Flarepilot I believe that general ignorance of operating strength limitations is very widespread...this is something that should be covered in primary training...obviously the FO didn't understand that because he was not taught. In fact my belief is that there was a systemic failure...more emphasis needs to be placed on operating strength limitations in general, there are lots of pilots who don't understand the limitations simply because they were never taught...the fact that the FAA approved such a syllabus is appalling and therefore I agree that the FAA should shoulder some of the blame. When Bob Hoover reverses his side slips back and forth he's going very slow he doesn't break the plane because he understands the limits
