Evektor EV-55 Outback is a twin-engine turboprop aircraft that was designed and is built in the Czech Republic by Evektor-Aerotechnik. The prototype first flew on 24 June 2011.[2][3]
Development
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.[3] It was estimated at $2.1 to $2.2 million in 2012.[4] The first production-conforming aircraft flew from Kunovice in April 2016.[5]
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.[1] Its development was suspended on 16 March 2017 with the defection of Evektor's Malaysian investor.[6]
Design
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).[5]
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 needed. The less expensive, unpressurised EV-55 won't compete with the Pilatus PC-12 or Beechcraft King Air. [1]
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.[1]
