Starting from comparable listings
The most reliable method for valuing the resale price of a used aircraft is to compare genuinely similar aircraft: the same model, close year, comparable total hours, and above all a similar remaining engine potential. A price shown in a listing is only a starting point: it reflects the seller's expectations, not necessarily the final transaction price. Cross-reference several active listings and, where possible, recently completed sales to arrive at a realistic range rather than a single figure.
The differences between two examples of the same model and the same year can easily reach 20 to 30% depending on engine condition, installed avionics and maintenance history. A serious valuation therefore always starts with a range, then refined using the detailed criteria below.
Remaining engine and airframe potential
The potential remaining before the next major engine overhaul (TBO) is one of the most decisive factors in the price. An aircraft close to its potential limit will mechanically lose value, as the buyer will need to budget for an overhaul in the short term. Conversely, a recently overhauled engine (or one with significant remaining potential) justifies a premium over comparable aircraft on the market.
| Factor | Impact on value |
|---|---|
| Engine close to TBO | Discount, overhaul cost to be anticipated by the buyer |
| Recently overhauled engine | Premium, strong selling point |
| Airframe with low total hours | Premium, especially on popular models |
| Corrosion or repaired damage | Discount, depending on the nature and quality of the repair |
Maintenance history and documentation
A complete logbook, filed maintenance invoices and clear traceability of work carried out reassure the buyer and support the price. Conversely, an incomplete history or grey areas (undocumented changes of owner, gaps in record-keeping) almost always lead to downward negotiation, even if the aircraft is genuinely in good condition.
- Complete and consistent airframe logbook and engine logbook.
- Invoices for periodic inspections (Part-M / Part-ML) kept on file.
- Up-to-date certificate of airworthiness with no particular restriction.
Avionics and equipment
Modern avionics (certified GPS, ADS-B Out transponder, autopilot) have a real impact on value, particularly where regulations require this equipment for certain types of airspace. An older, minimally equipped aircraft will require an immediate investment from the buyer, which is directly reflected in the negotiated price.
General condition, paint and interior
Cosmetic condition (paint, interior, upholstery) mainly influences how quickly an aircraft sells and the initial impression, more than the technical price. A well-presented aircraft sells faster and limits aggressive negotiation, but should not mask poor remaining engine potential or a patchy maintenance history to an informed buyer.
Location and local market
Value can vary by country and geographic area: availability of parts, local maintenance network, regional demand for a given aircraft type. A model that is highly sought after in one country can sell for less elsewhere, due to an insufficient number of local buyers. Broadening the reach of the listing across Europe often makes it possible to obtain a valuation — and a final price — closer to the real market value.
Common overvaluation mistakes
Sellers frequently overvalue their aircraft based on the original purchase price, on personal work not valued by the market, or on a single, poorly chosen competing listing used as a benchmark. A realistic valuation always relies on several recent comparables, weighted by remaining engine potential and maintenance history, rather than on sentimental attachment or past investment that does not automatically translate into a capital gain.
