<p>A method for repairing or replacing a mechanically retained vane is provided. The method comprises the steps of forming an oversized cavity (50) in an outer base (52), inserting a flared end (18) of a vane in the oversized cavity (50), and inserting a wedge (70) for mechanically retaining the flared end (18) of the vane in the oversized cavity (50).
