Two-seat composite primary trainer · Single-engine piston aircraft · production 1998–present · See its reach on the 3D globe
A Diamond DA20-C1 costs approximately $347k (€321k) to $415k (€384k) to buy at 2025 market values, and about $27k (€25k) a year to own flying 80 hours, roughly $340 (€315) per flight hour all-in. It seats 2, cruises at 130 kt (150 mph) and has a published range of 532 nm (985 km), needing about 1,640 ft (500 m) of runway. Figures are indicative planning estimates compiled 2026-07, not a quote for any specific airframe.
The DA20-C1 Eclipse is a two-seat composite trainer with a bubble canopy, sweet handling and a Continental IO-240 that sips fuel, a favourite of academies that want low operating costs and students who enjoy flying it. It is efficient and genuinely fun. What it is not is a travelling aeroplane: two seats, minimal baggage and no meaningful instrument-weather flexibility keep it firmly in the training and local-flying role. As a first owned aircraft for a cost-focused pilot it is hard to beat; as a family machine it is the wrong tool.
The Diamond DA20 Katana is a sleek, two-seat composite aircraft built specifically to dominate commercial flight training. It uses a reliable 125 hp Continental IO-240 for excellent fuel economy, cruises at a modest 122 kt and reaches a maximum range near 703 nm. The cockpit is surprisingly comfortable and ergonomic, with four-point harnesses and a canopy that gives near fighter-jet visibility.
The two-seat cabin, baggage provision and fuel capacity set a deliberately narrow mission. Use the actual loading and approved equipment list before planning longer training sectors. Canopy and composite condition, engine status, avionics and local Diamond support matter at pre-buy. Buyers seeking serious family travel or a broadly equipped instrument platform may outgrow the design even if its headline range covers the route.
Flight schools wanting a rugged, highly economical, spin-resistant trainer, or private pilots who fly local fair-weather hops for fun.
Pilots who want a long-distance, all-weather travel machine, or anyone needing to carry more than one passenger and a flight bag.

Efficient and pleasant to fly, but two seats, limited baggage and no instrument-weather flexibility constrain travel missions.
Indicative cash costs at 2025 market values, before financing, depreciation and tax. The fixed base is the same whether the aircraft flies or not, so the effective hourly cost falls as utilisation rises.
| Annual use | Annual cash cost | Effective cost / h | Five-year cash outlay |
|---|---|---|---|
| 40 h / year | $22k (€21k) | $556 (€515) | $488k (€452k) |
| 80 h / year | $27k (€25k) | $340 (€315) | $513k (€475k) |
| 120 h / year | $32k (€30k) | $268 (€248) | $538k (€498k) |
| 180 h / year | $40k (€37k) | $220 (€204) | $575k (€533k) |
Every figure above is built from a $17k (€16k) fixed annual base, covering hangarage, insurance, scheduled maintenance reserves and recurring airworthiness costs, plus $124 (€115) per hour flown for fuel, reserves and consumables. It is a planning model for comparing aircraft and testing utilisation, not a maintenance programme quote, insurance quote or pre-buy assessment.
Older examples add calendar-driven maintenance: a 2011-built airframe is estimated at $33k (€31k) per year at 80 hours. Airframe and engine time, maintenance and damage history, avionics, equipment, geography and tax treatment move a real transaction further than the model year does, so price the aircraft in front of you, not the model. A cheaper example carrying deferred maintenance can be the more expensive aircraft once the first annual inspection is complete.
Diamond DA20-C1 cost guide answers the same figures as standalone purchase and ownership questions, and the ownership cost calculator lets you replace these assumptions with your own hours and fixed costs.
Nothing beyond a pilot certificate for the category and class. With fixed tricycle gear and no endorsement requirement of its own, this is among the simplest certified aircraft to qualify in, which is a real part of why it is cheap to insure and easy to check out in.

An indicative 2025 market price for a Diamond DA20-C1 is $347k (€321k) to $415k (€384k). This is a planning estimate normalised across the market, not a quote for a specific airframe. Condition, engine time remaining, avionics and damage history move the real number more than the model year does.
Flying 80 hours a year, a Diamond DA20-C1 works out at roughly $27k (€25k) annually, which is about $340 (€315) per flight hour all-in once fixed costs are spread across those hours. The direct cost per hour alone, covering fuel, reserves and consumables, is about $124 (€115).
Published range is 532 nm (985 km). With 2 people aboard and realistic reserves, plan on a practical radius of about 383 nm rather than the brochure figure.
Plan on approximately 1,640 ft (500 m) for take-off. Check this against the actual runway, surface, slope, temperature and loading, all of which extend the requirement.
Direct comparisons against the models buyers most often weigh against this one.
