Tamarack Aerospace Group obtained U.S. FAA and European Aviation Safety Agency approvals for installation of its Atlas Active Winglets on the Cessna C525B CitationJet series. The approvals for the CJ3 and CJ3+ follow supplemental type certifications for installation of the winglets on the C525, which includes the CitationJet, CJ1, CJ1+, and M2 business jets. Tamarack secured the first nod from EASA in late 2015 and from the FAA a year later, but has since been expanding applications and added certifications. Along with the CJ3, certification for the CJ2 is anticipated to follow in April and work has begun on a program for installation on the Citation Excel, among others.

“Regulatory approval of our latest STC amendment for the Citation CJ3 and CJ3+ proves what our existing CJ owners have known since their installs,” said Tamarack Aerospace founder and CEO Nick Guida. “Active winglets on the C525, and now on the C525B, dramatically enhance the performance of the aircraft.”

Noting that the company flew a CJ3 with active winglets installed from Paris, Texas, to Paris, France, with one stop, Guida added, “With Atlas you can climb faster, fly farther, and burn less fuel.” Priced at $289,000 for the CJ3 and $319,000 for the CJ3+, the winglets boost range to 2,100 nm at maximum continuous thrust with IFR reserve, provide a maximum zero fuel weight increase of 400 pounds, enable direct climb to FL450 in 30 minutes or less, increase climb gradients, improve stability, and provide for higher maximum takeoff weight, Tamarack said.

As the company extends its portfolio, it also is expanding its capacity at its Sandpoint, Idaho facility. The expansion is enabling the company to offer a one-week installation (plus paint time) at the factory.

The Atlas winglets use a built-in load-alleviation device called Tacs (Tamarack Active Camber Surface), along with a wing extension and winglet to improve aerodynamics without the need for structural reinforcement. In addition to the winglets, the installation includes upgraded LED navigation and anti-collision lighting.
