The first Airbus A350 yesterday performed some low speed taxi tests, but has not yet gone through the full program of ground tests needed to clear the aircraft for first flight.

MSN001 still has to perform high speed taxi trials, likely tomorrow, and could fly later this week if no last minute flaws are found.

The aircraft was still undergoing extensive flight test wiring installation late last week after the engines had been powered up for the first time on June 2. Taxi trials were originally planned for June 7, but that shifted somewhat.

It now appears doubtful that Airbus will be able to stick to a preliminary plan to fly on June 13, partly because disruptions by a French air traffic control strike are likely to still be felt, but those issues should be resolved on June 14.

Airbus is keen to fly the aircraft during the Paris air show, which is being held June 17-23, but that is subject to post-first flight analysis and clearance.

First flight will be followed by a 2,500-hr. test campaign involving five aircraft. Assembly of MSN002, the third test aircraft, started earlier this month.
