Jul.27 (GMM) David Coulthard is expecting the FIA to launch a probe into the "structural integrity" of Toyota's current formula one single seater.

The Scottish veteran, who drives for rivals Red Bull Racing, said that incidents involving the Cologne-designed TF108 can be compared with earlier this season, when the governing body looked into the integrity of the Adrian Newey-penned RB4 car.

Off the back of several incidents involving crumbling suspension pieces at both Sepang and Melbourne earlier this season, FIA stewards ordered Red Bull to explain in a detailed technical report how its car is safe enough to race.

In a section of his latest website column for the British broadcaster ITV entitled 'Double standard?', Coulthard pointed out that Toyota has now also had a run of apparent chassis problems.

Toyota confirmed last week that Timo Glock's heavy crash at Hockenheim had been tracked to the right-rear trackrod, while at Silverstone Jarno Trulli ended in the tyre barrier following a rear wing failure.

But Coulthard said: "I didn't hear of any investigation into the structural integrity of the Toyota -- but presumably that will happen because when we had a suspension breakage in Malaysia we came under the spotlight of the FIA in a way that was publicly uncomfortable for the team."
