A West Air Sweden British Aerospace ATP, registration SE-MAH performing freight flight SWN-72T from Oslo to Trondheim (Norway), was enroute on autopilot in icing conditions at FL150 about 75nm north of Oslo when the airspeed decreased, the aircraft started shaking and becoming unstable. The crew disconnected the autopilot, regained control, descended the aircraft to FL130 and continued to destination for a safe landing.
Norway’s Statens Havarikommisjon for Transport rated the occurrence a serious incident and opened an investigation reporting the investigation currently suspects the failure of the anti ice systems at the tail plane.
