Ryanair Boeing 737 MAX plunges 2,000ft in 17 seconds

An investigation was launched after a Ryanair Boeing 737 Max experienced a rapid descent of over 2,000ft in just 17 seconds during its approach to London Stansted Airport. The incident occurred on a flight from Klagenfurt, Austria, with no reported injuries to passengers or crew. The UK's Air Accidents Investigation Branch (AAIB) is conducting the investigation, with concerns raised by aviation analysts given the ongoing issues surrounding the 737 Max model. The aircraft landed safely after a go-around procedure, with the cause of the incident still under investigation. Flight data analysis revealed a significant deviation from standard approach parameters, highlighting the critical importance of maintaining stability during the landing phase. This incident was one of only six airline incidents in the UK last year that warranted a full AAIB investigation, emphasizing its severity within the aviation industry. Boeing, London Stansted Airport, and the UK's Civil Aviation Authority have refrained from commenting on the ongoing investigation.

Why make a story about this six months after it happened but before the cause has been identified?

But the incident of this post here really sounds concerning, according to The Aviation Herald [0]:

> The aircraft accelerated and climbed through about 4000 feet at 197 knots over ground when the aircraft began to rapidly descend to 2175 feet MSL (1825 feet AGL) within 17 seconds accelerating to 280 knots over ground, climbed and descended a second time reaching a minimum height of about 1700 feet AGL. The aircraft subsequently climbed to and stabilized at 3000 feet, positioned for another approach and landed without further incident about 12 minutes after the initiation of the go around.

> The British AAIB reported they have opened an investigation stating: "High speed and high nose down pitch attitude during go-around, London Stansted."

It seems interesting that they aren't coming out with any clear indicator that it was an issue with the plane itself? If there was some faulty sensor/software override that caused the nose dive, it feels like they would've mentioned that was a suspect.

7000 fpm is not all that unusual during a descent. What’s unusual here is the proximity to the ground. Nothing in this story indicates there is necessarily anything wrong with the aircraft, and I think more likely this is pilot error.

I’m as much of a 737 MAX critic as anyone, but nothing indicates the aircraft is the cause as of now.

That's ~ 35 meters per second!

At some point there has to be acknowledgement that the design envelope is unsound.

Newly fitted engines have moved the center of thrust far away off the center of mass. This creates huge torque; especially as is it often done in emergency situations: stalling avoidance advises to push thrust to the maximum. If you've practiced a bit with plane simulators (the ones where you design your planes), you know these things are uncontrollable.

And us software engineers should know better: software-patching design errors sometimes just doesn't work. You can't just "polish it". Without active control you can't do it (which by law is reserved for the military casualty risk tradeoff)

MCAS-patching it yet another time isn't the answer.

Why are 737 MAX still flying?

I'm tired of flying. It's a miserable experience to begin with, and getting worse, and now all this junk is happening. Next year my wife and I are planning to try out a train trip to NYC, from Minnesota. It will take quite a bit longer, but I hope it will be a more pleasant trip.

'plunges', 'alarming speed', 'The shocking incident' but in the end 'none of the passengers or crew aboard the 197-seat aircraft were harmed'

Once again we have a non-story overflowing with hyperbole. These types of articles increase unreasonable fear and do an injustice to journalism. I am flat out done with bad journalism that gets its viewership by hyping fear. 'The Standard' is off my list of credible news outlets.

Something I don't understand, Boeing 737 have been flying for years without no issue.

Why since a few month are they a lot of problem with them ? Why did these problems not appear before ?
