The main expense categories
Owning a light aircraft involves a budget that goes well beyond the purchase price alone. Beyond mandatory maintenance, you need to factor in insurance, parking, fuel and a reserve for major upcoming costs (engine overhaul, avionics). The rule of thumb most often quoted in the industry is to budget between 8% and 15% of the aircraft's purchase value every year, excluding flight hours.
Maintenance and mandatory inspections
The annual inspection (mandatory to maintain airworthiness) is the most predictable expense: generally budget between €800 and €2,500 for a light single-engine aircraft depending on the workshop and the condition of the aircraft, excluding spare parts if defects are found.
- Annual inspection (100h/annual) — €800 to €2,500 depending on the aircraft and the approved workshop.
- Engine overhaul reserve (TBO) — to be spread over the remaining hours before overhaul: budget €15,000 to €40,000 for a complete overhaul depending on the engine, divided by the hours remaining until due.
- Consumables and small parts — tires, filters, spark plugs, battery: €300 to €800 per year with regular use.
- Avionics and instruments — GPS database updates, calibrations: €100 to €400 per year.
Fixed costs: hangar and insurance
These two items are due whether the aircraft flies or not, and vary significantly depending on the region and the type of coverage chosen.
| Item | Annual range |
|---|---|
| Enclosed hangar | €1,500 to €4,000 |
| Outdoor parking spot | €400 to €1,200 |
| Liability + hull insurance | €1,000 to €3,500 depending on the insured value and the pilot's experience |
| Flying club membership (if club-based) | €150 to €500 |
Variable costs: fuel and flight hours
Fuel remains the variable most dependent on your actual usage. A piston single-engine aircraft consumes on average between 25 and 40 liters/hour; at the price of avgas in Europe (often €2.20 to €2.80/L in 2026), one flight hour therefore represents €60 to €110 in fuel alone, on top of landing and parking fees at stopovers.
Indicative annual budget by aircraft type
These estimates cover maintenance, insurance and hangar for moderate private use (50 to 100 hours/year), excluding fuel and excluding the engine overhaul reserve.
| Aircraft type | Indicative annual budget |
|---|---|
| Microlight | €2,000 to €4,000 |
| Light single-engine (e.g. Cessna 172, Piper PA-28) | €5,000 to €9,000 |
| High-performance single-engine (e.g. Cirrus SR22) | €9,000 to €16,000 |
| Light twin-engine | €15,000 to €30,000 |
| Turboprop | €40,000 and up |
How to keep your budget under control
Co-ownership (sharing the aircraft between several pilots) remains the most effective way to reduce your individual budget while flying an aircraft more capable than you could afford alone. Choosing a maintenance workshop away from major airport hubs (often more expensive) and setting aside a monthly reserve for major upcoming costs also help avoid cash-flow surprises.
