INTERNATIONAL AERO Engines (IAE) has excluded some early production V2500-A1 engines from Airbus A320 extended-range twin operations (ETOPS) until it completes a retrofit of redesigned compressor blades.
IAE says that no A320 operators are directly affected. A test of the redesigned blade is expected soon, IAE adds, and is acting to correct the problem, which last appeared on a Dragonair A320 in February. The redesign is aimed at strengthening blades which failed in the high-pressure compressor after clearance problems between the blade tips and the compressor casing were caused by shaft flexing.
