• HPT cable found sheared on a jet engine

What did GE's analytics software find?

On March 14th, the GE SmartSignal solution detected a positive shift in exhaust gas temperature (EGT) of 10°C (50°F) with a 75 kg/hr of fuel flow (FF) change. The customer analyst monitored the engine and submitted a ticket to investigate at the next available opportunity.


What was the underlying cause?

Upon investigation, the technician found that the high pressure turbine (HPT) cable to direct air for case cooling was sheared. The sheared cable was subsequently replaced and the jet was returned to service.


What was the value to the customer?

Due to the early notification from the SmartSignal software, the customer discovered the sheared cable long before it would have been noticed through other tools or inspection methods. Operating under this condition caused the engine to be much less efficient. The customer estimated early notification resulted in a fuel savings of $10,000.
