Stator vane assembly with an attachment assembly

A stator vane assembly defining a chordwise direction and a crosswise direction perpendicular to the chordwise direction, the stator vane assembly comprising:

• an attachment plate;
• and
• an attachment assembly coupled to the attachment plate, the attachment assembly comprising:
• a first flange member attached to the attachment plate and extending along the chordwise direction;
• a second flange member attached to the attachment plate and extending along the chordwise direction, the first flange member spaced from the second flange member in the crosswise direction;
• a crosswise support member extending between the first and second flange members and positioned between the attachment plate and the first flange member and between the attachment plate and the second flange member;
• wherein the attachment plate defines an attachment plane, wherein the attachment assembly further comprises a base extension coupled to or formed integrally with the crosswise support member and extending into an opening of the attachment plate past the attachment plane;
• and
• wherein the base extension defines an interference fit with the opening of the attachment plate.
