Foremost as an industry, it would allow us to eliminate a large portion of human error (either fatal or not-fatal) by reducing the actual human involvement in all Maintenance related processes.

In my previous post I briefly outlined the three fundamentals for what we know as ‘Big-Data’. For those who missed it, allow me to give a quick summary:

Big data, or in other words: information of extreme size, diversity and complexity (this is a definition used by Gartner INC, one of the world leading institutes on IT) revolves around the capability of organisations (or any other institute for that matter..) to:

  1. Timely access and retain data;
  2. Analyse and interpret data;
  3. Base decision making on data

Data is being produced 24 hours a day, 7 days a week throughout your companies value chain. The challenge here is to be able to access this data (information), access it in a timely manner (it does not make sense to have access to last year’s data only two years afterwards), have the computing power to retain it, have the resources to interpret and analyse it and to allow your organisation to be driven by data instead of someone’s opinion.

So what can we do with this phenomenon of big-data and its three principles in Aircraft Maintenance? Before I go into the answer of this question, lets first of all get rid of the obvious answer:

Sure, we can gain operational efficiency and reduce costs if Airlines and Maintenance Companies would use data more effectively, but this is a narrow minded, “stuck-in-the-here-and-now” view of things. It completely misses the fact that big data in Aircraft Maintenance has the potential to fundamentally change the industry as a whole! In order to see the fundamental change we need to look beyond the borders of our own airline or maintenance company, and, without any pun intended, take a helicopter view on the industry.

Imagine that, for whatever reason (most probable for reasons of efficiency), most of the industry’s data is collected real-time into a platform (timely access & capacity to retain data…). Now add the capacity to analyse and interpret all this data and you have a fundamental change taking shape. Let’s illustrate based on an example:

Flight EX-1234 from New York JFK to Amsterdam-Schiphol, during flight the on-board maintenance systems indicate that one of the flight control computers is failing and needs to be replaced. Already during flight this is transmitted to the platform at which point it knows that a flight control computer is required, with an engineer to replace it, on Amsterdam airport for flight EX-1234 on its Estimated Time of Arrival. Now suppose that the platform would have access to the airline’s parts inventory to determine if a spare Flight Control Computer is available, where it is located and the estimated transit time to Amsterdam to get this part there. Now let’s take it one step further, and assume it also has access to the parts inventory of all other part suppliers, airlines and MROs. This enables the platform to check global availability of the flight control computer, the price and how soon it can be delivered in Amsterdam. In short, it would be able to completely automate the buying decision for airlines based on lead-time to delivery, quality and costs.

The latter example is based on a unscheduled maintenance situation, just imagine the impact on all those scheduled purchasing that takes place in the industry (safe to say that it would be around 70% of total purchases done in the industry…). Now let’s look at the engineer that we need in order to replace the flight control computer. The same principle applies here, it would be able to look into the staff availability within the airline’s rostering and determine if a suitable engineer can be made available on Amsterdam at the ETA of flight EX-1234 and what it would costs to get him there (if not already on the airport). Additionally, it would be able to source with other maintenance providers to see if they have the capacity to provide a proper licensed engineer to replace the flight control computer and list costs, quality and performance. Thus, also in this case, the planning cycle is fully automated. Again, this is an unscheduled scenario, just imagine the possibilities for scheduled maintenance. Hopefully by now you realise that we have eliminated the human factor all the way up until the moment the actual flight control computer needs to be physically replaced on the aircraft.

Elimination of most human involvement until the moment of actual maintenance being done, enables numerous efficiency gains and process streamlining: production of spare parts being based on actual need rather than commercial drive, full accuracy in aircraft record keeping, provisioning of maintenance capabilities based on actual need rather than competition, optimal use of tools & equipment on airports, proper aircraft lifecycle planning to reduce our environmental impact, and many additional positive affects you might identify yourself. Obviously all these improvements result in significantly lower maintenance costs and improved operational efficiency. However, foremost as an industry, it would allow us to eliminate a large portion of human error (either fatal or not-fatal) by reducing the actual human involvement in all Maintenance related processes.
