A bit breezy in Michigan

[Stinky]

Very windy in West Michigan when this happened. Canadian ferry flight.

There's a video floating around taken by the backseater showing severe aileron flutter on the right side. The fact they made it to the ground alive is impressive in itself.

Did you also see the tach. reading 2500 RPM in that video. Pilot needs to pick up a copy of "From the ground up" and study Maneuvering Speed.

While admittedly I don’t have a doghouse plot for this aircraft.. something tells me that the installed drag prevents maneuvering speed from being a consideration in level flight.

Even a Cessna 172 just barely goes over its maneuvering speed at 2500 RPM.

And as maneuvering speed only means the wing will stall before it breaks at high angles of attack, I fail to see the relevance. The wing here is going to break because of flutter (one reason why we have a Vne) but now that speed is much lower.

From what I understand, flutter is a type of resonance based on the speed of the aircraft. Since all bets are off in an abnormal situation like this.. who’s to say what the correct way to fly is? Maybe they tried to slow down and it made it worse?

A high lift coefficient from a slower speed is also likely to deflect the aileron more and a slower speed is also going to make the aircraft less controllable.
