South Korean start-up carrier SUM Air has gone live with the AMOS maintenance and engineering platform from Swiss AviationSoftware (Swiss-AS), creating a scalable digital foundation ahead of its first aircraft delivery.
The move makes SUM Air the fourth South Korean airline to adopt AMOS, using the integrated system to streamline maintenance operations, improve efficiency and support long-term expansion. The platform provides full oversight of maintenance planning, real-time execution tracking and regulatory compliance, helping the airline scale operations without added complexity.
SUM Air has also introduced AMOSmobile/EXEC and AMOSmobile/STORES, enabling mechanics and store personnel to manage tasks, inventory and maintenance records through mobile devices in a fully paperless workflow. The digital tools are designed to reduce turnaround times, eliminate paperwork and support faster operational decision-making.
The airline currently operates a single ATR 72 on domestic services and plans to expand internationally. AMOS will serve as the operational backbone for future fleet and network growth. SUM Air is the fourth South Korean airline to implement AMOS © SWISS-AS
