CCTV of the A350 hitting the CRJ

[Patrick AL]

Ouch!

...must say.... I am very surprised to see the tailplane -particularly of a T-Tail --'snap off' quite so easily and cleanly-?

I would've thought there would be a substantial vertical structural spar through the rudder and into the airframe around the APU?

-maybe it's there, and it just snapped, rather than get deformed/bent?

Wonder what the structural certification testing protocol is for anticipated tailplane lateral loads - in "G's".

[JCA]

There was another video circulating with the ATC conversations. The pilot acknowledged that he had hit something and asked if someone could tell him what it was. Situational Awareness failure perhaps? I mean the only thing he could of hit would have been the CRJ. Yes? No?

The pilots of both aircraft are to blame in my view. Why was the CRJ stopped too close to the taxiway used by the A350? And, as JCA hinted already, why did the A350 pilots not check for clearance? It's not as if that red and blue tail could possibly blend in with the background!

Also puzzled why cameras are not installed in large airliners to feed airframe/surroundings live images to cockpit? --it's done in every second car nowadays, so it's not about the tech not being available.

Usually the tail has 6 bolts holding the v stab to a fitting on the fuselage. I'll try and find a photo and post it here.

I believe that there are a number of attachment points rather than any sort of spar running through? In that case the fixed point of resisance is at the fuselage and you gain leverage the higer you push it. Levers - powerful ancient tech

"...er, we just hit something on the taxiway: can you tell us what it was?"

As if they didn't know or couldn't work it out!!
