Tamarack Aerospace Receives FAA Approval for Active Winglets

Jan. 3, 2017
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.

(Sandpoint, Idaho, January 3rd, 2017) - Tamarack® Aerospace Group, Inc. announced today that it received U.S. Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) 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, a range increase, higher initial altitudes, faster climbs, a 400 lb 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.

Tamaracks CEO Nick Guida stated, “The importance of the FAA approval cannot be understated. 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.”

Tamarack® Aerospace Group, Inc.

Idaho based Tamarack Aerospace Group Inc. invented and patented the revolutionary Active Winglet system. Tamarack’s certified Active Winglets are three to four times more efficient than passive (traditional) winglets. The Active Winglet system typically provides a 12-18% reduction in fuel burn, performance gains and increased asset value. The Active Winglet system is comprised of a wing tip extension, a highly tuned winglet, and load alleviation technology. The load alleviation system counteracts gust or maneuvre wing loading events and eliminates the heavy wing reinforcement and structural additions required by all passive winglets.

In 2013, Tamarack set an unofficial world record by flying 1853nm (26 kt tailwind) in an Active Winglet equipped Cessna CJ.  In 2016 Tamarack flew a CJ3 2037 nm (25 kt tailwind) at MMO, landing with 1130 lbs. of fuel on-board.
