LINCOLN, NEB — Duncan Aviation, along with Winglet Technology, LLC, is pleased to announce their collaboration on FAA STC (Supplemental Type Certificate) certification testing of Winglet Technology’s Transitional Winglet design for the Cessna Citation Sovereign aircraft. 

In support of the certification process, Duncan Aviation installed the wing reinforcement on the Sovereign aircraft along with the winglet attach structure and Transitional Winglets. FAA certification flight testing was completed in late August.

The Transitional Winglet upgrade will provide Sovereign owners and operators with greater operational flexibility and performance benefits, such as increased speed at altitude, increased range /payload, improved time-to-climb, and more. 

Bob Kiser, President, Winglet Technology, anticipates the FAA STC will be complete by the end of 2016, with FAA approval during the first quarter of 2017. 

Duncan Aviation has been authorized by Winglet Technology to install the Transitional Winglet STC on the Citation X, and upon issuance of the FAA STC, plans to begin the first production Transitional Winglet installation on the Citation Sovereign during the first quarter of 2017.

“The Citation Sovereign is a solid aircraft with known reliability,” says Nick Huskey, Citation Service Sales Rep with Duncan Aviation. “Performance gains that come with the winglet upgrade are impressive. The increased speed and range absolutely speak for themselves and, of course, there is that ramp presence that is certain to turn heads.”  

Huskey goes on to say that Duncan Aviation is excited to partner with Winglet Technology to bring this new service to Citation Sovereign operators. “The Sovereign operator will be able to load the aircraft up and not have to worry about having to stop before reaching their destination,” he says.
