McLaren have been fined by stewards at Monza for running a new lightweight gearbox that had not been crash tested in last month’s Hungarian Grand Prix.

McLaren did not feel the modifications were sufficient to warrant a new crash test and hence only notified the FIA of changes on the Thursday of the Hungaroring meeting. Exact details of the gearbox revisions were supplied after the event and the structure was subsequently tested successfully.

However, while stewards accepted that McLaren’s cars had been legal at all times, they felt that the changes had been significant and that the team could - and should - have notified the FIA far earlier, in time for the new gearbox to be crash tested prior to the race.

“By delaying the supply of information to the FIA (which could have been supplied on completion of the modification to the gearboxes during the week commencing Monday 16th July), McLaren deprived the FIA of the opportunity to consider the changes made and require impact testing to be carried out before use,” said the stewards.

“Had such information been imparted in due time the tests could have been satisfactorily completed prior to the Hungarian Grand Prix such that their use would have been without criticism.”

The stewards thus found McLaren to have broken Article 16.1.2 of the technical regulations, which states that "any significant modification introduced into any of the structures tested shall require that part to pass a further test."

This, combined with McLaren’s failure to disclose the changes in time to allow for a new test, prompted the stewards to fine the team US$50,000.
