The FIA has contacted Red Bull and Ferrari for more information on their rotating rear wings following two crashes involving Max Verstappen.
The governing body wants to confirm that both teams comply fully with safety rules for the active aerodynamic systems, which first appeared this season.
Ferrari introduced its version during pre-season testing in Bahrain and raced it starting at the Miami Grand Prix. Red Bull developed its own concept since November 2025 and brought it to Miami as well.
Red Bull suffered failures on Verstappen's car at Spielberg and Silverstone. The driver called the situation super dangerous after the Silverstone incident last Sunday.
Red Bull will review the design ahead of next week's race at Spa-Francorchamps. The FIA request does not currently include McLaren, which has also worked on a similar wing.
