I'm not arguing that the fault is with the moving aircraft and the responsibility rests with the Captain whether he or the copilot was doing the taxiing.
However having taxied widebodied planes where one cannot see the wingtips and having taxied at JFK I do have some sympathy with the Air France pilot.
If one has been assigned a tight parking spot it is common to have wingmen assigned to assist with parking but it does not happen for routine taxiing. At holding points short of the runway where several taxiways merge into a large pan one has to take particular care.
If someone is correctly following an ATC taxiing instruction and is taxiing in the middle of the taxiway and clonks a wingtip it is highly likely the aircraft he has hit should not be there. The taxiways at JFK are not that wide and there is little scope for going right of the centreline to avoid an obstacle on the left. Indeed turning to the right merely makes the left wing stick out a bit more.There will doubtless be questions as to was the regional jet in the correct place and if he was then it may have been an incorrect ATC instruction to use a taxiway that had inadequate wingtip clearance for an A380. If the Air France had realised and come to a stop in time before impact he would have had to be pushed back which is a major cock up on someone's part.
So although the responsibility for the accident is ultimately that of the Air France Captain it is likely that one or more other errors have been made first by others that led to this accident. The outcome of the investigation will be interesting.
