Duncan Aviation recently installed its first two Tamarack Atlas Winglets on Cessna CitationJet models. Tamarack appointed Duncan an authorized installer in April and the Lincoln, Nebraska-headquartered MRO since modified a CJ1 and a CJ3 with the new winglets.
Delivered last week, the CJ1 additionally underwent airframe inspections, paint, and other modifications. Duncan also has installed the winglets on a CJ3 that further was undergoing a Pro Line Fusion flight deck upgrade.
The Tamarack winglets join the hundreds of other winglets that Duncan has installed over the last few years, the company said. The active winglets, however, can be installed without structural reinforcement, resulting in time and cost savings, Duncan added.
Approved by the FAA, EASA, Brazilian ANAC, and Transport Canada on CJs ranging from the original CJ up to the CJ3+, the winglets increase range, boost maximum zero fuel weight, reduce time to climb, increase climb gradients, improve single-engine climb performance, and provide ride stability. The system includes a wingtip extension, tuned winglets, and load-alleviation technology that counteracts gust and maneuvers wing-loading events.
