Ghost: Your post is right on the issue. It is very unfortunate that anyone should loose their life in an aircraft accident, and doubly so if the accident is avoidable, and I don't mean by sitting on the porch and watching.
A quick search of the FAA Registry shows about 230 of these a/c in several marks and models in the U.S. registry alone. It would seem reasonable for the owners/operators to get together and write a decent pilot's manual. Good project for a test pilot school student.
Now about the engineers.....
