STC SA12345SO

STC SA12345SO authorizes installation of an upgraded Cabin Pressure and Environmental Monitoring System (CPEMS) for select Avion 1200 / Avion 1300 / Avion 1400 aircraft.

The modification replaces legacy pneumatic and analog systems with a digital pressure control and monitoring suite that includes automated cabin pressure scheduling, environmental data logging, and fault alerting.

This retrofit improves crew situational awareness, enhances data reliability, and integrates with existing aircraft annunciation and air data systems while maintaining certification alignment with FAA Part 23 and 25 requirements.
