True Blue Power Granted FAA STC For Lithium-ion Batteries


True Blue Power announced the Federal Aviation Administration (FAA) has granted a Supplemental Type Certificate (STC) for the company’s TB17 (17-amp hour) lithium-ion batteries on Robinson R44 helicopters. This is the first STC granted by the FAA for lithium-ion battery use as a primary electrical power source, including engine start. True Blue Power partnered with St. Louis Helicopter, LLC to secure the STC.

“We are extremely proud that the TB17 has received the FAA’s first lithium-ion main ship battery STC,” said Rick Slater, Director, True Blue Power. “With this approval, the FAA recognizes that True Blue Power lithium-ion products are safe, effective, and a viable source of main ship power. This is their stamp of approval and it is groundbreaking.” Slater added.

“The TB17 is a perfect solution for R44 owners and operators,” said Jim Robinson, President, St. Louis Helicopter. “Weighing less than 16 pounds, the TB17 is 40 percent lighter than the factory provided battery. Upgrading to the TB17 provides R44 operators the benefit of increased payload, faster engine starts, significantly reduced maintenance cost, and more than double the useful battery life. We found those benefits, combined with the visibility of the ACU to monitor and report battery status, to be ideal for our customers and R44 operators worldwide.”

True Blue Power operates within an AS9100C certified facility and specializes in the custom design and manufacture of advanced power solutions for the global aerospace industry. Select products feature proprietary Nanophosphate(R) lithium-ion cell chemistry, which provides unmatched power, energy, safety, and life. Along with receiving the FAA’s first STC approval, True Blue Power is the first company in the world to achieve FAA TSO and EASA ETSO certification for lithium-ion batteries.

The TB17 lithium-ion battery and other True Blue Power products will be on display at the True Blue Power exhibit #2050 during the 2016 National Business Aviation Association (NBAA) Convention and Exhibition, at the Orange County Convention Center in Orlando, Florida.
