An aircraft flap blow back prevention device includes a first ball-ramp plate, and output coupling engaged therewith, rotatable about an axis. A second ball-ramp plate is disposed adjacent the first plate such that ball-ramp surfaces thereof are opposed, with a ball therebetween, and such that first and second braking surfaces thereof oppose respective first and second stationary braking structures. A spring biasing the first plate toward the second plate spaces apart the first braking surface and first braking structure. An input shaft axially extends through the first and second plates in a lost window arrangement, wherein an absolute value of rotational torque applied to the output coupling, greater than rotational torque applied to the input shaft, causes the ball to urge apart the plates and the braking surfaces thereof to be urged against the respective braking structures to cease rotation of the output coupling. An associated method is also provided.
