I would agree that we have a "cowboy" pilot problem in AK, and also that at least liability insurance should be mandatory on airplanes. It's really not that expensive, about the same as for a car for many small 2-4 seat aircraft. 

That being said, as long as humans are flying planes, mistakes will be made, they will crash, and people will die. It's not a problem that can ever be "fixed". All the training and skill in the world cannot make a pilot a robot!

While most GA accidents are pilot-caused, to automatically jump to that conclusion and criticize the pilot before facts come out is flat out wrong.
