ISO 9001 Implementation Leads to Improvement in Sales

Their team members are among the most experienced in the industry, and the quality of their service is among the best in the world.

With its headquarters in Lincoln, Nebraska, Duncan Aviation employs approximately 2,800 team members worldwide.

The Challenge

For nearly 40 years, Duncan Aviation has supported many Original Equipment Manufacturers (OEMs) by manufacturing various interior components and bracketry for refurbishment projects through their FAA PMA Parts Manufacturing Approval (PMA) authorization. In 2020, they saw a strategic opportunity to launch a new enterprise division called Duncan Manufacturing Solutions (DMS). By adding more sophisticated equipment to supplement its previous capabilities and machinery, DMA was able to continue to build successful partnerships with OEMs and provide elevated service and support to their mutual customers.

Scott Stenka, DMS manager contacted Mike Nagle, associate director of the Nebraska MEP regarding the need for ISO:9001 and AS9100D certification. This certification is the international standard for Quality Management Systems for aviation manufacturing organizations. It dictates system requirements with the challenges of the aviation industry in mind and is required for government and aviation parts manufacturing support contracts.

The Solution

In the fall of 2021, Scott Stenka, manager Duncan Manufacturing Solutions, met with Mike Nagle, Associate Director of the Nebraska Manufacturing Extension Partnership (MEP) who introduced Dan Johnson of Husker Quality Management Systems. Johnson met with Duncan over a six-month period to prepare the company for ISO certifications and the auditing process.
