Approved For Installation On Cessna CJ Business Jets

The FAA has granted an STC To Tamarack Aerospace Group, for its Active Winglet system for the Cessna CJ business jet. The FAA STC follows the validation of the European Aviation Safety Administration (EASA) STC granted Dec 23, 2015.

Tamarack now has approval for the installation of its Active Winglets on the Cessna CJ, CJ1, CJ1+ & M2 in the US and all of Europe.  Customers will enjoy fuel savings (25% for the CJ & CJ1, 13% for the CJ1+ & M2), a range increase, higher initial altitudes, faster climbs, a 400lb MZFW increase, 12-15% higher single engine climb gradients, better high-hot performance and a significant stability increase.

Tamarack’s revolutionary and patented Active Winglet system is unique because it is comprised of a wing tip extension, a highly tuned winglet and load alleviation technology. The combination of winglet and wing tip extension significantly increases the wing’s aspect ratio and efficiency, resulting in substantial performance improvements and fuel savings, typically 3 to 4 times that of a passive winglet. The patented load alleviation technology works by counteracting and alleviating gust loads and maneuver loads so there is no need for wing structural reinforcement. In contrast, all traditional (passive) winglets are compromised designs balancing winglet efficiency against the additional weight of the required wing reinforcement. By eliminating structural reinforcements, the time required for Active Winglet installation is dramatically reduced.

Fatigue life extension, and gross weight increases are also possible with Tamarack’s Active Winglet system. The technology is scalable and can be installed on any aircraft type.  Additional airframe programs are in-development.

“The importance of the FAA approval cannot be understated," said Tamarack CEO Nick Guida. "We have a long list of orders and our customers are actively working with our  partner, Cessna, on scheduling installs. With the STC behind us, we expect a significant number of new orders from customers who have waited for certification.”
