This month we move beyond the academic and nebulous notion of  Human Factors  and face head-on some hard realities about how we, pilots and mechanics, are The Human Factor that stands in the way of heightened performance and the related reduction of accidents.    Based on published data involving decades of study, we will make the bold claim that the majority of general aviation accidents are not "accidental" at all.  In fact, it will be argued, both the number and classification of future occurrences can be predicted with a high degree of accuracy, so how can they be called accidental?     We ve known what to do for years, but we are only now at a point where we can be smart enough to do something about it.  We have previously been so distracted by the apparent easier gains of fixing system reliability issues and creating (and then blaming) new technologies, that we missed the big opportunity our complex human selves.    It is time to change, and we can do so by instilling safety cultures at every level of GA operations.
