But there is. However, the pilots on the flight deck in this particular plane were almost all "newbies". Not new to flying, but new to this aircraft. The auto systems from Boeing planes to Airbus planes differs substantially. One of the pilots who was in the cockpit, I wont say flying because clearly none of them were, was new to the Boeing jet and was coming from years in an Airbus plane.
The guy in the right seat was deep in the 777. He was making his first trip as an instructor in an effort to get the guy in the left seat qualified in the 777. Left seat had only 43 hours in 777, but Right seat had a whole bunch. If (when I think) pilot error is named the primary cause, right seat will be ultimately responsible.
If the NTSB does its job thoroughly, it will also blame the system that allowed such an unfortunate pairing to occurr. Not sure what the jump seat guy was doing, but simple pilot error usually isn't so simple. I wonder how many Asiana flights have come close to a similar outcome but did not report it to their safety folks. Chances are high that a lot of "free lessons" went undetected.
