Zusammenfassung:	A variable vane assembly (44) for a gas turbine engine includes a casing (50). The assembly comprises a variable vane (52) which includes a radially inner spindle (70) and a radially outer spindle (54). The radially inner and outer spindles are configured to rotatably couple the vane within the gas turbine engine. At least one of the radially inner and radially outer spindles comprises at least one groove (80) defined therein, at least one groove comprises at least one machined face (86), and a retainer for engaging the groove at least one machined face to securely couple the variable vane within the gas turbine engine, the retainer is configured to facilitate reducing wear of the variable vane.
