Next Steps In Harnessing Big Data For MRO

Engine makers have been using sensor data to monitor and manage the maintenance of engines for a long time. The technology is rapidly expanding to other components, and as coverage expands, analytical sophistication is likely to improve as well. This revolution is just beginning, and it will bring many changes both on the ground and in the air.

Everyone talks about performing predictive maintenance now, but what—beyond the fancy algorithms—is actually necessary to do it effectively? First, airline maintenance and other departments must make major changes in the way they do business on the ground. Cavok Vice President David Marcontell ticks off some key steps:

True prognostics require granular data about all maintenance and maintenance-related activities at every step, from onboard sensors through the supply chain. Prognostics will use machine learning and algorithms to identify trends in data captured in many places about the five Ws: who, what, when, where, and why?

Companies cannot burden technicians with data entry. The infrastructure must be there to capture data without additional work, by exploiting tools such as RFID tags and barcodes whenever possible. This also means technicians will need mobile devices to enter data electronically, without time-wasting trips to a kiosk or computer.

Mobile devices also must give maintenance engineers instant access to the results of predictive maintenance, the work orders, maintenance manuals and much else, right where they work, so they can execute the new approach, both on the line and in hangars.
Sustainable Trust in Results 

Mechanics must trust the results of predictive maintenance tools, and the accuracy of these tools must in turn justify this trust. Marcontell says the new generation of digital-savvy mechanics has learned to trust diagnostics, not just their own experience. But they will sometimes have to switch out $100,000 parts that appear to be functioning normally. If many of those removals turn out to be unnecessary, confidence can quickly be lost, and the whole effort might collapse.

Prognostics System That Closes the Loop 

As all maintenance activities must be tracked, so must all core steps: notification of discrepancies from technicians, cabin crew or pilots; tasks performed; work orders; materials; completion and the ultimate results.
