Abstract: A method and apparatus for rigging a variable stator vane arrangement (100) for a gas turbine engine (10) is provided. The arrangement provides at least two sets of rigging holes to an actuator (200), with the actuator extension during rigging being dependent on which of the sets of holes are aligned. This allows the actuator extension to be adjustable during rigging, thereby facilitating different relationships between actuator extension and variable vane angle in use.
