When buying, selling, financing, or insuring an aircraft, the appraisal is one of the most important tools you’ll rely on. A credible appraisal provides an objective opinion of value based on the aircraft’s condition, equipment, and current market data. But for an appraisal to be truly useful, it must also be ethical and free of conflicts of interest.
Why Ethics Matter
An aircraft appraisal isn’t just a number on paper—it directly influences loan approvals, insurance coverage, tax reporting, and even legal disputes. If the appraisal is biased or manipulated, the ripple effects can be costly: lenders may overextend credit, insurers may underwrite incorrect coverage, or a buyer may end up paying too much. Ethics ensure the appraisal is fair, transparent, and defendable if ever questioned.
Where Conflicts of Interest Show Up
Conflicts of interest in aircraft appraisals are more common than many realize. A few real-world examples include:
-
Seller vs. Buyer Pressure – A seller may want a higher number to justify their asking price, while a buyer may want it lower to negotiate. If the appraiser feels pressured to “pick a side,” the result isn’t truly independent.
-
Appraiser with a Stake – If the appraiser also has a financial interest in the aircraft—say, through ownership, brokerage, or a referral fee—their opinion can’t be considered impartial.
-
Dual Roles – Sometimes, an appraiser may also act as a mechanic, broker, or consultant for the same aircraft. While not always wrong, this creates a blurred line that should be disclosed.
-
Lack of Experience – Taking on an appraisal for an aircraft outside the appraiser’s knowledge (for example, a turbine jet when they’ve only worked on piston singles) can unintentionally mislead a client.
How to Protect Against Conflicts
The good news is that conflicts of interest can be managed or avoided altogether with the right practices:
-
Ask for Disclosure Up Front – A reputable appraiser will disclose any prior involvement with the aircraft or parties.
-
Engagement Letters – A written agreement that outlines who the client is, what the report will be used for, and the scope of the appraisal prevents surprises.
-
Check for Professional Standards – Many appraisers follow USPAP (Uniform Standards of Professional Appraisal Practice) or belong to organizations like ASA or ISTAT that hold them to a code of ethics.
-
Walk Away if Needed – A trustworthy appraiser will turn down work if the conflict can’t be managed fairly.
Why It Matters to You
If you’re a buyer, seller, lender, or insurer, you need to be confident that the number in the appraisal reflects reality—not someone else’s agenda. Asking the right questions, choosing a qualified appraiser, and insisting on transparency protects your financial interest and ensures smoother transactions.
Bottom Line
Ethics and independence are just as important as technical knowledge in aircraft appraisals. A truly valuable appraisal is one that stands on its own, backed by data, and free from bias. In a market where millions of dollars can ride on a single valuation, making sure your appraiser follows ethical standards is one of the smartest steps you can take.
