Thanks for posting this. I had wondered what the FAA found as the cause.
An Enhanced Vision System (EVS) is something I'll look at for our future corporate aircraft. Why anyone would want to fly without it is beyond me. Too bad it wasn't available for the King Air a few years ago.
Here's a story about the report:

Incompetence on the part of the pilots was the cause of the crash.
