When I think of Air France 447, Colgan Air near Buffalo, and Asiana in SFO, there could certainly be discussion about CRM failings, but ultimately if the pilot flying had applied good very basic flying skills, thing would have turned out better. CRM can help, but it should not be considered to make up for basic flying skill deficits.....
When I'm flying right seat to a new pilot, whom I'm mentoring by agreement, I assume that I might have to work within CRM to apply some of my basic flying skills to "fix" something. If I'm right seat to a senior Captain, I sure hope not!
