Here's an ATC recording of Virgin and Egyptair aircraft clipping wings at JFK.
Generally, what happens next with regard to sorting out responsibility after a low-speed collision that results in damage to commercially-operated aircraft? (I'm talking about a return-to-gate type of collision where passengers are inconvenienced, rather than a serious evacuation-style incident.) There seems to me lots of factors, for instance:
The captains are in charge of their aircraft, but what if ground controllers gave them poor instructions?
When a parked aircraft were damaged by a moving one, the former might seem the innocent party, but what if it were stopped in the wrong place?
It's possible that an airport itself might have listed incorrect information about its taxiways that leads to a collision.
In automobile accidents, its the insurers who would sit down and come to some agreement, but there's not really an equivalent of the airport in such circumstances. And the stakes are quite high - repairs and delays might be very costly to an airline.
I presume there's always some sort of regulatory investigation, but their prime concern I would think is to stop it happening again, which is not the same as agreeing responsibility and liability. The question is: how do insurers decide who ends up paying, for what is almost always a very expensive error?
