Istanbul taxi accident
I would suggest that the A321 will be easier to repair than the A330. Changing the Vertical stab is a fairly easy task (only held on by 6 bolts) - so as long at the fuselage fittings were not over stressed the only thing that will hold up repairs is finding a spare Stab.
Do A321s have vert stab tanks, because there's a lot of white fluid being sprayed up...

Asiana almost got me in Singapore. Taxied in to their bay whilst I was stopped on the lead in right in front of it. Went between me and the aircraft on the next bay. How they missed both of us I have no idea. Ended up at about 30º off the bay alignment, and didn't hit the bridge. Lucky. And total idiots.

The practice of half entering the gate when it is still switched off is a mistake and a violation.
In some places its written in the airport plates.
With that im not blaming turkish at all, i havent any clue of the situation.
But I can blame Asiana for sure.
Unless the turkish moved backwards, which I doubt, the Asiana had to WATCH where they are going.
Period.

No swiss cheese at all. When you taxi you make sure you are clear of ANYTHING at all times.
If I' m taxing into a gate and I want to stop for ANY reason, I do so. And I only advise ATC when I feel it is safe to do so, certainly not my priority with both engines and people/carts/FOD around me. Again, anyone must make sure he' s clear.

The TK A321 was completely in his right to stop before his parking position, if he/she deems it necessary for whatever reason. NOTHING illegal about this. Yes, obviously you inform ATC of this, but in a congested airport like IST, this can take some minutes, and is NOT a priority. That being said, in the Airline I fly for ( major B747 operator), we will not turn onto the gate if no marchaller or lead-in guidance. We do stop short if for example containers are blocking ( not always correctly visible perpendicular of the stand) or groundcrew/ debris in the area obviously.
HOWEVER... The PIC of the Asiana A330, or ANY Taxying aircraft has the legal obligation to stay free of all obstacles at all times, and “ But I was following the yellow taxiline” has absolutely nothing to do with that obligation. Have some Airmanship people! Taxi is a critical phase of flight that requires full attention of all flight crew members on the flightdeck. If necessary, deviate from the taxiline to keep clear of obstacles or better yet, stop.

Anyone else surprised by the complete severing of the A321 fin, while the A330 hasn't (apparently) even lost its winglet. It does make you think about how rudder forces are transmitted to the airframe in flight (and then think about AA587).
The required rudder forces are minuscule compared to the lift forces of the wing. Think of the force needed to shift the attitude of a boat floating in water versus the force needed to lift it out of the water. This directly translates into the different structural strength of the two components.

You must follow the yellow taxi lines and as far as I know there is no rule which necessitates the cockpit crew to check the wingtips during taxiing. Is there?
There is a rule that you do not taxi into stationary a/c. If in doubt there is no doubt. Wing tips knocking off fins is not a slight graze by a few cm's; it is a thumping whack by a meter or 2.

The A330 damage to the front spar on the other hand.......

I simply wonder if the A321's fin-attachment bolts are designed to fail before the rear fuselage is over-stressed - bearing in mind the proximity of the pressure bulkhead. (For example, I think that philosophy does apply in the case of wing-mounted engine pylons.) But the A321 in this accident suffers a lot of sideways movement as the fin is struck.

Who cares what the A321 was doing or not doing. It was the A330 that ran into it not the other way around. And, it was the A330 that had both the capacity and capability to avoid the accident if they were applying airmanship rather than complacency. Having said that, a poster above did detect a strangeness in the video. The A330 seems stationary (yet the camera is moving) then suddenly the A330 is charging along the taxiway like it had released brakes with throttles advanced. A possible configuration issue with this aircraft type?

LOTFW
We need to bring back the old standard operating procedure when taxiing called LOTFW, Look out the Fu#*king Window!
”Clear Right Side” obviously doesn’t mean anything if you don’t look.
Asiana crew should have been able to see that the Turkish was not fully parked and was not fully clear of the yellow taxiway edge line.

Situational awareness !!
taxi clearance or not, you can’t replace mark 1 eyeball. I can’t see how anyone looking out the window could not see the A321 isn’t clear of the taxiway.
After all, even if you have line up clearance you don’t enter an active runway without glancing at the final approach - do you ? Same applies on taxiways
