Ahh, Wikipedia articles. One minor step up from UTTER AND COMPLETE BULLSHIT.
Try reading the accident reports on both of your chosen examples - they differ wildly from the Wikipedia articles conclusions.
In the case of AF296, the aircraft performed exactly as it should have - if the aircraft had allowed the commanded elevator action, the aircraft would have stalled and come down before the tree line. The issue with AF296 is that the pilot was being a fucking twat, had descended to below the height of local obstacles, and dropped the engines back to idle - the engines responded to the commanded thrust increase within the engine manufacturers specs, which is to say that it takes several seconds to spool up from idle to the setting the pilot input. By which time the aircraft was in the trees.
The pilot should not have been flying at that altitude with the engines at idle, they should have been at a high thrust level and he should have been controlling his speed using spoilers, flaps and other aerodynamic devices - if he had done that, he would have had instant power available when he needed it. The bloke was a twat.
If the same manoeuvre had been attempted in a Boeing 737, with the same vectors and the same thrust inputs, the aircraft would still be in the trees.
The theory that Airbus messed with the FDR and CVR is also rubbish, and has been proven in the past to be rubbish - there was a period of "missing data", but that was caused by the tape being folded over, and when folded back again to how it was the data all matches up. A lot of the rumours about data tampering came about from a grainy photo taken of the crash scene, which showed the FDR with a completely different stripe on it than there was in the official photo of the recovered FDR - hence it not being the same FDR. But the original negatives of this photo have never been released for confirmation, and other photos of the same scene show the correct stripe on the FDR.
Remember that the pilot involved in AF296 spent time in prison and has lost every court case he brought against Air France, Airbus, the French aviation regulatory body and everyone else - he is also the main proponent of tampering theories etc by Airbus.
Take it from me - don't assume that Wikipedia articles are unbiased and fair. If you follow the aviation articles long enough, you see some very "interesting" edits and roll backs going on - entire sections backed up by aviation regulatory board citations go "missing", and negative hearsay gets put in its place. These edits only really seem to affect the Airbus pages...
