An official FIA document confirms that article 3.5.9 of the FIA Formula One technical regulations had been breached.
“The stewards, having received a report from the technical delegate, summoned and heard from the team representative, having considered the following matter and determined the following:
“The thickness of the plank assembly was below the permitted minimum thickness.
“Car 81 is disqualified from the Rece classification. All other drivers move up in the classification.
“The stewards heard from the team principal, team sporting director and technical director of McLaren Formula One team, the FlA single seater director, the FIA single seater technical director and the FIA technical delegate.
“The rear skids of car 81 were measured and found to be below the minimum thickness of 3mm specified under article 3.5.9 of the technical regulations. The relevant measurements were RHS front 8.88mm, RHS rear 8.93mm. The measuring device was a mitutoyo micrometre purchased in May 2025, and according to the manugacturer’s specifications, accurate to within 0.001mm.
“The rear skids were re-measured in the presence of the stewards and the three McLaren representatives, and those measurements confirmed that the skids did not comply win the regulations. The relevant measurements were even lower than those measured originally by the technical delegate.
“Accordingly, the stewards determine that a breach of the technical regulations have occurred.”
Norris finished second in Las Vegas, two spots ahead of Oscar Piastri in fourth.
Article 3.5.9 e) of the FIA Formula One technical regulations reads: “The thickness of the plank assembly measured normal to the lower surface must be 10mm ± 0.2mm and must be uniform when new.
“A minimum thickness of 9mm will be accepted due to wear, and conformity to this provision will be checked at the peripheries of the designated holes.”
