Does the plane stall easily? Why are all the planes in the air crash caused by stall? 09 Air France could not stall for 3 minutes and fell from10000m. It's terrible.

First of all, let me tell you that not all air crashes are caused by stalling. Let me give you an example. CCA 129 is not stall, but CFIT. In addition, as can be seen from the classification of the column of "air crash cause" above ASN official website, I am stuck here:

plane

Body failure, design error, engine, flight surface, instrument, booster, system, landing gear.

ATC& sailing

Language/communication problems, VFR flight in IMC, wrong or misinterpreted instructions.

Cargo accident

Wrong center of gravity, aircraft overload, etc.

collide

Aircraft collisions on the ground and in mid-air, collisions with birds and objects.

external factor

Foreign body damage (FOD), wake vortex.

crew

Alcohol/drug use, mental state, non-compliance with procedures, lack of rest/fatigue, etc.

fire

Hangar/ground fire, fire in flight, etc.

Landing/takeoff

Fast and heavy landing, tail wiping, rudder/aileron/gust locking, wrong take-off configuration (flap/trim), etc.

maintain

Failure to follow AD and SB, incorrect installation of parts, etc.

result

CFIT, crash landing, runaway crash, etc.

safe

Destroy (a bomb), shoot down, hijack, etc.

weather

Ice, lightning, thunderstorm, wind shear, etc.

So the plane crash was not just due to stall. Then you asked if the stall could be saved. It must be. Air France stalled because the pitot tube was blocked and there was a storm. First, the second co-pilot was a little messy, and the second co-pilot Bonan was crazy about pulling the rod. If he didn't pull the lever, the plane wouldn't stall. Even if it stalls, it can theoretically be saved by changing the speed with altitude. Bonan kept pulling the rod and the first co-pilot kept pushing the rod, so the system automatically covered their operation and finally collapsed.
