Yes I am saying it’s the same problem.
The FAA said s using the “Dutch Roll” to cover up the problem. What it is the rudder hardover puts the aircraft into a diving roll depending on where the rudder jams.
Problem being the failure of the rudder control hydraulics identified in the 1990s that caused unwanted deflection? If that's true, it's incredible that it hasn't been fixed long long ago. I'd credit that some new malfunction has cropped up that does the same thing, yes I would. Could be a maintenance issue, could be something that can be designed out, but if it's the latter it took an awfully long time to rear its' ugly head. Hundreds of thousands of flights.
It COULD even be pilot error. I've read that single-engine WW2 fighters would dutch roll when carrying a full load of fuel if the pilot wasn't careful to be light on the rudder pedals. Could this airline pilot have made a careless move and is now covering up? All speculation at this point.
