It takes a knowledgeable expert to write an accurate aircraft appraisal report. Every appraisal assignment begins with a physical examination of the subject aircraft and its records. The components of value on each aircraft are independently analyzed for their 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 report you receive is an NAAA Certified Aircraft Appraisal, written by an industry expert, and accepted by institutions around the globe.


Mr. Lieser has appraised or evaluated more than a thousand aircraft worldwide. He is  competent in all makes and models of piston, turboporp and jet aircraft; including fixed wing, helicopters, experimentals, homebuilts, warbirds and seaplanes.
