Isn't there a stipulation in the rules that all SLM mechanisms must fail closed?
Yes and you can do that with springs inside the mechanism (think like air brakes on a truck need air pressure to unstick the brakes). So that would try and push the wing closed when there's no actuator power, but if the mechanism itself binds because of flexing or other issue that only shows up on the track, then it doesn't really matter, it's not going to work.
With every design, there is what you want it to do, what it does in the factory when you show it to the FIA, and then what it does on the track...
As explained in the video linked a few posts before, the issue may be on the fluid dynamic side and not on the mechanical closing of the wing. In substance, there may be situations in which the flow does not reattach and at that point there is nothing you can do.
They might also have reattachment issues that could show up on another day, but so far there is a much simpler explanation which has been provided.
Verstappen told Sky Sports F1 that the cause of his Silverstone spin was identical to the issue that put him in the barriers in qualifying for the Austrian Grand Prix a week earlier.
“The same as Austria, the rear wing just doesn’t fully close,” he said. “I saw the analysis. It looks like it closes, but it doesn’t. It closes but it’s just a little bit open and you lose a lot of rear downforce. And that’s why the car just spins off the track.”
