Zusammenfassung:PROBLEM TO BE SOLVED: To provide a modified variable stator vane assembly and a modified bushing thereof. SOLUTION: A variable stator vane assembly 10. The assembly includes a rotatable trunnion 12 and a first metal bushing 14. The trunnion is capable of being located in a through hole extending between outer and inner surfaces 18 and 20 of a compressor casing 22 of a gas turbine engine 24. The first metal bushing is capable of being located in the through hole proximate the outer surface to surround a first portion 26 of the trunnion when the trunnion is located in the through hole. The first metal bushing and the first portion have wear-resistant coatings which are in mutual contact, apart from any intervening lubricant, when the trunnion and the first metal bushing are located in the through hole and the trunnion is rotating with respect to the first metal bushing.
