I've been recently reading a lot about the DoD's response to aviation (and other class A) accidents. I read the original book on the Human Factors Analysis and Classification System (HFACS) by the US Navy creators Doc Wiegmann and Shappell.
Basically, the book contends:
1. Aviation has gotten super safe, but accidents still happen from time to time.
2. When accidents do happen, they are predominantly caused by human factors (~70-80% of the time).
3. It is important for the safety process and future accident prevention to identify specific human factors and the standardized taxonomy that should be used is the HFACS framework.
I completed this research writing a recent blog post: https://goflightmedicine.com/human-factors-analysis/
What do pilot members and investigating officers think about the value of this framework? Useful product or academic dribble?
