Williams has been forced to curtail its running on the second day of Formula 1's pre-season test running in Barcelona after a spin for rookie driver Lance Stroll during the morning session.
Stroll, 18, enjoyed his first public F1 running this morning behind the wheel of the Williams FW40, but suffered a spin at Turn 9 that caused damage to the car.
Although the accident was "entirely innocuous," according to head of performance engineering Rob Smedley, parts need to be returned to Williams' factory in England, forcing the team to end its day two running prematurely.
"Lance was on lap six of his second run when he had a spin. The grip was particularly low and so he spun and went through the gravel backwards," Smedley explained.
"We’re having to send some composite parts back to the factory, which will be back with us at some point tomorrow. We’re doing the utmost we can now to get back out on track at the earliest opportunity tomorrow.
"We will be able to recover the programme in the coming days."
"It is still early days and I have only done a handful of laps. I am just getting to grips with the FW40, and there is still a lot of time ahead of us," Stroll added, having completed 12 laps in total.
"It was good to finally get behind the wheel to just get a feel for it. Like I said, it is still early days, so I need to do a lot more running before I know exactly where I am and where the car is at.
"I will have a much better picture once we have more laps under our belts, but it was good to break the ice and I am looking forward to some more running."
Stroll finished the morning session in seventh place on the leaderboard.
