About Airplane Intel

Airplane Intel LLC is based on Orlando, FL, though we work with aircraft owners, operators, and prospective buyers throughout the United States and around the world. Originally formed as The Prebuy Guys, specializing in aircraft pre-purchase inspections and acquisition consulting, we have expanded to a complete aircraft ownership firm that goes well beyond the purchase.

Today we are your one-stop-solution for aircraft ownership. We can help you with our holistic approach to aircraft ownership from planning the purchase and pre-purchase inspection, to post-purchase support, aircraft management management, and the sale of your turbine aircraft. We are a team of professional pilots, technicians, inspectors, aviation legal and tax experts with over 60 years' working in the field to help you make safer and smarter decisions with your personal or business aircraft. While we work with all makes and models, we specialize in turbine Cessna aircraft such as the Cessna Citations, Denali, and Caravan.

Our proven strategies and unique perspective help to simplify the process of aircraft ownership and streamline phases of the transaction. We will help you maximize your investment, increase safety, reduce risk, and save money.

Notable industry Achievements

2016: We created the first aviation podcast about aircraft ownership called the Airplane Intel Podcast. We cover a wide range of topics for aircraft owners and prospective buyers including aircraft comparisons, maintenance tips, management strategies, and interviews with owners and industry experts.

2017: We have been able to leverage enhancements in technology to bring more options to our clients. In many cases, the prospective buyer lives hundreds or thousands of miles away from candidate aircraft. Just looking at an airplane becomes quite time consuming an expensive. As a result, we introduced a live stream video conference evaluation that we call a Virtual Prebuy. A virtual prebuy allows prospective buyers (and their team) to get a detailed look at an airplane without the time, cost, and hassle of traveling or sending us to the aircraft. In many cases, a virtual prebuy can supplement or be a substitute for an on-site pre-purchase inspection.

2018: We launched our latest program called Aircraft Sales Systems, a turnkey approach to selling your airplane. Given our unique perspectives in the minds of buyers, we know how to structure an aircraft transaction to best serve both parties. The buyer know they are getting a safe, legal, and compliant aircraft and the seller knows they will sell their aircraft faster and for the best price.

2018: We formed the industry’s first network of Independent Aviation Field Agents to help us serve more customers worldwide. Our field agents help to facilitate virtual prebuys and sales demos to help bring prospective buyers and sellers together on qualified aircraft. Many of our field agents are pilots, A&P’s and/or aircraft owners. To date, we have 200 agents across the United States and several countries in Europe, Asia, and South America.
