In continuation with the earlier investigation of a particular type of aeroengine build (NAL report No. MT-FA-945-09-2005 and MT-FA-945A-01-2006), intermediate casing was also sent to the laboratory for investigation. Examination revealed a crack along the fillet of the mounting area. Fractographic examination confirmed this crack to be a fatigue crack. This corroborates the earlier findings wherein it was established that high alternating stresses and/or vibration were transmitted to No.3 bearing mounting flange through intermediate casing due to problems elsewhere in the engine.
