@safriz Has been doing some investigation on his own as well. Lets see what he says.
Thanks for the tag.
I guess I am late to the party and most of the things have been discussed. Except one.
To go round, the TOGA has to be engaged.
This is a special position or a button on the throttle stick.
If pilot aborts landing after touchdown, engaging TOGA instantly revs up the engine to maximum thrust and adjust flight surfaces to takeoff position.
If TOGA is not engaged, the engines will take time to spool and flight control surfaces will have to be corrected manually for takeoff. That can cause the plane to bounce on the runway.
So I put my money on pilots forgetting to engage TOGA Mode on the throttle, which cause the plane to bounce three times, scraping the engines 3 times and damaging them so badly that they died within minutes of takeoff.
This is an actual picture of A320 throttle. TOGA is the farthest forward position.
The stick moves freely only to the first notch which is about 60% thrust. Then it has to be pushed to second notch and then to the last which is TOGA.
It is very much possible that the pilot only pushed the stick to first or second notch.
This also happens to be a very common error in this type of situation.
