As the dust settles on the tragic IndyCar finale at Las Vegas Motor Speedway, motorsport's governing body, the FIA, has revealed that it is to play a part in determining what went wrong on lap eleven of the championship showdown.

While the basic components of the 15-car accident would appear clear to both those who were at the desert oval and those watching online and on television, the IndyCar Series has already confirmed that it will hold a full investigation in to the pile-up which killed 33-year old British driver Dan Wheldon. Now, that enquiry is to be assisted by the FIA, as well as another US organisation, the Automobile Competition Committee of the United States (ACCUS).

Much has been made about the suitability of the venue - which had not held an IndyCar event for eleven years, and even dropped off the Champ Car radar before the series folded - the number of cars on the 1.5-mile track, at 34 more even than the Indianapolis 500, and the relative inexperience of some of those in the field. IndyCar, however, hopes to be able to release early findings shortly.

"We hope to have preliminary findings to report within the next several weeks," an official series statement confirmed, "In the meantime, it would be inappropriate to comment further until the investigative team has had the opportunity to conclude its work."

Las Vegas Speedway president Chris Powell, and IndyCar veteran Paul Tracy have both attempted to play down suggestions that the circuit was to blame for the accident [see story here], but the accident has raised questions about the wisdom of open-wheel cars racing on ovals at all, as well as prompting calls for a full review to be carried out into safety measures at all such circuits, particularly with regard to the use of catch fencing, after this was thought to have contributed to the severity of Wheldon's accident.
