Certified Aircraft Appraisal and Valuation Services

What is an Aircraft Appraisal?

An aircraft appraisal is an unbiased opinion of the value of your aircraft and its current condition.

Similar to a home appraisal, an aircraft appraisal helps you answer the question, "How much is my jet worth?" This is essential information in order to sell, insure or properly account for your jet.

Put simply, our Certified Aircraft Appraisal Service helps you:

  • Evaluate your aircraft and its characteristics.
  • Understand the current pre-owned aircraft market.
  • Understand the physeical characteristics and condition of your aircraft.
  • Locate all accompanying maintenance records.
