Visual Flight Rules aren't a local procedure.

As to “pass behind” , the standard wake turbulence separation criteria would not be met , especially passing behind/below and I would not even try that at 200ft under a large jet..
I agree. The prudent thing to do would be to not call traffic in sight and let the controller give you a hold. But first you'd have to know the plane is there.

If that was/is happening, that's a huge problem. But I don't understand how the FAA would be responsible. Visual separation is initiated by the pilot, when they say "traffic in sight." Controllers sometimes prompt it (e.g. "Do you have that traffic in sight?"), but that didn't happen in this case. A pilot should never call traffic in sight unless they truly have it in sight and are completely confident that they can maintain safe separation. I do get the impression that the Blackhawk pilots may not have fully understood that. Both from the NTSB hearings and the ATC recordings (the way they don't even wait for the controller to finish speaking before shouting "traffic in sight request visual separation!")
