A single piece steel body for use in a governor assembly of a ram air turbine being characterised in that it comprises: a hub section that has a cylindrical hub orifice passing therethrough, the hub orifice having an axis of rotation and the hub section extending from a first radial plane normal to the axis of rotation of the hub orifice to a second radial plane normal to the axis of rotation of the hub orifice; an annular collar section that surrounds the hub section between a third radial plane normal to the axis of rotation and the second radial plane, the third radial plane being closer to the first radial plane than is the second radial plane; a counterweight section in the form of a ring segment that extends out of the annular collar section between a first surface of revolution about the axis of rotation that has a diameter larger than the hub orifice and a second surface of revolution about the axis of rotation of the hub orifice that has a diameter larger than the first surface of revolution, from a first axial plane that intersects the axis of rotation of the hub orifice to a second axial plane that intersects the axis of rotation of the hub orifice that is displaced from the first axial plane by an angle, and from the second radial plane to a fourth radial plane normal to the axis of rotation of the hub orifice, the fourth radial plane farther from the first radial plane than the second radial plane; and a crank arm section that extends out of the annular collar section in the general form of a closed cylinder, with a cylindrical bore therein having an axis of rotation generally parallel to the axis of rotation of the hub orifice, displaced from the axis of rotation of the hub orifice by a desired distance along a third axial plane that intersects the axis of rotation of the hub orifice. a hub section that has a cylindrical hub orifice passing therethrough, the hub orifice having an axis of rotation and the hub section extending from a first radial plane normal to the axis of rotation of the hub orifice to a second radial plane normal to the axis of rotation of the hub orifice; an annular collar section that surrounds the hub section between a third radial plane normal to the axis of rotation and the second radial plane, the third radial plane being closer to the first radial plane than is the second radial plane; a counterweight section in the form of a ring segment that extends out of the annular collar section between a first surface of revolution about the axis of rotation that has a diameter larger than the hub orifice and a second surface of revolution about the axis of rotation of the hub orifice that has a diameter larger than the first surface of revolution, from a first axial plane that intersects the axis of rotation of the hub orifice to a second axial plane that intersects the axis of rotation of the hub orifice that is displaced from the first axial plane by an angle, and from the second radial plane to a fourth radial plane normal to the axis of rotation of the hub orifice, the fourth radial plane farther from the first radial plane than the second radial plane; and a crank arm section that extends out of the annular collar section in the general form of a closed cylinder, with a cylindrical bore therein having an axis of rotation generally parallel to the axis of rotation of the hub orifice, displaced from the axis of rotation of the hub orifice by a desired distance along a third axial plane that intersects the axis of rotation of the hub orifice.
