About Cornerstone Aircraft Sales

Thank you for visiting Cornerstone Aircraft Sales.

Buying or selling an aircraft is a significant decision. Our mission is to make the process clear, secure, and straightforward from start to finish. This business is built on trust, and every transaction is guided by transparency, integrity, and a safety-first mindset.

Whether you are exploring your options or preparing to move forward, you can expect honest guidance, clear communication, and professional support without pressure.

Your Aviation Home Base

Cornerstone Aircraft Sales proudly operates from Galt Airport (10C), located in the heart of McHenry County.

10C sits within an hour radius of many of Chicago’s most populated suburbs, offering convenient access while avoiding congestion, delays, and operating costs associated with larger metropolitan airports.

The airport is home to JB Aviation Flight School , which has earned multiple AOPA Flight Training Experience Awards, reflecting a culture of safety, professionalism, and instructional excellence.

Through strong relationships within the airport community, we support clients far beyond aircraft transactions.

Driven by Leadership, Backed by Experience

Cornerstone Aircraft Sales is supported by more than 25 years of combined aviation experience through the team that helps operate Cornerstone and the experienced professionals throughout our airport community.

This network brings practical knowledge, trusted relationships, and hands-on experience across multiple areas of aviation.

• Aircraft sales and acquisitions
• Airport management and operations
• JB Aviation Maintenance and technical services
• JB Aviation Flight School for flight training and pilot development

Expert Guidance. Strong Results.

Successfully buying or selling an aircraft requires more than advertising and negotiation. It requires accurate valuation, timing, and real market insight.

Cornerstone Aircraft Sales operates as more than a brokerage. We serve as a centralized aviation resource designed to simplify aircraft ownership and support every phase of your journey.

• Direct coordination with JB Aviation Maintenance for maintenance and pre-purchase inspections
• Communication with airport management for hangar space and storage solutions
• Connections with JB Aviation Flight School for training, ratings, and proficiency

Our clients work directly with one dedicated point of contact throughout the entire process — no hand-offs, no hoops, and no confusion.
