True Blue Power, a subsidiary of Mid-Continent Instruments and Avionics, has announced FAA approval of a supplemental type certificate (STC) for its Gen5 TB50 lithium-ion main ship batteries for the Gulfstream IV, G450, V, and G550 jets.

The STC was developed by 101 Aviation in partnership with Aloft AeroArchitects, and according to Van Winter, Mid-Continent’s s-v-p of sales and marketing, it encompasses approximately 1,200 airframes, half of which are the G550. While True Blue produces Li-ion batteries for aircraft down to the Cessna 172, it moves into a higher weight class with the G550 battery STC.
