Abstract
A fan exit stator assembly of a gas turbine engine may include a radially inward shroud defining a first slot, a radially outward shroud, and a vane. The vane may include a base portion extending through the first slot and a tip portion coupled to the radially outward shroud. The vane may also include a retainer plate disposed radially inward of the radially inward shroud that projects in a circumferential direction from the base portion of the vane. A circumferential plate dimension of the retainer plate in the circumferential direction is greater than a first slot radius in the circumferential direction of the first slot, thus preventing radially outward movement of the vane relative to the radially inward shroud.
