In the competitive world of aviation, trust, credibility, and precision are non-negotiable. For businesses and individuals seeking accurate aircraft appraisals, buying or selling aircraft, or simply managing their aviation assets, the right partner can make all the difference. Enter OakTree Aviation Services (OTAS), a California-based company that has earned a stellar reputation for delivering credible, fair, and meticulous evaluations of a wide range of aircraft, from vintage airplanes to the latest business jets.

Headquartered in Central and Southern California, OakTree Aviation Services operates from its offices in Exeter and Burbank. But their reach extends far beyond the borders of the Golden State, with a global presence that ensures quick deployment of their resources to clients no matter their location. Whether it's Oregon, Nevada, Europe, South America, or Asia, OTAS is ready to serve aviation enthusiasts, business owners, and corporations worldwide. At the helm of OakTree Aviation Services is Rick Rossner, President, Director, and Senior Appraiser. With over 30 years of professional flying experience, Rossner is not just an appraiser — he’s an aviator with deep-rooted knowledge and experience in aviation, which is essential for assessing the intricate details of various aircraft types. From piston-engine planes to turbo-props, pure jets, experimental, and even warbird aircraft, Rossner’s expertise extends across fixed-wing and rotor-wing crafts alike.

His credentials are equally impressive. Rossner is a Senior Associate of the Professional Aircraft Appraisers Organization (PAAO), a title earned through years of rigorous training, testing, and certification. His qualifications, combined with hands-on experience, make OTAS the trusted choice for discerning clients seeking reliable aircraft appraisals.

Client-Centered Service: The Core of OakTree’s Mission

At its heart, OakTree Aviation Services is a client-focused aviation support and consulting business. As Rick Rossner and his team often emphasize, "Taking care of you is our priority!" This commitment to customer care is reflected in their mission — to offer credible and first-class customer service and support, ensuring that each client walks away with complete confidence in the evaluation process.

For OTAS, appraising aircraft is not just about crunching numbers or generating reports. It’s about forming relationships built on trust. When clients entrust OTAS to represent them in aircraft transactions, they can rest assured knowing that the company is dedicated to negotiating the best possible deals, whether they are buying or selling.

Precision and Credibility: The USPAP-Compliant Approach

What truly sets OakTree Aviation Services apart is their adherence to the Uniform Standards of Professional Appraisal Practice (USPAP). USPAP is the gold standard in appraisals, ensuring that evaluations meet the highest ethical and performance standards in the industry.

USPAP guidelines require appraisers to demonstrate extensive knowledge, skill, and ethical judgment when conducting appraisals. As a USPAP-compliant service provider, OTAS ensures that their aircraft appraisals are accurate, transparent, and reflect real-time market results. From the U.S. to South America, Europe, and Asia, OTAS has earned a reputation for providing USPAP-compliant aircraft appraisals that clients can rely on with confidence.

The process of a USPAP-compliant appraisal begins with a thorough examination of the aircraft, including its exterior, interior, avionics, airframe, and engine. OTAS pays close attention to any modifications, signs of damage, and the condition of components like propellers, flight instruments, and deicing systems. All records, including logbooks and maintenance paperwork, are scrutinized to ensure that the aircraft’s history is thoroughly documented.

By adhering to strict standards, OTAS ensures that their appraisals are court-admissible, bank-accepted, and in line with the highest international appraisal standards.

Going Global: Serving Clients Worldwide

While OakTree Aviation Services has its roots in California, its influence and services extend across the globe. With offices in Exeter and Burbank, OTAS regularly serves clients across Northern, Central, and Southern California, as well as Oregon, Washington, Idaho, Nevada, and Arizona. However, their reach doesn't stop at the borders of the U.S. — OTAS frequently deploys resources to clients in Europe, Asia, and South America, providing global support wherever it's needed.

This ability to quickly mobilize resources and expertise makes OTAS the go-to solution for aircraft appraisals and acquisitions, no matter where their clients are located.
