South Korean start-up SUM Air has adopted Swiss AviationSoftware’s AMOS maintenance and engineering platform as its digital backbone ahead of fleet expansion. The implementation was completed in April 2026 and supports the airline’s first aircraft delivery and initial operations.
Swiss-AS said SUM Air is the fourth South Korean airline to implement AMOS, extending the software’s footprint in a market where carriers are increasingly standardising maintenance and engineering processes on integrated MRO systems. SUM Air currently operates one ATR 72 aircraft on domestic routes and expects to expand further in the coming years.
The airline also selected AMOSmobile/EXEC and AMOSmobile/STORES to support maintenance execution and stores processes. Swiss-AS said the platform gives SUM Air control over maintenance planning, real-time execution tracking and compliance as the carrier scales from start-up operations to broader network growth.
