Engine Maintenance Data Visualization Solution


A familiar problem: you collect all the data you can about your do you then turn it into usable and valuable insights?

One of our clients faced this problem. They had amassed years’ of data about the aircraft engine maintenance and repairs they do for customers. Due to the size and complexity of aircraft engines, this means a lot of information, captured primarily in Excel. Our client knew that insights were hiding in this data - potentially millions of dollars of savings and improvements. They engaged us to convert this data to those insights.


Together, we envisioned a data visualization solution to analyze maintenance and repair data. We created Tableau and PowerBI visualizations of different types of repairs, trends over time and by location, detailed views of repairs on specific engine parts, and other statistical models.

We paired up with our client's statistics guru to create the right mathematical models using R, an open source programming language for statistical computing and creating visualizations.

The solution enables our client to see what engines meet certain maintenance requirements, so they can be sold, used, and repaired differently. These findings drove changes in preemptive maintenance schedules, which extend the life of the aircraft engines. This translates into significant savings from reduced maintenance and operation costs.


This data visualization solution helped our client far exceed their goal of finding $1 million in savings. The tool made it clear that by servicing a specific part more often, they can save a huge amount of money on total engine repairs over the course of time. These savings totaled to over $3 million. Huge savings like these show the value of stepping back and looking at your data differently; you never know what insights you might uncover.
