If you trace the causal chain back far enough, what lead to her crash was the government's inept response to the Colgan Air crash, in which the 1,500 rule was created. Because pilots now need 1,500 hours in order to be hired as a commercial airline pilot, every person with aspirations to becoming an airline pilot immediately becomes an instructor in order to build up their hours. So flight schools are inundated with "instructors" who have hardly any flying experience, and hardly any experience instructing students in any capacity. Her first instructor was too dumb to be up in the air teaching anyone to fly. Which is why she had the skills of a 40 hour pilot at 400 hours.
