Not quite.... the tendency seems to concentrate on a non IR rated pilot taking off into a 200ft cloudbase..... At best design issues according to some could be a contributory factor
How do we know he was non-IR rated, other than just a post here on pprune? Has there been a statement to that affect by FAA and/or NTSB? If that is confirmed, yes that would appear to be the proximate cause. But I haven't seen any confirmation of that.
I have found the mainstream media to almost always make a total mess of anything remotely technical, so unless there is something more substantial than:
from some of the news articles I have been reading, it would appear the pilot was not instrument rated,
I would suggest that the jury is still out as to whether he was instrument rated or not.
