Well, that's one way to look at it.
Another way would be to say the training captain was not adequately monitoring the FO. Or that the FO wasn't properly prepared to be flying in those conditions, even with a training captain.
The accident report doesn't say anything about the training captain's fitness for flight. I've heard he had complained of being sick prior to departing on this flight. Obviously I wasn't there, so at this point I'm just spreading rumors.
But given the inexperienced new hire and the low weather conditions, I think we'd all agree the training captain needed to be on his A-game. If he wasn't, how much pressure would be on him to complete the flight? That's the sort of corporate culture I'm concerned about.
I'm not trying to sling mud. I'm just saying, the NTSB reports don't always analyze the subtle pressures pilots face out on the line leading up to an accident.
