A Turkish A321 airliner was hit by an Asiana A330 on 13 May 2018 at Istanbul Airport. It seems a large amount of fluid was released from the damaged section. What is the fluid? There is no APU up there so only hydraulic fluid, am I right?

It is hydraulic fluid. This works on 3000psi so that would explain the geyser.

I am not familiar with the A320 family but on most aircraft hydraulic system there are usually isolation valves to ensure that part of the system remains serviceable if there is a sudden loss of pressure/fluid in one part of the system.

  • $\begingroup$ I think you are talking about hydraulic fuses and they are normally on the landing gear to retain pressure for the other brakes if a line blows. There wouldn't be anything like that on lines going to the rudder system. $\endgroup$

  • $\begingroup$ is that really 20 MPa, i.e., 200 atm? $\endgroup$

  • $\begingroup$ 3000psi for most aircraft. The A380 works with 5000psi. $\endgroup$
