Twin engine airplanes have a "Minimum Controllable Airspeed" which is typically a bit higher than stall speed.
With one engine out, the other at full throttle, below this speed, full rudder will no longer keep the airplane flying straight.
Without
immediately reducing throttle and shoving the nose down, the asymmetric torque from the operating engine out on the wing will cause the airplane to begin turning towards the dead engine, and begin to roll over on its back.
It happens quicker than reading about it.
Among all the colored markings on an Airspeed Indicator, twin engine airplanes have the Blue Line, marking Minimum controllable Airspeed.
It is imperative when flying a twin to always remain above Blue Line.
