Tamarack Aerospace Group has received US Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) for its Active Winglet system for the Cessna CJ business jet.

Prior to this, the company obtained the validation of the European Aviation Safety Administration (EASA) STC on 23 December 2015.

Tamarack will now install its Active Winglets on the Cessna CJ, CJ1, CJ1+ & M2 jets in the US and Europe. 

“The importance of the FAA approval cannot be understated."

Customers will get 25% fuel savings for the CJ & CJ1 and 13% for the CJ1+ & M2 jets.

Tamarack Aerospace Group CEO Nick Guida said: “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’s Active Winglet system consists of a wing tip extension, a tuned winglet and load alleviation technology.

The technology works by counteracting and alleviating gust loads and manoeuvre loads without wing structural reinforcement.

With the combination of winglet and wing tip extension, the wing’s aspect ratio will increase, resulting in performance improvements and fuel savings.

Fatigue life extension and gross weight increases are also possible with Tamarack’s Active Winglet technology, which is scalable and can be installed on any aircraft type.
