While the rest of the world seems intent on growth through mergers, Covington Aircraft remains true to the power of one: you. By providing uncompromising service with old-fashioned values, we have built Covington Aircraft over the last 50 years, one customer at a time.

Covington Aircraft

Founded in 1972, Covington Aircraft Engines is one of the world’s leading aircraft engine maintenance, repair and overhaul facilities specializing in the Pratt & Whitney PT6A turbine, and R-985 and R-1340 radial, engines. We are a Pratt & Whitney Canada certified Distributor and Designated Overhaul Facility (DDOF), and provide world-class engine support to corporate, agricultural, and government aircraft.
In addition to engine maintenance services, we perform engine installations, operate state-of-the-art engine testing facilities, and maintain a complete inventory of engine parts and accessories. We’re centrally located in Okmulgee, Oklahoma in the United States near Tulsa, Oklahoma and Tulsa International Airport (TUL). We also have the advantage of utilizing Okmulgee Regional Airport (OKM), which is adjacent to our facility.
Covington performs all stages of engine repair and overhaul work in-house. We conduct Non-Destructive Testing (NDT) to verify the integrity of critical parts prior to use, and use computer-controlled machinery for necessary machining, grinding, and balancing prior to assembly. An on-site Quality Control inspector oversees every step of the overhaul process, and when a rebuild is complete, the engine testing and run-in is performed at our own engine testing facilities to verify the highest quality rebuild possible.

Our Core Values

Integrity is the most important element in our business model, and the principle on which Covington Aircraft Engines was founded. We pride ourselves in earning our customers’ trust and commit our efforts to keeping it each day.

Dependability is critical because valuable business dollars and the hard-earned livelihoods of our clients demand reliability. Every engine that comes into our shop receives our highest level of attention and service, which ensures the quality and timeliness our customers expect.

Affordability is key to providing a trusted basis for a relationship. We know what other overhaul facilities charge, and our prices are not always the lowest. However, we strive to ensure only the most cost-effective work is performed and offer a variety of options to customers to ensure service that fits their needs and their budgets. Not just because

Quality Service through our unparalleled ability to provide personal attention to every customer has earned us distinct honors, and the honor of serving many lifelong customers. We believe that if you view customers as family, you’ll serve them well – and that’s exactly what we do.


As a family-owned company, we think of our employees as a part of our extended family. We are proud of our employees, and they are the driving force behind our success.

Our ethics

When Paul and Betty Abbott took over Covington Aircraft Engines nearly 50 years ago, they followed in the previous owner’s footsteps by dedicating this business and the influences it would have to the Lord.
