The consenus seems to be serviceable but not airworthy due to failings higher up the food chain. I repeat that someone flew this aircraft into a rock, and that this would not have happened if basic airmanship/navigation et all had been followed.
I'm afraid that unairworthy aircraft have a nasty predilection for self destruction no matter how impeccable is the "basic airmanship/navigation" displayed before they decide to bite without warning. That is why they are a very bad idea. That is why a responsible Airworthiness Authority sees it as its prime function to provide and maintain airworthiness. On the other hand you have the MOD....
