PJ2,
You state "As mentioned above, the accident rate has somewhat stabilized and is proving difficult to reduce."
Very true!
Tony Kern's premise in his book 'Flight Discipline' is that although we know the right thing to do (CRM, Human Factors, SOPs, Training, etc) we often lack the discipline to carry it out. On the jacket cover he states that "A skilled pilot without flight discipline is a walking time bomb."
Personal experience tells me that one of the most difficult tasks an aviator faces is to be consistently disciplined. Failure in this tremendously important area has in too many circumstances caused loss of life and property.
best regards,
