So, on top of:
-takeoff and landing performance and airplane systems
-difficulty in completing normal procedures
-unsatisfactory performance in CRM, threat and error management, nonprecision approaches, steep turns, and judgment
-nervous, had “very low” situational awareness, overcontrolled the airplane, did not work well with the other
pilot, omitted an emergency checklist during an abnormal event, and exceeded a flap speed
-not thinking ahead, and, when he realized that he needed to do something, he often did something inappropriate, like push the wrong button
...when the poop hit the fan, he wasn't even competent at attitude instrument flying on the day it mattered most.
All the above were comments from his 767 training. That same section of the report gets even worse (if you can believe it) when they spoke to the instructors at the regionals.
You don't think a pre-employment sim ride would've caught some of this? That guy shouldn't have been any closer to an airplane than at an airshow.
