A screw-like device found in the wreckage of the Boeing 737 Max that crashed last Sunday in Ethiopia indicates the plane was configured to dive. ==============================================================
A screw-like device found in the wreckage of the Boeing 737 Max that crashed last Sunday in Ethiopia indicates the plane was configured to dive, a piece of evidence that helped convince U.S. regulators to ground the model, a person familiar with the investigation said late Thursday night.
Federal Aviation Administration chief Daniel Elwell on Wednesday cited unspecified evidence found at the crash scene as part of the justification for the agency to reverse course and temporarily halt flights of Boeing's largest selling aircraft. Up until then, American regulators had held off as nation after nation had grounded the plane, Boeing's best-selling jet model.
The piece of evidence was a so-called jackscrew, used to set the trim that raises and lowers the plane's nose, according to the person, who requested anonymity to discuss the inquiry.
A preliminary review of the device and how it was configured at the time of the crash indicated that it was set to push down the nose, according to the person, who wasn't authorized to speak publicly about the investigation.
The jackscrew, combined with a newly obtained satellite flight track of the plane, convinced the FAA that there were similarities to the Oct. 29 crash of the same Max model off the coast of Indonesia. In the earlier accident, a safety feature on the Boeing aircraft was repeatedly trying to put the plane into a dive as a result of a malfunction.
All 157 people aboard Ethiopian Airlines Flight 302 died early Sunday shortly after the plane took off. The pilot reported an unspecified problem and was trying to return to the airport. The plane crashed near Addis Ababa, Ethiopia's capital. The plane's crash-proof recorders have been sent to France to be analyzed.
The discovery of the jackscrew was earlier reported by NBC News. 3 COMMENTS
Separately, the New York Times reported that doomed Ethiopian Airlines plane was in trouble almost immediately after takeoff as it lurched up and down by hundreds of feet at a time. The captain of the Boeing Co. 737 Max 8 asked in a panicky voice to turn back only three minutes into the flight as the plane accelerated to abnormal speeds, the newspaper reported, citing a person who reviewed the jet's air traffic communications.
Of course it is.
And these systems are run by tremendously complex software, and bugs -- serious ones -- are inevitable.
Proper security addresses the first concern, and proper QA addresses the second. But you can't guarantee hack-free or bug-free. You can only make failures less likely.
There is a video of a passenger jet doing exactly that....had a jammed trim tab ...was flown upside down while pilot on the phone to factory maintenance.....but and eventually crashed.
There are billions at stake. I expect the NTSB/FAA will try to come up with an accelerated conclusion.
So you think 9/11, including Flight 93, was legit?
How many hours do you have .... light civil + heavy metal ......??????
Around 30,000 hrs. 8 years jets and tankers USMC . 30 years major US carrier now retired.
About 30,000 hours. 8 years USMC in jets and tankers and 30 years airline, 24 years left seat. Flew 727, 737 and MD80.
You just summed up the problem with the Establishment mindset, regardless of the establishment. The incompetent are slaves to the system, unfit to fly their own (be free).
Thanks for that gem.
I agree. I had not read too much into this accident before commenting. But I have followed previous accidents. Sully commented a couple of days ago about the co-pilot having 200 hours, and how this is RIDICULOUS for any airline, even a 3rd World S_ithole airline, and I agree.
The fact is I don't know what caused this tragedy.
Wow - a person on the forum that actually knows something about aviation.
Well, you missed a class or two (BTW Trumped you, 747-400 world -wide air cargo.. that’s heavy metal boyo,Go Navy ) LOL
I have no idea where you are coming from or where you are going but make sure your parents know.
From all I’ve read and heard, sounds like a bad computer program.
If so, Boeing will be on the hook for billions.....................
Is Boeing to big to fail???
Here’s 777 pilot Juan Browne’s March 15th evaluation of the stabilizer jack screw’s position on the Ethiopian 737-8 Max
Juan has a new video out. It is 25 minutes long. You can skip the first 5:30. He just gives background on flying various military and commercial aircraft. He is currently rated on the 777 and has flown the 737-800, but not the 737-Max.

I watched Juan’s 3/20 update video today. Those 737 Max accidents didn’t have to happen.
