Duncan Aviation Component Repair Growth: It Takes A Village

Posted by Diane Heiserman on Thu, Mar 01, 2018 @ 09:00 AM

Early on, when the Duncan Aviation avionics, instrument and accessory component repair shops were established, we recognized that our success wasn’t going to come on its own just because we opened our doors. From the beginning, we have developed connections and nurtured relationships with many of our OEM industry partners.

Since 1973, we have signed partnering agreements with more than 25 OEMs. These connections are a priority for Duncan Aviation because they lead to a better experience for our mutual customers.

It was important to build those relationships in the 1950s when Founder Donald Duncan was selling aircraft, and it is crucial today as we continue to grow our components repair services.

Below are three of our valued OEM partnerships


As a result of their vast experience with and knowledge of legacy instruments and components, L3 Aviation Products was pleased to sign a service agreement with Duncan Aviation, allowing them to provide service and support of legacy mechanical gyros and power supplies.

ACSS and Duncan Aviation also collaborated on the development of the AML STC in support of the ADS-B Out program, providing a turnkey solution for business jet operators.

The alliance between L3 and Duncan Aviation spans nearly 45 years. My L3 contacts are quick to answer any questions I have and are committed to making sure we are up-to-date on all the latest repair procedures, offering factory training anytime we request it. When it comes to parts, L3’s response time is reliably quick, allowing us to be more responsive to our customers. We see many L3 units in our shop. 


There are many benefits to aligning ourselves with authorized channel partners such as Duncan Aviation. Chief among them is that our mutual customers have a better experience. Duncan Aviation has collaborated with Honeywell for more than 40 years, delivering a consistent message, pricing, and quality component service. The relationship between Honeywell and Duncan Aviation is extremely good regarding our sales and customer business team. Our ability to communicate candidly and work together is remarkable. I credit Duncan Aviation’s sales staff and leadership team for helping us grow the partnership.

Having an established, trusted relationship with the OEMs always benefits the end-user. In many cases, we openly collaborate with manufacturers to provide new services or work though problems that result in improved product quality and better customer relations. By giving us access to updated OEM manuals and access to parts for older units, we provide quicker turntimes, higher quality repairs, and a resource that helps keep legacy aircraft flying.

Installing and maintaining aircraft avionics and cabin systems is complicated business. To best serve our mutual customers’ needs and wants, Duncan Aviation and Rockwell Collins have forged a 50-year working relationship based on a foundation of trust and effective communication. By sharing our collective knowledge, technical information, and skills, we serve our common customers as a team. To demonstrate this, we recently named Duncan Aviation an authorized service provider for repair, service and modification of the Collins TDR-94 and TDR-94D transponders. They are able to repair, install and upgrade modifications of these units at their main facility in Lincoln, Nebraska, as well as through their satellite avionics facilities located throughout the United States. Together we make the business of maintaining aircraft avionics and cabin systems easier to navigate.

As I work with Rockwell Collins, it is easy to see they have the end-customer’s best interest in mind. Our authorization to perform the upgrade on the Rockwell Collins TDR94/94D units speaks volumes about the trust they have in our capabilities to support the Rockwell Collins brand. They go out of their way to make sure we have what we need in order to meet the needs of our customers. I would stand by Rockwell Collins all day long. My contact there has never failed me.
