Blackhawk Aerospace Technologies (BAT) has completed the supplemental type certificate (STC) for the installation of the Garmin GI 275 electronic standby instrument system for the Cessna Citation 500/501/550/S550/560/560XL series jets. According to the Columbia, Missouri-based company, the approved model list STC applies to all serial numbers of these Citation models.
Blackhawk said the upgrade offers a less expensive and easily installed alternative—along with a provided PMA kit—to the costly and difficult-to-repair original standby instrument system. The STC allows the option for use of an internal lithium-battery-powered GI 275 or the existing standby battery system.
The data package includes the aircraft-specific airspeed markings to ensure the correct installation of the GI 275. It also allows for the installation of options such as synthetic vision, backup GPS antenna, and heading magnetometer.
“Our customers were looking for a turnkey solution to an age-old program for the Citation 500-series aircraft,” said Blackhawk v-p of sales and marketing Conrad Theisen. “We listened and developed an STC designed by installers for installers for a low-cost solution.”
Customers can purchase the STC and PMA kit through the Garmin dealer network or at Blackhawk Aerospace Technologies in Columbia.
