Southeast Aerospace (SEA) has received a supplemental type certificate (STC) from the FAA for the installation of the Garmin GI 275 on Part 25 aircraft. SEA partnered with Garmin and Peregrine to develop a solution that allows for the cost-effective replacement of mechanical and electronic flight instruments on Part 25 aircraft.

The GI 275 is designed to take advantage of the common 3.125-inch flight instrument size, reducing installation time and preserving the existing aircraft panel. SEA designed and manufactured a 3.125-inch adapter plate to further simplify installation. The adapter plate is available for purchase with the STC.
