Have a look at this accident report, not much left over of aircraft after a post crash fire but they still got a lot of good data from the Vision 1000 unit:

Not saying the accident investigators will this time but they might, of course FDR / CVR like in the bigger aircraft would be ideal but cost prohibitive, this a a great solution for the smaller helicopters.
