineers with our partners. It is clear we need further ramp up in resources, we need further reinforcements, particularly in the fuselage and wing areas. We have important milestones ahead of us. Manufacturing has started, as you would imagine, as such a stage that program has a lot of challenges for us: New materials, processes, weight, schedule, just to mention the usual suspects.
Ultimately the time frame remains unchanged for first delivery, but Bloomberg/Newsweek reported that, Airbus Chief Operating Officer Fabrice Bregier said that the company has used “some of its margin” on the schedule of first deliveries.
According to the report, “challenges” have centered around “composite wings and fuselage, including systems installation and incorporating lightning strike protection.”
While not entirely unrelated, Airbus has also decided to alter its design strategy for the smaller A350-800 by offering a shrunken -900 rather than differentiated structure that would’ve optimized the weight of the aircraft. However, Airbus has opted to have a common landing gear, wing and fuselage while offering a 6000lb higher maximum zero fuel weight 250 nm increase in range, in exchange for “a couple of percent” fuel burn penalty with the added weight.
With resources needed on the wings and fuselage design of the -900, it is not entirely unsurprising that Airbus has chosen to focus on that design first rather than turn significant attention to removing unneeded structure from the -800.
The A350-800 is a total of 10 structural frames shorter (21 feet) than the -900, with six removed forward of the center wing box and four from the aft.
