Quote: Is a Mid Air Collision consistent with what (little) we know so far? Somehow seems to be about the only possible scenario not yet discussed. What is big enough to detach part of A321, can climb to 10 km and at the same time doesn't leave any recognizable parts on the ground after such collision? Just trying to get a handle on the airline saying "external influence" as a cause, and the range of what that might mean. |

Due to numerous requests of journalists and industry experts we provide technical documentation and documentation of audit Flight 7K-9268. This official documentation, talking about the technical side of serviceability has also been transferred at the request of the Investigative Committee. (с) Metrojet |
I had been a bit confused about reports of bodies found well apart from the main wreckage as "missing limbs"....but I believe that may be a poor translation of "dislocated limbs"....but my Russian language skills are no longer good enough to read original reports and say for sure.
But dislocated limbs are indeed consistent with ejection into high speed air stream as with the mid-air break up that is now fairly certain. RIP all. |

Once again, apologies for my non-professional perspective.
There seems to be an emerging trend (omitting for the moment the foul play options) in the analysis presented by knowledgeable commentators here which would tend to suggest that the locus of failure was somewhere at the rear of the aircraft, adjacent to the pressure bulkhead and stabilisers. At the same time several photographs have been posted of this aircraft exhibiting very conspicuous hydraulic fluid leakage in the same area, extending - or so it looks to me - to a seam encircling the fuselage. Now back in the day when I operated and maintained heavy earth-moving and mining plant I'd have regarded a hydraulic leak like this as warranting a repair asap - on a bulldozer, much less an aircraft. Having read most of the posts, including some which have been moderated away, there doesn't appear to be any informed comment suggesting that there may be a correlation between this manifestation and the accident. Which seems pretty surprising to an observer. |

Stabiliser trim, servo and pulley system? Am I missing something?
|
CNN have a picture of the tail section. Not sure how long it'll stay up.
Breaking News, U.S., World, Weather, Entertainment & Video News - CNN.com I don't have time to grab it and post it. If someone can get there and grab the pic then post it...? |
Quote: Is a Mid Air Collision consistent with what (little) we know so far? In short, no. Probably that's why it's not discussed. (There would be clear signs, not to mention two sets of smoking wreckage) And - just to be clear, about other posts - I'm not speculating about anything (especially not "US drones".....). Just asking a question that I had not so far seen posed, in the light of what has so far been seen, and said.. |
What is known about the passengers onboard? Someone travelling incognito?
Possible targets? Russian mafia? Weirder theories have emerged. |
Large rear chunk
I came across this photo, might fill in the missing "extreme end" question posed.

That pic of the tail is the same one we've seen many times I believe. VS and empennage.
HS still AWOL.... |

For what it's worth, to the original poster at 482, The stab trim is hydraulically operated normally. Electrical backup IIRC. |
@Kulverstukas
From the docs you post ( http://urgent.metrojet.ru/files/tehd...1102175048.zip ) it seems that in 3-2014 a C-check was performed, not the much more thorough D-check, as was stated here before. |
damage ??
the VS damage we see is due to ground impact For a crude comparison - take a pop can- hold it horizontal- push up with your thumbs from the bottom in the center, pulling down on both ends. The lower part fails in compression. Of course the upper part is in tension ( if you scribed it around the top half- it might actually tear the upper half ) Now compare to the aft section photos with part of the vertical stab .. It takes a lot of force to tear the aft section at the production join - for example a major dive and pull up - or a failure of control surfaces at high speed allowing rudder/elevator to ' flop " |
Isn't the rudder also AWOL?
|
Smott999
No it's not. That's the tail cone. APU is behind the rear ..... |
"I came across this photo, might fill in the missing "extreme end" question posed. "
That appears to be the area just fore of the APU and tailcone. Isn't that a fire bottle attached in the middle? |
Staining
I don't know what you call the grey area where the HS attaches, but the picture of it in the desert has little or no staining of the paint around it, while in the picture taken earlier this year shows the same area to be heavily stained.
