Safety message
While the distress to the HPT was severe enough in this case to result in an in-flight engine shutdown, the associated risks to the safety of continued flight were relatively low, given the failure had been contained and the operator’s procedures were effective in managing the engine shut down. This occurrence also pointed to the value of real-time engine condition monitoring, since advanced warning of engine degradation and efficiency loss allows inspection and corrective action before damage progresses to a level where it can cause an in-flight shut down.
If the real-time engine condition monitoring was doing its job, the problem would have been detected and this shutdown would not have occurred.
