Well, if you believe the Qatari version of the story the QCAA will gradually remove the remainder of the A350's from service and ground them for safety reasons. Then the aircraft likely will rot away in the desert unless some miracle happens.
The miracle likely being Airbus to buy all these planes back on top of paying a hefty compensation.
One needs to remember that QR does not own most of these aircraft, they are leased.
The aircraft could be placed outside of the QCAA jurisdiction with another carrier by the lessor.
So if QR doesn't own some, or all of the aircraft currently grounded, are QR still paying leasing fees ?
If QR aren't paying leasing fees, then why doesn't the owner repossess the aircraft, repair them and offer them to another customer ?
If the aircraft aren't owned by QR, but QR are paying leasing fees on them, then the argument that QR are trying to cut capacity because they've over ordered (which they're not, as they've returned grounded aircraft to operation and leased other aircraft in) or trying extort money from Airbus as some here seem to believe, just doesn't make sense, never did really. Is it really that hard to believe that QR really do think that the aircraft have deficiencies and that accepting the Airbus current solution is only going to continually involve having to repair aircraft, at significant cost, throughout the life of the airframe.
Having said that, yes I agree that QR have gone about this the wrong way, but in fairness, I really don't think Airbus has acted much better. It's like watching kids throw the toys out of the cot, only on a grand scale, though nothing like China and the tantrum it's throwing at the moment.
