What Is an NAAA Aircraft Appraisal?


Appraisal: The act or process of developing an opinion of value; or an opinion of value*

Value: An opinion in monetary terms of the worth of real or personal property (not necessarily the same as price or cost)

Price: The amount asked, offered, or paid for a property*

An appraisal is an opinion of value. It is written by a person who has the knowledge, expertise, and credibility to determine the value of the subject aircraft. The process of developing an appraisal is intricate. It is not, as most people assume, the act of looking up a value in a book or in a computer program.

Improper evaluations of aircraft by persons who are not qualified to make them, or by those who have their own agenda in pricing the subject aircraft, lead to trouble for unsuspecting buyers. High values are far more common than low values. Whether you are a buyer, seller, banker, or insurance company executive, you have a major stake in ensuring that the amount paid for the aircraft is reasonable.

You will only know that a valuation is reasonable if an independent, objective third party examines the aircraft and its records.

The appraisal is an impartial, professional opinion as to the value of the particular aircraft being examined. However, it is much more than that. A professional appraisal is a thorough description and inventory of the aircraft that verifies the major selling points for the buyer and financing entity.

Never should a salesman's written 'appraisal' be considered valid. A salesperson cannot write an opinion of value on an aircraft he or she is selling. It is a direct conflict of interest.

As part of the purchase process, the buyer needs to engage a member of the National Aircraft Appraisers Association to determine the value of the subject aircraft. That should be done early in the process before any negotiations take place regarding the price of the aircraft. Too often, buyers wait too long to contact the appraiser only to find that the price they have agreed to in a written contract to purchase is too high.

Others wait until after they have purchased their airplane when a banker or insurance agent will not agree to the requested value. They hire an NAAA member only to have their elation at making the purchase turn to frustration when they find that the value of the aircraft was not what they expected.

An NAAA Certified Aircraft Appraiser will write a report that will assist in expediting the sale of the aircraft because the buyer and seller know the market value and relative condition of the aircraft through the independent appraisal. Information is knowledge, and that is what you get in an aircraft appraisal written by Over The Top Aviation LLC’s Jeff Soules, an NAAA senior appraiser.

A report written by an NAAA Senior appraiser is a great selling tool because it gives a potential buyer a solid "feel" for the aircraft in the words of the objective appraiser. After reading the appraiser's report, the potential buyer will have more confidence in the condition and appearance of the airplane than he would another airplane where all that is available is the owner's description.

This is a plus for the seller who will find a buyer who is confident in the aircraft will be easier to make a deal with. When a report written by an NAAA Certified Aircraft Appraiser is presented to a banker for financing the banker will find that it supports the bank's collateral position in the aircraft loan by verifying that the aircraft is what it is said to be.

In the past too many bankers who have done self-evaluations without any manner of verifying the collateral exists, or that the aircraft is equipped as represented, wound up putting their bank at risk for a major loss had their client defaulted. There is absolutely no reason to accept a risk of that magnitude when there is an NAAA Certified Aircraft Appraisers right here available to you who can detail the value and general condition of the aircraft.


A report written by Over The Top Aviation LLC is an impartial opinion of the value of an aircraft, prepared by experts who know all the factors which make up the current behavior of the used aircraft market.

It is an opinion of value based on experience and repeated analysis of these factors. It is an opinion of value, which can be substantiated and justified. It is an opinion of value made by a certified, recognized, professional aircraft appraiser.

A professional aircraft appraiser must acquire all the facts about the aircraft in question. The appraiser thoroughly examines the aircraft logbooks, inspects the exterior and interior surfaces of the aircraft, and pays close attention to the general condition as well as the maintenance history of the aircraft.

One of the tools the appraiser uses is the NAAA's extensive computer-based system that assists the appraiser in producing accurate and prompt aircraft appraisals.
