Korean Air has years worth of historical maintenance records for hundreds of aircrafts in its fleet. But until recently, this vast amount of critical data was virtually unsearchable. That meant that maintenance technicians had to diagnose and fix issues without being able to tap into or interpret implications from valuable past learnings and courses of action.
Watson ingested structured and unstructured data from multiple sources including technical guidelines, non-routine logs, technician notes, inventory, trouble shooting time and material cost data, and in-flight incident history.

Further, if an issue occurs in flight, the cabin crew can report it immediately to ground operations. Watson will access data from similar issues in the past and compare this information against technical guidelines including necessary materials and fixing time. Maintenance technicians fix the issue on the ground and enter their actions into the system to add to Watson’s knowledge.
With Watson, maintenance managers can also identify trends of issues in each season and can take these insights to the original equipment manufacturers for improvement.
Korean Air needs their over 2,000 maintenance employees to be able to act faster. When Watson delivered actionable insights on the root causes and solutions of issues, Korean Air shortened its maintenance defect history analysis lead times by 90%.
The maintenance employee can now see patterns of defect and failure on equipment to make preventive maintenance allowing them to spend more time getting people places on time—and working to keep their 25 million passengers happy.
Airlines, hospitals, businesses, educators and governments are working with Watson. In 45 countries and 20 industries, Watson is helping people make sense of data so they can make better decisions while uncovering new ideas.
