About the Evektor EV-55 Outback

The Evektor EV-55 Outback is a Czech-built light twin turboprop designed for utility missions in austere environments. First flown in 2011 and certified under FAR Part 23, the Outback was conceived as a rugged, unpressurized workhorse capable of operating from short, unpaved strips, hence the name. Powered by two Pratt & Whitney Canada PT6A-21 engines producing 500 shaft horsepower each, the aircraft seats up to nine passengers or can be configured for cargo, medevac, or surveillance roles.

Its high-wing design, fixed tricycle landing gear, and large cargo door make it well-suited for bush operations, skydiving, and regional freight. The EV-55 cruises at around 190 knots and has a range of approximately 800 nautical miles, positioning it as a modern alternative to aging Cessna Caravans and Twin Otters in niche markets. While production has been limited and the type remains relatively rare in North American skies, it has found favor with operators seeking a versatile, economical twin for specialized missions.

SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
