The accidents that keep getting discussed are generally due to poor piloting.
That all depends in which part of our world you crash in. The Western attitude is to ask why the pilots did what they did. That is because we believe that only when you understand why can you prevent reoccurrence. As you move further east, the blame and punishment stick comes out of the box. It does simplify investigations because the guilty parties were in the flight deck. That saves a lot of work looking for causes. Also, we don't want to start blaming others like the training department, the management, the oversight authorities or the shareholders; especially if they are the same person or related. That would mess up an otherwise very tidy investigation.
