Re: 767
They don't get to determine whether the gauge is an issue on their own -- except, perhaps, in a career-limiting, "sorry, I won't fly this thing."
Instead, it's determined in advance by the manufacturer's MMEL and the operator and local agency who figures out the MEL. If something's on that list, then you're good to go as long as you follow whatever rules the list specifies.
Just about all of these incidents and accidents reveal interesting things about the inter-related parts of the system, rather than just a simple "this guy blew it." It's often described in the US as getting all the holes in the Swiss cheese to line up just right so that an accident can occur. (I know that folks elsewhere have different cheese names. :->)
