Irrespective of the events leading up to the go-around, I wonder why the number 1 engine/transmission went over the maximum allowed combined torque figure.
My understanding is that the FADEC system should have prevented an overtorque; i.e. the advertised idea is that the pilot pulls the collective and the aircraft should look after its own limits for him. If this didn't happen, why not?
It's a great shame if a pilot makes an honest mistake, the aircraft doesn't work as advertised and so the pilot gets shown the door as the result.
