Boeing Airmax has another problem: Dutch roll at 32k feet.

Boeing passenger jet has been grounded after experiencing a rare "Dutch roll" while in flight from Phoenix to Oakland.
While at 32,000 feet, the year-old Southwest Airlines 737 Max 8 experienced the issue, which involves "tail-wagging" and the aircraft rocking side-to-side, the Aviation Herald

I got to say; I don’t want to fly on these things anymore.

I remember when the 737 rudder actuators were rolling aircraft over.

Better than a Dutch Oven at 32K feet

Where did you pull up my Microsoft Flight Simulator clips?

You know that crew caught some hands and some cabin shite got fricked up on that flight.

Swiss Roll > Dutch Roll

Looks almost like a fighter with thrust vectoring showing off.

Well, lets be fair here. What does passenger safety matter when compared to our egalitarian principles? people die every day. The important thing is that we be on the right side of history and keep Shanerquita in charge of that quality control project.
FORWARD, bitches !

Discrepancy: Aircraft encounters Dutch Roll at 32,000 ft.
Boeing corrective action: Don’t fly at 32,000 ft.
Boeing corrective action: Don’t fly at 32,000 ft.

Most likely a power control unit (PCU) failure. There is a second PCU built in for redundancy.
It is a relatively easy problem to trouble shoot as the rudder pedals will accurately reflect the deflection in the rudder, that’s your indication of the cause.
You do want to get out of it though as you have one wing creating more lift than the other and going back and forth. So you kind of let go for a couple rounds get the timing down and then make small corrections to come out of the Dutch roll.

Crazy that this occurred on May 25 as well. I get it that some planes will have issues, abort takeoff/change planes or even have minor midair issues. Crazy that it took this long to come out without people mentioning it.
I posted on the Travel Board recently about my recent experience with the MAX 8. It's not a bad plane. It felt a bit smoother/quieter and slightly more comfortable than the older 737s. This plane also has a redundancy for the PCU and it looks like the pilots did what they were supposed to to correct the action.
If this happens on another plane it probably doesn't get near the attention that a Boeing will. I still feel fine traveling on the Max 8. Done a few already. I'd still prefer the 737-800, but we all have to remember that we're flying these in the United States, not in Africa/SE Asia.

The second PCU was also damaged, sign of too much rudder input. Rudder correction is not what you want to do in a Dutch roll. Small aileron inputs is how you stop it.
The pilots may not have recognized they were in a Dutch roll and gave rudder input to make it worse, damage the second PCU and exert structural damage on the plane. The structural damage is the reason this is an incident at all.
The crew did safely land the plane with no injuries so kudos to them.

Well things are gonna get worse b/c now it’s possible they have fake titanium in them. This may extend to Airbus as well.
quote:.
The use of potentially fake titanium, which has not been previously reported, threatens to extend the industry’s problems beyond Boeing to Airbus, its European competitor. The planes that included components made with the material were built between 2019 and 2023, among them some Boeing 737 Max and 787 Dreamliner airliners as well as Airbus A220 jets, according to three people familiar with the matter who spoke on the condition of anonymity because they were not authorized to speak publicly. It is not clear how many of those planes are in service or which airlines own them.
Spirit is trying to determine where the titanium came from, whether it meets proper standards despite its phony documentation, and whether the parts made from the material are structurally sound enough to hold up through the projected life spans of the jets, company officials said. Spirit said it was trying to determine the most efficient way to remove and replace the affected parts if that ended up being necessary
