The only way to determine the correct value of your aircraft is to have it appraised. USAA provides reliable, and accurate appraisal solutions for the things you buy, fly and sell. 


USAA's Chief Appraiser, Guy Lieser, is a Senior Certified Appraiser credentialed by the National Aircraft Appraisers Association (NAAA)NAAA is a global organization who's members are aviation industry experts.

Services include the establishment of current market value, retrospective market value, orderly liquidation value, and future value of an aircraft after proposed modification, and diminution of value based upon usage or damage.


At USAA, every appraisal assignment begins with a physical examination of the subject aircraft and its records. Each component of value on an aircraft is independently analyzed for it's condition. This includes the airframe, engines, propellers, avionics, interior and paint condition, calendar and hour limited components, deicing components, and aircraft modifications.  When indicated, deductions are taken for poor condition, past due maintenance, recent or current damage, and/or missing aircraft records. Then the aircraft's components of value are added together, the deductions are subtracted, and an opinion of value is generated that is accurate and credible. The final report you receive is an NAAA Certified Aircraft Appraisal, written by an industry expert, and accepted by institutions around the world.


Mr. Lieser has appraised or evaluated more than a thousand aircraft worldwide.
