USPAP stands for Uniform Standards of Professional Appraisal Practice. A USPAP-compliant appraisal meets strict industry standards for ethics, accuracy, and methodology.

A full appraisal includes an on-site inspection of the aircraft, while a desktop appraisal is done remotely using documents and data provided by the client.

Will your valuation affect my aircraft’s resale value?

It depends on the service. Desktop appraisals are usually completed within 3–5 days, while full on-site appraisals may take 7–10 days including travel and report preparation.

Yes. We provide damage assessments and retrospective valuations, even for older or previously repaired aircraft, using detailed records and market data.

Dan is always precise about the data he presents whether it has to do with an aircraft specification or market analysis. He clearly understands how a slight deviation in an equipment list or maintenance status of an aircraft can influence its assessed value. In my dealings with Dan I have found he takes great care in representations of the aircraft he is either valuing or assisting in the sale of. Dan has a comprehensive knowledge of aircraft, in particular the Textron product line, and is able to clearly articulate the challenges and advantages of the asset he is tasked with evaluating.
