Duncan Aviation has extended its blended winglets authorisation from Aviation Partners, Inc (API), designating the company's Provo, Utah maintenance, repair and overhaul location as an authorised installer for API blended winglets.

“Duncan Aviation and Aviation Partners have been industry partners for years,” says Duncan Aviation's PVU executive vice president/chief operating officer Chad Doehring. “Having our Provo facility API-authorised gives our western US customers a more convenient option for winglet installations.”

In 2008, Duncan Aviation partnered with API and the OEM to install the API blended winglets on a Falcon 2000EX for STC (supplemental type certificate) certification flight test. API subsequently announced Duncan Aviation's Battle Creek, Michigan, and Lincoln, Nebraska MROs as the first authorised installers for Falcon blended winglets in 2009.

Duncan Aviation has 10 airframe maintenance teams between all three MRO locations with more than 10 years of experience completing this in-demand modification on all series of the Falcon 50, 900 and 2000 aircraft.

“Our relationship with Duncan Aviation goes back to the mid-1990s when we completed several Gulfstream II winglet installations. Dozens of Hawker 800 series winglet retrofits followed. With more than 100 Falcon winglets now complete, Duncan Aviation is our longest-standing and our most prolific installation partner,” says API president Gary Dunn. “We look forward to the increased installation capacity and customer choice that adding Provo to the list will bring.”

“It's been a great working relationship,” adds Doehring. “We appreciate API's continued support and confidence in the quality of our installations. It is confidence shared by our mutual customers.”

In addition to the Falcon 50, 900 and 2000 aircraft families, Duncan Aviation is also an API authorised installation partner for winglet modifications on Hawker 800 series aircraft.
