Vitaly Petrov has said Caterham will have to take a 'close look' at his rear wing after it apparently failed at the end of second practice for this Sunday's Japanese Grand Prix.
Petrov was just about to complete his day's work, when the incident occurred at the end of the main straight, sending the Russian's CT01 into the gravel trap. While he fortunately escaped unharmed, the implications could have been a lot more serious.
Despite that scare though, he was still happy with his day and in the end he finished up 20th overall on the combined times, only a tenth or so off the sister car of Heikki Kovalainen.
“On the final lap in the afternoon session I went off in turn one after a problem with the rear wing. We'll have a very close look at what caused that so we can make sure it doesn't happen again,” Petrov remarked, “but apart from that I've had an OK Friday here in Japan.
“As the day's gone on the car has felt better on each run and it was pretty consistent on both tyre compounds. Having completed the runplans we set for FP1 and FP2 we've generated a lot of information for the guys to work on tonight and I think we're setting ourselves up OK for the weekend ahead.
“I came into the weekend with a cold that meant I had to miss some of yesterday's work on track. I've felt better today though and it's still good to have got through so much work in the car. We've run a lot of laps, doing aero work and testing a couple of new parts in the morning session and focusing on the tyres in FP2.”
Kovalainen meanwhile was also pleased with how things went, even if he did have to let reserve pilot, Giedo van der Garde use his car in first practice: “A pretty good session for me today in FP2. Having sat out FP1 we had a lot to get through in the afternoon session and we got through everything we'd planned,” said the Finn. “On the early runs on the hard tyres we had to work pretty hard to find a decent balance but we made a few changes and started heading in the right direction.
“On the soft tyres the car felt much better – it immediately felt balanced on the performance run and the degradation levels and balance on the long run were pretty manageable.
“We also finished with a time that puts some clear air between us and the cars behind [Marussia and HRT], so overall a pretty positive day,” Kovalainen concluded.
