Its no big deal to replace a couple of pitot/tubes
on an AiRBUS.
Lets say, 4-5 hours, including test.
But like you say, are there spares?
In situations like this, the manufactor is not able,
to follow the demand.
Maybe, they are not even finished, to design the probe.
But they have "talked" to Airbus about it.
I like EASA, but its like a "postoffice",
Things take time.
