I will not speculate on this accident as well, but with that being said the Caravan is a easy airplane to fly. It is very forgiving airplane and is one of the main reasons the aircraft is used by FedEx. I have flown Caravans with inflight failures such as a failed attitude indicator because I had a second working attitude indicator. FedEx is also replacing the old instruments with glass instruments in order to reduce the instrument failures and improve situational awareness. Hopefully this will cut down on controlled flight into terrain (CFIT). I am truly sorry for your loss and wish you a speedy healing process.
