This is a copy and paste from a press release issued by Airbus…
Airbus has successfully completed the main structural assembly and system connection of A350 XWB ‘MSN1’ – the first flight-test aircraft. The aircraft is depicted here on its wheels for the very first time moving out of the main assembly hall (Station 40) at the recently inaugurated “Roger Béteille” A350 XWB Final Assembly Line in Toulouse. It then entered the adjacent indoor ground test station (Station 30).
The assembly work performed in Station 40 included the successful electrical power-on of the aircraft’s entire fuselage and wings. Soon work in Station 30 will start by testing the aircraft’s hydraulic system, followed by the full electric and hydraulic power-on of the aircraft which will be completed by around the end of the year. This will mark the start of several weeks of comprehensive functional system testing.
After the A350 XWB MSN1 exits station 30, the aircraft will go through a series of extensive production and certification / development tests, be painted and have its engines installed. It will then be delivered to the flight-line and be readied for its first flight in mid-2013.
UPDATE: Airbus has confirmed that the front doors on the A350, as shown in this photo, will be closed on the ground during normal operations. “The forward set of doors only will be open when the gear is being extended or retracted,” Airbus stated to AirlineReporter.com. “The reason that they are open in this picture is that the aircraft is not hydraulically “active” at the point when the picture was snapped and there was no reason to close the doors for the short road trip.”
