Williams resume testing with new parts

Kazuki Nakajima was unhurt when his FW30 speared off the track at Turn 1 shortly before noon. Williams pinned the cause of the crash to a front wing failure, caused by a crack in the stay mounting that occurred a few corners prior to the Japanese's high-speed accident.

Using team owner Frank Williams's private plane, the team flew new parts this morning from Grove to Barcelona, and both drivers were back on track shortly before midday - Nico Rosberg completing six laps and Nakajima three.

Speaking about his crash yesterday, the Japanese rookie told autosport.com: "I was on full throttle when suddenly the downforce went to the back, as I went into the first corner.

"I didn't know what was happening, and I could see where I was going - the run-off area is not that big, and I could see I was going for the wall.

"This time last year I had a huge accident in the back of the track; that was then the biggest accident [I ever had]. But then, I was going completely backwards - so maybe it is better if you don't see what is in front of you...

"But this one is pretty big, and I still didn't know if it was my fault or not when I returned to the pits. Later I could see from the data [that it was a mechanical failure]. So I am OK, no problems. I had my physio look at my neck too, and it seems fine."

Nakajima added that the car's monocoque remained intact, and despite the lost mileage he remained confident in the car's performance.

"The car seems good; it is fast, and as I felt initially it seems to have better traction out of corner despite no traction control. We did miss some mileage [because of the failure], but we will continue to learn this car and make it better."
