The team confirmed on Tuesday that Mark Webber's rear wing failure, which forced their withdrawal from the Spanish Grand Prix, was down to a one-off flaw. But it was only the latest in a string of failures at the Barcelona track.

The rear wing tore off Kimi Raikkonen's McLaren during the race, and testing has seen one high-speed accident after another over the last few years at what is one of the sport's main testing venues.

Now Minardi technical director Gabriele Tredozi and his deputy John Davis are to raise the issue at the next meeting of the FIA's Technical Working Group, the highest level of technical expertise within Formula One™ racing's governing body.

Various technical team sources in the pit lane believe the wing failures are connected to the design of circuit kerbing at the Circuit de Catalunya because they create freak vibration frequencies that can shatter kevlar wing parts usually strong enough to withstand gunfire.

There are other circuits in the championship like the Brazilian race a month ago where the track is far rougher but where there are very rarely wing problems.

The changes that will be discussed by the sport's leading technical figures would not necessarily be that expensive as they would only involve changing some sections of kerbing on high-speed parts of the track.

Minardi has spent the last three days re-designing and modifying their rear wing as a precaution after Mark Webber's snapped in the warm-up hours before the Spanish Grand Prix.

Team mate Alex Yoong's accident the day before was put down to a collision with a kerb but Webber's front wing break in Friday practice has already led to the front wings being strengthened too.

The team withdrew from the fifth round of the world championship after Webber's Sunday morning accident because they did not have time before the race to discover the reason for the failure.

The changes will be completed in time to contest the Austrian Grand Prix and if the work goes according to schedule the team may test their re-enforced components at a circuit in Italy on Thursday.
