Haas have been fined a total of $6,500 (£5,051) after a wheel from Esteban Gutierrez’s car came off during the Malaysian Grand Prix.
The Mexican driver was deemed to have been released unsafely from the pits after his third pit stop, before a mechanical failure caused the wheel to become detached from Gutierrez’s car.
Haas has also been told to file a report to Jo Bauer, FIA technical delegate, in order to explain the failure and proof of “all corrective actions” taken, in accordance with a stewards report.
“Having reviewed the audio from the car, the available data and spoken to the driver and team concerned, the stewards were satisfied that the driver Gutierrez did not know that he was driving the car in an unsafe condition. It appears a mechanical failure led to the wheel being able to be tightly fitted to the car while not actually attached correctly,” the stewards report said.
“An additional failure occurred in Turn 1 under braking, but the wheel was still retained in an abnormal way until it appears that the failure of the rim blew the wheel past the retention devices. Having spoken with the technical delegate, the stewards were satisfied that the retention devices operated within their required design limits,” it continued.
“However, as some function of the design, part failure of fitting allowed the wheel to come loose on the track, which is considered a serious safety issue, the stewards determined that this led to the car being released in an unsafe condition.”
Gutierrez was not punished for this incident.
