And the data/reports, both private and public, reflect that. Hence no AD. The facts speak whether you agree or disagree with them. However, retrofitting with crash-resistant tanks will cure only a part of the issue. The US military learned decades ago that pressure-type fuel systems are a major cause of post accident fires. That is the reason most military and transport cat rotorcraft have suction type fuel delivery systems. While its tragic to read through the Astar reports, when you lay out all these types of incidents from the past 15 years you might be surprised at the causes, results, and number. Especially when compared to the GA avgas side.
