Blackhawk Announces Completion of STC for the Installation of Garmin GI-275 for the Citation Series Aircraft

COLUMBIA, Missouri – November 28, 2023 – Blackhawk Aerospace Technologies (BAT) has completed a Supplemental Type Certificate (STC) for the installation of the new Garmin GI-275 Electronic Standby Instrument System for the Citation 500/501/550/S550/560/560XL series aircraft. The Approved Model List (AML) STC is applicable to all serial number aircraft for these Citation models. The current Standby Instrument System in these aircraft have become difficult and very costly to repair. This provides a solution that is cost effective and easily installed along with a provided Parts Manufacturer Approval (PMA) kit.

The STC allows the option for use of an internal Lithium Battery-powered GI-275 or the existing Standby Battery System. The fully encompassing data package includes the aircraft-specific airspeed markings to assure the installation of the GI-275 is done correctly. Options for the GI-275, like Synthetic Vision, backup GPS antenna and heading magnetometer, can also be added at the time of installation.

“Our customers were looking for a turnkey solution to an age-old program for the Citation 500 series aircraft,” said Conrad Theisen, BAT’s VP of Sales & Marketing. “We listened and developed an STC designed by installers for installers for a low-cost solution.”

The STC and PMA kit are now available to purchase through the Garmin Dealer Network or at Blackhawk Aerospace Technologies in Columbia, Missouri.
