SUM Air has chosen AMOS as its digital maintenance and engineering platform, with the announcement dated 28 May 2026. Swiss-AS identified the South Korean start-up as the fourth airline in South Korea to implement the system.
The move is tied to SUM Air’s first aircraft delivery and its broader fleet expansion plans. The airline is using AMOS for maintenance and engineering rather than for fleet acquisition, underscoring the operational focus of the decision.
Industry coverage published on 28 and 29 May 2026 carried the same core message: SUM Air has gone live with, or is adopting, AMOS to support growth and streamline maintenance processes. No consolidated fleet-size target was confirmed in the available material, and the nature of the first delivered aircraft was not central to the announcement.
