Read more about our Senior Leadership Team.


Duncan Aviation was founded by Donald Duncan, an Iowa farmer and automobile salesman. He learned to fly in the 1950s and as he gained aircraft experience and developed deep friendships with other aviators, he discovered an opportunity. He heard business operators asking to utilize aircraft as business tools, so in 1956 he bought into a Beechcraft distributorship that would become Duncan Aviation.

Customer Survey Responses

Customers consistently tell us they want high-quality service, excellent project coordination / communication, and on-time delivery. We have long focused on these things. Here is our performance in 2019. 

Project Coordination


High-Quality Service


On-Time Delivery


Based on feedback from customers, project coordination is interpreted to include the technical knowledge of the assigned project manager, the planning, the communication the customer received throughout the project, and the use of our online myDuncan project management tool. On this aspect, Duncan Aviation’s rating for 2019 was 4.81 out of 5.

When it comes to quality, customers rate the work of the team leaders and technicians completing the aircraft project. In this area, Duncan Aviation customers give us a rating of 4.82 out of 5.

In the on-time delivery category, the customer chooses from the set options of early, on-time, or late. We don’t ask about things that often affect delivery schedules, like work add-ons, parts availability, or unforeseen repairs. In this area, Duncan Aviation customers give the timeliness of their delivery a rating of 4.1 out of 5.

We take these surveys very seriously. We share them with our team members, celebrating good survey results and striving to learn from both great and less-than-great responses. Of course there is room for improvement. Someday, we’d love to have full five-star ratings, but we fully expect and appreciate our customers continuing to raise the bar. We will continue to improve and continue to ask customers for their honest feedback and ideas.
