Evektor EV-55 Outback
|EV-55 prototype (2011)|
|Role||Twin-engined utility aircraft|
|National origin||Czech Republic|
|First flight||24 June 2011|
|Number built||2 + 1 for static testing|
In 2004 the company announced its plan to design and construct a two-engined utility aircraft that would carry up to 14 passengers or 4000 lb (1800 kg) of cargo, and operate from unimproved fields and at high-altitude airports.
The first prototype, an EV-55M (military version), flew from Kunovice Airport in June 2011, with company pilot Josef Charvat and military pilot Maj. Jiri Hana at the controls. It was estimated at $2.1 to $2.2 million in 2012. The first production-conforming aircraft flew from Kunovice in April 2016.
In June 2016, its price was $3 million and two aircraft should finish development flights with 200 hours in 2016, for 500 total hours. Evektor secured enough investment to complete the certification process scheduled for 2017, with a minority investment from a Malaysian company backed by the country’s former premier Mahathir bin Mohamad, but not to begin full production. Its development was suspended on 16 March 2017 with the defection of Evektor's Malaysian investor.
The EV-55 is of conventional high-wing utility design with a T-tail. The prototype aircraft is powered by Pratt & Whitney PT6A-21 turboprop engines (535 shaft horsepower), driving four-blade propellers. The wing is mounted atop a nearly-square fuselage, which has five windows per side. The trailing-link tricycle landing gear retracts into the nose section or pods on the lower fuselage. Expected maximum cruise speed is 220 knots (407 km/h).
With nine passengers, range is 800nm (1,480km), it can take-off in 410m and land in 520m and with more speed, range and short take-off and landing capability, it can replace ageing piston-twins like the Cessna 421 and Britten-Norman Islander, or the smaller Cessna Caravan single turboprop when the payload-range of a larger turboprop such as the L-410 or Viking Twin Otter is not neeeded. The less expensive, unpressurised EV-55 won't compete with the Pilatus PC-12 or Beechcraft King Air. 
The 5.02m x 1.61m cabin standard layout is five and four seats with a cargo compartment separated by a semi bulkhead and a L-410 sized double door at the rear. It is equipped with a full glass cockpit, Czech firm Avia makes the four-blade propellers and Aero Vodochody the landing gear.
