Abstract
A device and method for determining whether a no-back device is functioning properly includes a no-back device coupling an input shaft and an output shaft. A no-back output gear is coupled to the output shaft, and a reaction gear is operably coupled to the no-back output gear. A check device includes a rotatable drive feature having a first end accessible for rotation and a second end engaged with the reaction gear. The functionality of the no-back device is evaluated by applying a rotational torque to the drive feature.
