A method of stopping an overspeeding engine () of a rotorcraft (). A protection device stops the overspeeding engine () on condition of a comparison between a mechanical power requirement () of the rotorcraft () and a predefined power threshold (). Stopping of the overspeeding engine () is authorized by the protection device () on condition that said mechanical power requirement () is identified as being less than or equal to the predefined power threshold (). The mechanical power requirement () of the rotorcraft () is calculated on the basis of at least one current or anticipated value for the opposing torque () of a main rotor () of the rotorcraft.
