Aircraft overview

The Diamond DA20 / DV20 Katana is a two-seat, single-engine light aircraft developed by Diamond Aircraft as a composite primary trainer and personal aircraft. The Austrian-built DV20 Katana entered production in the early 1990s, followed by the Canadian-built DA20 series for North American and export markets. It is a low-wing aircraft with fixed tricycle landing gear, a T-tail, side-by-side seating and a clear bubble canopy. Its significance in the used market comes from its role as a durable flight school aircraft that also appeals to private owners seeking simple handling, low fuel burn and modern composite construction.

Performance & specifications

Typical cruise performance is about 115 to 125 knots, depending on variant, engine, propeller and operating weight. Published range is commonly around 500 nautical miles for DA20-C1 models under suitable conditions. Useful load is generally in the mid-500 lb range, making weight and fuel planning important when carrying two adults. Service ceiling is typically listed at about 13,000 feet. Powerplants differ by variant: the DV20 and DA20-A1 Katana use Rotax 912 series engines, while the DA20-C1 Eclipse and related C1 models use the 125 hp Continental IO-240-B. Most aircraft have fixed-pitch propellers, with some market and model differences.

Cabin & avionics

The cabin seats two occupants under a large forward-hinged canopy, with excellent outward visibility and center control sticks. The cockpit is relatively narrow compared with four-seat touring aircraft, but it is efficient for training, local flying and time building. Baggage capacity is modest. Many aircraft are VFR equipped, reflecting their training role. Typical avionics include conventional six-pack instruments, Garmin or BendixKing radios, transponders and GPS units such as the Garmin GNS 430 or later panel upgrades. The DA20 / DV20 Katana is not commonly associated with factory Garmin G1000 or Garmin Perspective installations, which are more typical of other Diamond or Cirrus models.

Buying & value

Buyers should evaluate airframe hours, flight school history, composite condition, canopy condition, landing gear wear, engine time and compliance with Diamond service bulletins and applicable airworthiness directives. Rotax-powered DV20 and DA20-A1 aircraft can offer low operating costs, while Continental-powered DA20-C1 aircraft are common in North America and often preferred where conventional aircraft engine support is valued. Upgrades to look for include modern GPS, ADS-B equipment, updated radios, improved interiors and engine or propeller refreshes. On PlaneFox listings, current asking prices average about EUR 113,000, with a broad range from about EUR 25,000 to EUR 232,000, reflecting age, variant, hours, avionics and overall condition.
