Flydubai crash: Yoke push 'simultaneous' with stabiliser shift
Russian investigators have disclosed that a nose-down shift in the horizontal stabiliser on the ill-fated Flydubai Boeing 737-800 occurred as a push input was recorded on the crew control yoke. (www.flightglobal.com) Mehr...Sort type: [Top] [Newest]
In retrospect, after a missed approach and two hours of holding because of bad weather without improvement, an alternate airport might have been a good idea.
I am not a pilot...but...I did stay at a Holiday Inn Express....so...my question is...isn't that what is supposed to happen?...I push the yoke forward...the elevator deflects downward and the aircraft pitches down....
i believe the stabilizer is fixed and should not move however the elevator which is attached to the stabilizer is what controls up and down pitch therefore it sounds to me that when the elevator was moving the stabilizer broke loose and moved with it. I do not know much about aircraft so i could be wrong!
The stabilizer is movable and the entire surface moves as one. There is no elevator like in a Cessna 172. Trim is adjusted between the yoke and the stabilizer.
Ya, I saw that too, a 'stabilizer shift' .... meaning what ?
Also, I cannot seem to fathom why anyone was inputting down elevator at this point :
"The jet had been climbing away with its engines at take-off setting after aborting its second approach to runway 22, at a height of 220m."
Everything seems normal for a climb out to whatever the assigned pattern altitude was , and I can pretty much guarantee it aint 220m....... Did the AC stall , or did they THINK it was stalling ?!

i have seen something like this, years ago from a CF18 that crashed following a go-around IMC in YYG.
The conclusion was spatial disorientation from sudden acceleration . It has to do with inner ears , when you accelarete very fast , you have the impression that you are climbing like crazy, thus a tendency to push on the nose which makes you go faster and feeling a "steeper climb" thus pushing some more. Just speculating, but a fairly light jet in a go-around IMC at night when crews are tired ...
