Serious UTair Boeing 737 Upset Involved Excessive Pitch And Roll
Russian investigators have detailed a serious loss-of-control incident last month involving a Utair Boeing 737-500 on approach to Moscow Vnukovo. (www.flightglobal.com) Daha Fazlası...Sort type: [Top] [Newest]
They did have to clean a number of seats, I imagine.
Could someone have hacked into and taken over the plane?
The article states the auto pilot disconnected. We don't know why but it does sometimes just happen. Whatever the reason, once it's off, the 737 is a totally manual aircraft, whatever happened after that was likely due to pilot input. Having said that, until we see the data from the flight data recorder (FDR) we don't know if the pitch up was 'commanded' by the pilots or not. There was an issue decades ago alluded to elsewhere of an uncommanded opposite rudder movement in earlier versions of the 737 (having to due with the yaw damper system which is not applicable to the elevators) but I have never heard of a such a thing happening in pitch.
I would say no... That would be an impossibility and if that had happened there would have been more on the FDR!
Something doesn't compute here. This is on final approach?! Let me get the attitude straight in my head: 45 degrees pitch, 96 degrees bank (so it's past knife-edge!), speed under 135 knots, altitude less than 2,000 feet. This aircraft is not recoverable, something must be lost in the translation or I'm grossly misunderstanding this article.
it's incredible that at a 96° bank angle no PAX was hurted by objects falling from the overhead bins or kept on their laps.
