The situation is radically different:

Asiana Airlines Flight 162 was an Airbus A320-232, manufactured in 2007

Air Canada Flight 624 was an Airbus A320-211 manufactured in 1991

Germanwings Flight 9525 was an Airbus A320-211 manufactured in 1990.

The Asiana and Air Canada incidents were similar, but the aircraft were of different models, one was 7 year old and the other was 24 year old. The German Wings and the Air Canada aircraft were similar models, but both planes were 23-24 year old, and the incidents were completely different.

Compare that to the 737 MAX 8. Two fatal crashes, during the same stage of flight, with identical models, of similar age. 2 out of 350 planes crashed, where the fleet is barely one year old on average.
