USAA's Chief Appraiser is Mr. Guy Lieser, a Senior Certified Appraiser credentialed by the National Aircraft Appraisers Association (NAAA)NAAA is a global organization who's members are aviation industry experts. Their reports are considered to be the gold standard for aircraft appraisals worldwide. Mr. Lieser has been a member in good standing since 2002. 


It takes a knowledgeable expert to write an accurate aircraft appraisal report. Every appraisal written by USAA begins with a physical examination of the subject aircraft and its records.  Each component of value on the aircraft is independently analyzed for its condition. This includes the airframe, engine(s), propeller(s), avionics, interior and paint condition, calendar and hour limited components, logbook inventory, deicing equipment, and aircraft modifications.  In some instances, deductions are taken for poor condition, past due maintenance, recent or current damage, and/or missing aircraft records.  After a thorough analysis, the aircraft's components of value are added together, deductions are subtracted, and an opinion of value is generated that is credible and accurate. NAAA certified appraisal reports are accepted by lending institutions around the globe.


As chief appraiser, Mr. Lieser has appraised or evaluated more than a thousand aircraft worldwide.  His experience includes opinions of value for all makes and models of piston, turboporp and jet aircraft, including fixed wing, helicopters, experimentals, homebuilts, warbirds and seaplanes.  His client list includes private individuals, corporations, insurers, manufacturers, lenders, law firms and government agencies.
