A stator vane includes an airfoil having an airfoil shape. The airfoil shape has a nominal profile substantially in accordance with Cartesian coordinate values of X, Y, and Z set forth in one of TABLE I, TABLE II, or TABLE III. The Cartesian coordinate values of X, Y, and Z are defined relative to a point data origin at a base of the airfoil. The Cartesian coordinate values of X, Y, and Z are non-dimensional values that are convertible to dimensional distances expressed in a unit of distance by multiplying the Cartesian coordinate values of X, Y, and Z by a scaling factor of the airfoil in the unit of distance. The X and Y values are connected by smooth continuing arcs to define airfoil profile sections at each Z value. The airfoil profile sections at Z values are joined smoothly with one another to form a complete airfoil shape.

A system for repairing dovetail slots includes a slot adaptor having a body configured and disposed to nest between first and second side walls of a dovetail slot, and a tool holder configured to be coupled with the slot adaptor. The tool holder includes a tool guidance system configured and disposed to direct a tool into contact with one of the first and second side walls of the dovetail slot. A cutting tool is mounted in the tool holder. The cutting tool includes a tapered surface configured and disposed to form a tapered recess in the one of the first and second side walls of the dovetail slot.
