Diminished value is one of the most overlooked challenges in aircraft underwriting and claims. Even when an aircraft is fully repaired and airworthy, accident history or documentation gaps can significantly reduce its fair market value.
Here are the issues that most often affect value:
- Accident or incident history – Market perception alone can lower resale value.
- Missing or incomplete logbooks – These create uncertainty and often lead to major valuation reductions.
- Undocumented repairs or modifications – STCs, structural work, or changes without proper records raise red flags.
- Repair quality concerns – Not all repairs are treated equally by the market.
Because every situation is different, diminished value requires careful review of records, repair documentation, and comparable market behavior.
