Tamarack Aerospace has received STC approval from both EASA and the FAA for its active winglet system for the Cessna Citation 525, the Sandpoint, Idaho-based company announced today. These approvals cover installation of the winglets on the Cessna CJ, CJ1, CJ1+ and M2 in the U.S. and Europe.

The company’s winglet system includes a wingtip extension and winglet, as well as load-alleviation technology that counteracts and alleviates gust loads and maneuver loads, negating the need for structural reinforcement of the wing. By eliminating structural reinforcements, the Tamarack winglet “dramatically reduces,” installation time, said the company.

According to Tamarack, performance benefits of the winglets include fuel-burn reduction and range increase of up to 25 percent for the CitationJet and CJ1 and up to 13 percent for the CJ1+ and M2; higher initial altitudes; faster climbs; a 400-pound increase in zero fuel weight; 12- to 15 percent higher single-engine climb gradients; better high-hot performance; and increased stability.

“We have a long list of orders, and our customers are actively working with our partner, Cessna Aircraft, on scheduling installs," said Tamarack CEO Nick Guida. He added that the technology is scalable and can be installed on any aircraft type. Additional airframe programs are already in development.
