Airwolf Aerospace Receives EASA STC Approvals for True Blue Power® Batteries in Eight Helicopter Models

Airwolf Aerospace receives supplemental type certificate (STC) approval from the European Union Aviation Safety Agency (EASA) for the installation of True Blue Power® main ship batteries.

The EASA STCs cover the True Blue Power® TB20 lithium-ion batteries in Airbus AS350/AS355 helicopters and the True Blue Power® TB17 lithium-ion batteries in the following four makes and nine models of helicopters:

TB17 (17AH) — EASA STC 100855641; Transport Canada SH24-32; FAA STC SR04637CH; ANAC 2024S11-10

• Airbus H125/AS350, AS355, EC-120, H130/EC130
• Bell 206A/B, 206L/L1/L3/L4
• Enstrom 480B
• MD 369/500
• Hiller UH-12E (FAA, Transport Canada)

TB20 (20AH) — EASA STC 10085637; Transport Canada SH24-33; FAA STC SR04644CH

• Airbus H125/AS350, AS355

The field-proven, technical standard order (TSO)-certified True Blue Power® TB17 and TB20 lithium-ion batteries provide significant advantages, including:

• Lower weight—up to 63 percent lighter, increasing useful load
• Faster, cooler engine starts—higher voltage for reliable powerful starts
• Extremely fast charging—a full battery 4-10 minutes after start
• Longer life—8-year average
• Reduced maintenance with two-year maintenance cycle (TB17) and on condition (TB20)—no need for excessive damaging cap checks and Ni-Cd maintenance
• Extreme-cold capable—automatic built-in heater.

Airwolf Aerospace’s lithium-ion battery STCs were approved by the U.S. Federal Aviation Administration (FAA) in early 2024. The ANAC Brazil and Transport Canada STC approvals came in late 2024.
