GE Aerospace and Scandinavian Airlines (SAS) have successfully concluded a predictive maintenance project aimed at improving the operational reliability and efficiency of SAS’s Embraer E190 fleet.

The collaboration focused on addressing common challenges associated with Bleed Systems and Flight Controls, governed under Air Transport Association (ATA) chapters 36 and 27. By utilizing GE Aerospace's Event Measurement System (EMS) flight data and analytics platform, coupled with SAS’s technical operations data, the project has enabled SAS to swiftly identify the root causes of maintenance issues and implement precise fixes.

SAS currently employs EMS to process flight data across its aircraft operations, along with GE Aerospace’s Safety Insight, Fuel Insight, and FlightPulse® software solutions. The efficacy of EMS in helping SAS enhance safety, efficiency, and reliability stems from its rapid data processing capabilities, the integration of multiple datasets, advanced analytics editing functions, and the capacity to quickly iterate and test algorithms against historical flight data. This approach has enabled SAS to significantly reduce the number of unscheduled maintenance events related to ATA chapters 36 and 27 and reduce the time aircraft were out of operation.

“We are excited to start a new era in how we do maintenance at our young company by rolling out the predictive analytics solutions from GE Aerospace, SaaS,” said Carlos Diaz Deutman, Technical Director as SAS Link. “We have already seen major improvements in our disruption rates, as well as a significant reduction in the exposure to safety hazards such as dual bleed loss. For SAS, Safety is first, and these models are also contributing in this sense, not only to On Time Performance and Completion Factor which are often the metrics monitored with Predictive Maintenance.”

“This project demonstrates the powerful impact of merging flight data with technical operations insights,” said Andrew Coleman, General Manager at GE Aerospace, Software as a Service. “We are excited to continue working with SAS and showcasing the potential of our EMS platform to optimize fleet performance and safety.”

Building on the success of this initiative, SAS and GE Aerospace are now exploring additional ATA chapters for future projects, employing the same data integration strategy. As SAS continues to expand its utilization of EMS, it is establishing GE Aerospace's flight data and analytics platform as its primary source of truth for safety, sustainability, and efficiency.
