NTSB Investigating After Boeing 737 Suffers Dangerous 'Dutch Roll' Incident in Midair
Western Journal ^ | June 17, 2024 at 4:27am | Jack Davis

On May 25, Southwest Airlines Flight N8825Q, a Boeing 737 Max experienced what is known as a “Dutch roll” — where the aircraft tail wags back and forth as the wings rock in see-saw fashion, according to NBC.

The Phoenix to Oakland flight had 175 passengers and six members of the crew aboard. The plane was initially reported to be at 38,000 feet at the time of the incident, but a National Transportation Safety Board investigation showed it was at 34,000 feet.

Well it looks like the FAA has a "Cover Name for what happened last month. They call it

"DUTCH ROLL"

MAYDAY TV Shows "Hidden Danger" United Airlines Flight 585, USAir Flight 427, and Eastwind Airlines Flight 517

On 3 March 1991, a Boeing 737 operating as United Airlines Flight 585 suddenly rolls into a dive and crashes within eight seconds, killing all 25 people on board. On 8 September 1994, USAir Flight 427 also rolls and crashes within thirty seconds, killing all 132 people on board. On 9 June 1996, Eastwind Airlines Flight 517 also rolls unexpectedly in similar circumstances, but the crew successfully regains control of the aircraft and lands safely. The cause of all three incidents was a design flaw with the rudder's control system which allowed the rudder to suddenly and unexpectedly go to full deflection and jam due to thermal shock of the hydraulic control valve.

I’m becoming convinced some of this is intentional.

Boeing sabotaged itself with its monumental arrogance and some very poor design choices in the past 30 years.

The reporting is sure targeted for the sensation value. This is particularly glaring since most issues that have been reported are airline maintenance, pilot error or engine issues not related to the airplane's integrity at all. Yet, they always manage to get "Boeing" in the headline. I think it is intentional to hurt Boeing, almost blackmail.

Almost 45% of the US airline fleet is Boeing. Of those, 1,300 of those jets currently flying are 737s.

This is one incident of the thousands of flights per month involving 737s.

Those who "ain't going if it's Boeing" can walk. It is way more dangerous to do that.

Crews have been trained how to deal with it... So competent pilots shouldn’t have a problem. By the sounds of it, the training is obviously working because the pilots in this case avoided a problem during this incident.

Ha! I used to post that until some Krybaby Karen whined about it, whenever I posted it.

I got tired of their whining.

Are we suggesting that a fault identified over 30 years ago hasn’t been fixed? Please.

BTW classical “dutch roll” when I learned aerodynamics didn’t involved the rudder at all. It was a symptom of a mismatch between the wing dihedral and the area of the vertical stabilizer, plus other side areas both ahead of and behind the center of mass. Some designs, notably the Bristol Beaufighter cured dutch roll by raising the tips of the horizontal stabilizer to form a distinct vee.

Dutch rolls are not uncommon, nor are they necessarily dangerous depending upon the severity. The older model Beechcraft “V” tail six-seaters were bad about it, as they had a constant mild dutch roll just flying at level flight. I have a few hours in them, and that constant tail-wagging drove me crazy. I never understood why people would own these planes.

Boeing sabotaged itself by merging with McDonnell-Douglas, adopting their pathetically stupid business approach that emphasized short-term economics over engineering, and most of all by letting one of the most pathetically ignorant of a very large number of pathetically stupid CEOs, Jack the unethical pinhead Welch, run the company. If talent determined wealth most CEOs would be living in trailers.

I get a kick out of reading the reply’s. The basic story was posted a day or two ago with the comments here going the opposite as in this version of the story. It seems the pilot left the cabin before the incident.

The point is that you all better wait until the real facts are in.

This not Pilot Error or Training problem. This is a HARDWARE problem. The PCM is the Slave Cylinder for the Rudder control. The Housing and Piston were/are physically damaged and the Piston and Housing get scratched by Debris in the Hydraulic Fluid and "jam" the Piston resulting in loss of control of the Rudder.

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.

You are thinking of the SWA Flight in Hawaii a few days ago.

Different issues. The prior ones were a defective servo design pushing int the rudder full
