Aviation Partners (API) has extended its blended winglets installation authorization to Duncan Aviation’s MRO facility in Provo, Utah. The agreement builds on similar authorizations at Duncan’s MROs in Lincoln, Nebraska, and Battle Creek, Michigan.

“Duncan Aviation and Aviation Partners have been industry partners for years,” said Duncan Provo executive v-p and chief operating officer Chad Doehring. “Having our Provo facility API-authorized gives our western U.S. customers a more convenient option for winglet installations.”

Fourteen years ago, Duncan, API, and Dassault partnered on the installation of API blended winglets on a Falcon 2000EX for STC flight testing. A year later, API designated Duncan’s Lincoln and Battle Creek sites as authorized installers of its blended winglets on Falcon jets.

Ten airframe teams at Duncan’s three MRO facilities have a decade of experience completing more than 100 blended winglet installations on Falcon 50s, 900s, and 2000s. Further, in the mid-1990s Duncan completed several Gulfstream II and dozens of Hawker 800 winglet installations. “Duncan Aviation is our longest-standing, and our most prolific, installation partner,” said API president Gary Dunn.
