Aircraft Appraisal

Welcome to U.S Aircraft Appraisal, LLC customers!  USAA has recently combined operations with Guy Lieser Aviation LLC. This will allow us to provide a broader range of aviation services to you. We look forward to serving your valuation needs in the future.


As you may already know, the National Aircraft Appraisers Association (NAAA) was officially retired at the end of 2018. We've enjoyed our professional and personal relationship with this outstanding organization since 2002. We want to thank Mr. Brian Jacobson for his leadership, guidance and dedication to NAAA over the years. Brian is a true professional and we wish him and his family a long, healthy, and happy retirement!


Moving forward, GLA is pleased to announce its affiliation with the Professional Aircraft Appraisal Organization (PAAO). We've received our professional designation as Senior Certified Appraiser (PSCA) and, without interruption, we continue to provide quality aircraft appraisal services to our clients. So, thank you for being a valued client and we look forward to serving your aircraft appraisal need in the future. Enjoy our new website and feel free to connect with us via email, website, or by phone at 630-815-5499.
