NWA: this is insanity. why is it if the pilot is dead, the crash is his fault?
The pilots (may they rest in peace) may have made a mistake based on their training. The operative word here is still "may".
Both Airbus and Boeing before the accident have been concerned enough with AA´s pilot training for upset recovery that they issued a warning against possible tailfin damage due to excessive rudder deflection (please note that Boeing joined in this).
NWA: It was a piece of crap airbus plane, and NOT the pilots falut.
Please tell the NTSB and the FAA. They´re still investigating and seem to be oblivious of your insight.
Seriously, though: As far as I know, the plane had been in severe turbulence before where normal operating limits had been exceeded; As far as I know, Airbus recommends extended (among them ultrasonic) checks in such a case. Did AA perform those? Not as far as I´ve heard.
Even if a manufacturing defect should have been the cause of the accident, AA would probably be wise to reconsider a few issues...
NWA: That tail should never fall off unless a manuver like a straight down dive was to occur, and I doubt that a pilot would push the yoke fully foward in turbulance.
Please excuse my ignorance, but what does a dive have to do with the tailfin coming off?? It´s lateral forces the tailfin is most vulnerable to.
