A method and fixture assembly for assisting in the matching and assembly of components of a variable stator vane assembly of a gas turbine engine. The method generally entails a stator vane configured to be assembled to a casing with a spacer. The vane has a surface at a perimeter thereof and a seat offset from the surface. The spacer to which the vane is to be assembled has first and second surfaces offset relative to each other, the first surface being adapted to engage the seat of the vane and the second surface adapted to face the surface of the vane. The vane is installed within an opening in the casing so that a first sealing member is between the casing and the vane, the casing is between the first sealing member and a second sealing member, and the seat extends through the opening. A fixture is then mounted to the vane so that the casing and the first and second sealing members are clamped between the fixture and the vane under a load. The position of the seat of the vane is then detected, and a spacer is selected having an offset dimension between its first and second surfaces based on the position of the seat.

[What is claimed is:] [1.]providing a variable stator vane for a gas turbine engine, the vane having a surface and a seat offset from the surface, the vane being configured to be assembled with a spacer having first and second surfaces offset relative to each other, the spacer and the vane being configured such that, when the spacer is assembled to the vane, the first surface of the spacer engages the seat of the vane and the second surface of the spacer faces the surface of the vane;installing the vane within an opening in a casing so that a first sealing means is between the casing and the surface of the vane, the casing is between the first sealing means and a second sealing means, and the seat extends through the opening;mounting a fixture to the vane so that the casing and the first and second sealing means are clamped between a surface of the fixture and the surface of the vane under a clamping load;detecting a position of the seat of the vane; and thenselecting a spacer having an offset dimension between the first and second surfaces thereof based on the position of the seat.
