Pilot error or maintenance errors.
How is 'human error' suggesting any different?
the rest is component failure or the guy at the front gets it wrong.

That's a good point; "human" includes the manufacturers as well.
And the blame game sure can get complicated, even when it's something simple.
For example: the closest I've come so far to an in-flight emergency was a smoking (but still transmitting) transponder in a training aircraft.
When you think about how many factors may have caused that...

Was it a manufacturing flaw?
Was maintenance incorrect or lax?
Were pilots to blame, for not switching it on/off/stby/alt when appropriate?
Now I know as a maintenance tech, in that case your first thought would be "Those dumb pilots always forget to put it on standby, let alone make sure it's off before they kill the master"... and you'd probably be right.

But on the other hand, I've seen some poor maintenance practices as a renter, stuff that required a little more attention from me as the PIC : mostly the usual rap- stuff left inside the cowling, etc.
My favorite pre-flight surprise was a pair of needle-nose vise grips left clamped to a Dzus fastener on the cowling...

However, I won't argue with any assertion that it's usually the pilot who's the weak link, and only in part because of the PIC's responsibility to determine airworthiness.
But I still think that it would be better, in the case described in that article, for all concerned to say "we don't know yet" rather than "it's... um... probably human error..."
