Even if the aircraft was operating with the TAC unservicable the remaining live engine has ample power to arrest the sink rate even on an imbalanced aircraft. The triple has a huge surplus of power at typical landing weights, and I have messed up enough single engine go-arounds in training to know there's enough power available in a twin jet on a single engine.
