Red Bull asked to supply technical report

Team principal Christian Horner, chief technology officer Adrian Newey and team manager Jonathan Wheatley met with the FIA race stewards immediately after second practice to explain what happened in Coulthard's crash this morning.

Coulthard ran off the track at Turn 13 after a track rod failure, but more worryingly then suffered major damage to the front suspension after it clouted a kerb at the bottom of the hill.

In the wake of another big suspension failure in Australia following Coulthard's crash with Felipe Massa, the race stewards wanted the team to explain what the situation with their car was.

Following the explanations, the stewards have now asked for a full report to convince them that the car is safe.

A report by the stewards said: "The Stewards, having met with the Team Principal and Technical Representative of Red Bull Racing in relation to the incident involving Car 9 in Practice 1, have requested that the competitor provide to the FIA Technical Delegate a report verifying that the integrity of the suspension is such that the car should not be deemed 'of dangerous constructions' under Art 2.3 of the 2008 Formula One Technical Regulations."

Article 2.3 of the technical regulations says that the "stewards of the meeting may exclude a vehicle whose construction is deemed to be dangerous."

Horner said after the first meeting with the FIA that he was sure there were no safety issues with the design of the RB4.

"It was a front right track rod, that failed," he said. "It was a brand new component fitted after Melbourne.

"We have done over 10,000 kilometres of testing with identical components. You can see that the adhesives failed and it just looked like a human error. So we have absolutely no concerns about the car's safety for tomorrow."

Newey added: "We had a track rod end failure, which caused the accident with David earlier. We know what the problems is and are confident we will be okay for the rest of the weekend.

"If a car hits something that hard then bits are going to fail. If that was another car running over the back of one that is what you want it to do, so it doesn't launch itself.

"The problem itself is what we know as infant mortality, where a cold-bond adhesive hadn't been prepared properly so a very new part failed almost straight away.

"By fitting higher mileage parts we have had no problem through winter testing or anything like that, so we are confident with a higher mileage part we will be fine. "
