Texas Aerospace Technologies has received supplemental type certificate (STC) approval for installation of True Blue Power’s TS28 TS28 emergency battery power supply. The unit—a drop-in replacement for the Radiant CBS28-1—is TSO certified and uses nickel metal hydride technology, which helps operators reduce costs by providing improved performance, extended battery life, and more energy per cell compared to nickel-cadmium batteries.

The TS28 is now approved for use in the Cessna Citation II, Excel, Citation III, Sovereign, Latitude, and Longitude, demonstrating the company’s ability to work with OEMs to deliver avionics solutions that prioritize safety, efficiency, and innovation.

“Securing the STC for the True Blue Power TS28 is a testament to our team’s dedication and expertise,” explained Texas Aerospace CEO Cisco Hernandez. “This certification allows us to offer a powerful emergency battery power supply solution that provides peace of mind for pilots and operators, knowing their lighting systems will have backup power when needed most.”
