Damage History & Diminution of Value

Aircraft damage history can affect value primarily through market perception, liquidity, and buyer resistance, rather than repair cost alone. Proper valuation requires analysis of how the market actually reacts to specific damage events within a given aircraft category.

AircraftAppraisals.aero provides market-based damage history analysis as part of independent aircraft appraisals prepared for bank, legal, and fiduciary reliance, in compliance with the Uniform Standards of Professional Appraisal Practice (USPAP).

Damage history analysis is performed to determine whether, and to what extent, a prior event impacts:

• Fair market value
• Collateral risk
• Marketability and buyer depth
• Time-to-sale expectations

Not all damage events result in a measurable diminution of value. Each case must be evaluated independently.

When damage history exists, analysis is based on the following factors:

• Nature and extent of the event
• Quality and completeness of repair documentation
• Repair facility credentials and conformity
• Post-repair configuration and airworthiness
• Disclosure history and buyer awareness
• Observed market reaction within the applicable aircraft segment

Adjustments are supported by documented market evidence, not fixed formulas or generalized percentage discounts.

The primary valuation impact of damage history is often reflected in:

• Reduced buyer pool
• Increased marketing time
• Pricing pressure during negotiation
• Greater sensitivity to maintenance status and inspections

Liquidity considerations are particularly relevant for bank collateral evaluation, where remarketing risk must be assessed conservatively.

Damage history analysis does not assume:

• Automatic value penalties
• Uniform impact across aircraft types
• Equivalence between repair cost and value loss
• That all damage is fully mitigated by the repair

Market behavior varies significantly by aircraft category, age, use case, and buyer profile.

Damage history analysis is most commonly applied within appraisal assignments prepared for:

• Bank financing and collateral review
• Estate, trust, divorce, and litigation matters
• IRS-compliant aircraft donation appraisals

In each context, the analysis is tailored to the intended use and intended users of the appraisal.

Market reaction to damage history may vary by region depending on buyer concentration, availability of comparable aircraft, and regional demand.

We perform on-site aircraft inspections throughout California, including Southern California, and support appraisal assignments nationwide when damage history analysis is required.

Each damage history analysis is conducted independently, with conclusions supported by market evidence and professional judgment appropriate to the intended use of the appraisal.

Damage history is evaluated as part of a broader valuation framework, not in isolation, to ensure conclusions are defensible under lender, legal, and fiduciary scrutiny.
