About Us

Providing Innovative Solutions Since 1984

We are a small, woman-owned parts distributor providing stocking services, engineering support, and application consultation headquartered in Derby, Kansas. Our sales reach across North America, serving Aerospace & Defense, Rail, and Shipboard industries. With more than 87 years of combined sales experience, it is safe to say, if you need it – we can get it to you.

A.C.E. was started by Jo Helmer and her son Mike. Later, Grant Helmer, Jo’s husband, joined the team bringing with him his 20 years of experience in the industry. When they started in 1984, they were working out of a small office behind their house and, by 1991, had grown enough to open an office in Rose Hill, Kansas.  Through the years A.C.E. has moved locations a few times but is still maintained and managed by Jo and Mike.  Since then, Aircraft & Commercial Enterprises has grown to include an outstanding sales team from all parts of the US. After 37 years in business, we are still a family run business locally owned and operated in Derby.

Our specialties include a variety of products and services to include: the distribution of connectors, backshells, wire & cable identification systems, wire harness protection products, and more. In addition, we provide custom solutions for armored land vehicles, communication equipment, space & missiles, unmanned aircraft, and military aircraft. Above all, Aircraft & Commercial Enterprises prioritizes quality and customer satisfaction.


Aircraft & Commercial Enterprises strives for excellence in every aspect of business. As a result, we have achieved several certifications.
